This is a reference list of the peptides people search for by name, grouped by family. Each entry tells you what that peptide has been studied for, how strong the evidence is, how it is delivered, and whether it is a consumer supplement or a research-use-only compound. Nothing here is held back for the download, and the whole list is also a free PDF you can take without giving an email address.

Most peptide lists online sort by goal, which is useful when you already know what you want. This one sorts by name and class, because most people land here after reading a peptide name somewhere and wanting to know what it is.

How to Read This List

Every row carries five pieces of information, and the two that matter most are the evidence tier and the status. Those two columns are what separate a peptide with human trial data you can act on from one that has only been run in a dish.

Here is what each column means.

Column	What it tells you
Peptide	The name it is usually sold and searched under, plus common aliases
Class or family	The structural or functional group it belongs to
Studied for	The research area, not a promised outcome
Evidence	How strong the published human, animal or lab data is
Route	Oral, injectable, topical or intranasal
Status	Whether it is a consumer supplement, a research compound or a prescription drug

The evidence tiers work like this.

Tier	What it means
Human trials	Randomized controlled trials in people
Human, limited	Small, open label, single center, or from one research group
Animal	Rodent or other animal models only
Cell and lab	Cell culture, cell-free systems or computational modeling

And the status labels work like this.

Status	What it means
Consumer capsule	Sold by BioLongevity Supplements as an oral supplement for daily use
Research use only	Sold by the sister brand BioLongevity Labs for laboratory research, never for personal use
Prescription drug	An approved medicine that a clinician has to prescribe
Research compound	Studied in laboratories and not sold by either BioLongevity brand

One route note before the tables. A peptide’s chain length largely decides whether it survives a trip through the stomach, which is why some of these work in a capsule and most do not. Our guide to whether peptides can be taken orally explains where the size threshold sits.

If you want the goal-first version of this material instead, with the operating knowledge on forms, labels and storage, that lives in the peptide cheat sheet. This page is the index. That one is the guide.

Tissue Repair, Skin and Recovery Peptides

This family is the one most people meet first, because it contains the peptides that show up in recovery and skincare conversations. They are grouped together because they all act on tissue remodeling rather than a hormone axis.

Peptide	Also known as	Class or family	Studied for	Evidence	Route	Status
BPC-157	Body Protection Compound 157	15 amino acid gastric pentadecapeptide	Tendon, gut and soft tissue repair; vascular effects	Animal	Oral, injectable, topical	Consumer capsule (oral), research use only (injectable)
TB-500	Thymosin beta-4 fragment	43 residue synthetic thymosin beta-4	Actin regulation, cell migration, wound models	Animal	Injectable	Research use only
GHK-Cu	Copper tripeptide-1, Gly-His-Lys-Cu	Copper-binding tripeptide	Collagen and elastin synthesis, skin remodeling, hair follicle size	Human, limited	Topical, oral, injectable	Consumer capsule (oral), research use only (injectable)
ARA-290	Cibinetide	11 amino acid erythropoietin-derived peptide	Small nerve fiber abundance, neuropathic pain	Human trials	Injectable	Research use only
Elamipretide	SS-31, BioAmplify	Mitochondria-targeting tetrapeptide	Cardiolipin binding and mitochondrial function	Human trials	Injectable	Research use only
AK peptide complexes	AK-1, AK-3, AK-7, AK-8, AK-9, AK-12	Tissue-specific topical peptide complexes	Skin barrier and topical recovery formulas	Cell and lab	Topical	Consumer topical

BPC-157 is the most searched name on this page and the one most often described loosely. A 2026 review in Pharmaceutics is blunt about where it stands: three decades of preclinical work, activity by oral, injected and topical routes, and no completed phase 2 clinical trial. That is a deep and consistent animal evidence base, which is exactly what the tier label says.

GHK-Cu sits a tier higher. A review of the copper tripeptide describes controlled work in aged skin reporting better firmness and elasticity and fewer fine lines. It also lists effects on collagen, elastin and growth factor expression.

ARA-290 is the surprise in this group. In a phase 2b randomized trial in people with sarcoidosis-associated small fiber loss, cibinetide increased corneal nerve fiber area and regenerating intraepidermal fibers compared with placebo. It is still a research compound, but the human data behind it is real.

Gut, Barrier and Immune Peptides

These peptides act on the intestinal lining or on immune signaling, and this is the family with the strongest oral track record. Short chains and dedicated transport routes are the reason.

Peptide	Also known as	Class or family	Studied for	Evidence	Route	Status
KPV	Lys-Pro-Val, alpha-MSH C-terminal fragment	Tripeptide	Intestinal inflammation, NF-kB signaling	Animal	Oral, injectable	Consumer capsule (oral), research use only (injectable)
N-acetyl larazotide	Larazotide acetate, AT-1001	8 amino acid tight junction regulator	Intestinal permeability, gluten-related symptoms	Human trials	Oral	Consumer capsule
LL-37	CAP-18, cathelicidin fragment	37 amino acid antimicrobial peptide	Antimicrobial activity, innate immune signaling	Cell and lab	Injectable	Research use only
Thymosin alpha-1	Thymalfasin, Ta1	28 amino acid thymic peptide	Immune modulation, T-cell function	Human trials	Injectable	Research use only
Thymulin	Zinc-dependent thymic nonapeptide	Thymic peptide	T-cell differentiation	Cell and lab	Injectable	Research use only
VIP	Vasoactive intestinal peptide	28 amino acid neuropeptide	Vasodilation, gut and immune signaling	Cell and lab	Injectable, intranasal	Research use only

KPV is three amino acids long, which means the gut has a transporter built for it. Research published in Gastroenterology showed KPV is taken into intestinal epithelial and immune cells through PepT1 and reduced inflammation markers in two mouse colitis models.

Larazotide acetate has the strongest human evidence of anything in this section. In a randomized, double-blind, placebo-controlled trial in 342 adults, the lowest dose arm reduced symptoms compared with placebo, with safety comparable to placebo.

Thymosin alpha-1 is a good example of why the evidence column matters. It has genuine phase 3 human data, and that data is mixed. A 2025 multicenter trial in 1,106 adults with sepsis found no reduction in 28 day mortality compared with placebo. Human trial data is the strongest tier available, and it does not always come back positive.

BioGutPro carries four entries from this page in one capsule: BPC-157, KPV, GHK-Cu and N-acetyl larazotide. Tributyrin and zinc L-carnosine round out the formula, and every amount is printed on the label.

Metabolic and Body Composition Peptides

These are the peptides tied to appetite, fat distribution and energy metabolism, and this family has moved fastest in the last five years. Several are approved drugs rather than supplements.

Peptide	Also known as	Class or family	Studied for	Evidence	Route	Status
Cagrilintide	AM833	Long-acting acylated amylin analog	Appetite regulation, body weight	Human trials	Injectable	Research use only
Tesamorelin	Egrifta	GHRH analog	Visceral adipose tissue, muscle density	Human trials	Injectable	Prescription drug, research use only as a lab compound
MOTS-c	Mitochondrial ORF of the 12S rRNA type-c	16 amino acid mitochondrial-derived peptide	Metabolic regulation, AMPK signaling, exercise biology	Animal	Injectable	Research use only
Semaglutide	Ozempic, Wegovy	GLP-1 receptor agonist	Glycemic control, body weight	Human trials	Injectable, oral	Prescription drug
Tirzepatide	Mounjaro, Zepbound	Dual GIP and GLP-1 agonist	Glycemic control, body weight	Human trials	Injectable	Prescription drug
AOD-9604	hGH fragment 176-191	Growth hormone C-terminal fragment	Lipolysis in animal models	Animal	Injectable, oral	Research compound

Cagrilintide is the newest name most people are looking up. In a phase 2 dose-finding trial across ten countries, once-weekly cagrilintide produced dose-dependent weight reduction compared with placebo in adults with overweight and obesity.

Tesamorelin is the clearest case of a peptide that graduated. It is an approved medicine, and in a secondary analysis of two randomized trials in adults living with HIV, it increased truncal muscle density and area against placebo.

Growth Hormone and Muscle Signaling Peptides

These peptides act on the growth hormone axis or on muscle-specific signaling, and almost all of them are injectable research compounds rather than supplements. None of them are oral.

Peptide	Also known as	Class or family	Studied for	Evidence	Route	Status
Ipamorelin		Pentapeptide growth hormone secretagogue	Selective growth hormone release	Animal	Injectable	Research use only
CJC-1295 (no DAC)	Modified GRF 1-29	GHRH analog	Growth hormone pulse amplitude	Animal	Injectable	Research use only
PEG-MGF	PEGylated mechano growth factor	24 residue IGF-1Ec E-domain fragment	Muscle repair signaling after mechanical load	Cell and lab	Injectable	Research use only
IGF-1 LR3 analogs	BioIGF-LR	Long-acting IGF-1 analog	IGF-1 axis research	Cell and lab	Injectable	Research use only
FLGR242		Selective myostatin pathway inhibitor	Myostatin signaling in muscle models	Cell and lab	Injectable	Research use only

Ipamorelin and CJC-1295 are almost always searched together because they are sold as a combined vial. They work on two different receptors, which is the reason they get paired: one is a ghrelin receptor agonist and the other mimics growth hormone-releasing hormone.

Brain, Mood and Sleep Peptides

This family covers the neuropeptides studied for cognition, anxiety and sleep architecture. Several have decades of clinical use in Russia and very little Western trial data, which is why most sit in the limited human tier.

Peptide	Also known as	Class or family	Studied for	Evidence	Route	Status
Semax	N-acetyl semax amidate, ACTH(4-10) analog	Melanocortin-derived neuropeptide	Cognition, neuroprotection, stroke recovery models	Human, limited	Intranasal, injectable	Research use only
Selank	Tuftsin analog	Heptapeptide	Anxiety and stress response models	Human, limited	Intranasal	Research compound
DSIP	Delta sleep-inducing peptide	9 amino acid neuropeptide	Sleep architecture, stress response	Cell and lab	Injectable	Research use only
Noopept	N-phenylacetyl-L-prolylglycine ethyl ester	Dipeptide-derived nootropic	Memory and cognitive endpoints	Human, limited	Oral	Research compound
Oxytocin		9 amino acid neurohypophysial hormone	Social behavior, uterine contraction	Human trials	Injectable, intranasal	Prescription drug, research use only as a lab compound

If Noopept is the name that brought you here, we have a longer piece on what the noopept research covers.

Sexual Health and Hormone Signaling Peptides

These peptides act on melanocortin receptors or the reproductive hormone axis. Two of them are approved drugs, which makes this family unusual on a peptide list.

Peptide	Also known as	Class or family	Studied for	Evidence	Route	Status
PT-141	Bremelanotide, Vyleesi	7 amino acid melanocortin receptor agonist	Sexual desire and related distress	Human trials	Injectable, intranasal	Prescription drug, research use only as a lab compound
Melanotan-1	Afamelanotide, Scenesse	Alpha-MSH analog	Photoprotection, melanin density	Human trials	Injectable implant	Prescription drug, research use only as a lab compound
Melanotan-2	MT-2	Alpha-MSH analog	Pigmentation and melanocortin signaling	Cell and lab	Injectable	Research compound
Kisspeptin-10	KP-10	Decapeptide	GnRH release and the reproductive axis	Human, limited	Injectable	Research use only

PT-141 has two identical phase 3 trials behind it. Across 1,267 randomized premenopausal women, bremelanotide improved sexual desire scores and reduced related distress compared with placebo, and both trials met their primary endpoints.

Melanotan-1 is the same molecule as afamelanotide, which was tested in two randomized placebo-controlled trials in patients with erythropoietic protoporphyria and increased pain-free sun exposure time. The approved implant and the research vial are chemically the same peptide sold under completely different rules.

Cellular Aging and Longevity Peptides

This family is studied for senescence, telomere biology and the pathways associated with biological aging. The evidence here is the earliest on the page, and the honest labels reflect that.

Peptide	Also known as	Class or family	Studied for	Evidence	Route	Status
Epithalon	Epitalon, AEDG	Khavinson tetrapeptide	Telomerase activity in cell models, melatonin rhythm	Human, limited	Injectable, oral	Research use only
FOXO4-DRI	Proxofim	D-retro-inverso peptide	Senescent cell clearance	Animal	Injectable	Research use only
Klotho	AlphaKlotho-LR	Recombinant protein with albumin-binding peptide	Aging biology and kidney signaling	Animal	Injectable	Research use only
PNC-27		32 residue p53 HDM-2 chimeric peptide	Tumor cell membrane models	Cell and lab	Injectable	Research use only

Epithalon is the most searched longevity peptide, and its best human result is a modest one. A study of the pineal peptide preparation in older adults found it shifted nighttime melatonin toward a younger pattern, raising it in people whose pineal activity had declined. That is a real physiological change in people. It is not a lifespan outcome, and nobody should present it as one.

The 21 Khavinson Bioregulators, A-1 Through A-21

These are the oral peptide bioregulators, and they are the only family on this page sold as everyday capsules across the whole range. Each is named for the tissue it was developed around, and each carries two names: a Khavinson name from the original Russian research and a BioLongevity product name.

A systematic review of peptide regulation of gene expression reports that short peptides of two to seven residues can enter cell nuclei and bind histone proteins and DNA. That is the proposed mechanism behind the whole class. The background on how that works is in our explainer on what peptide bioregulators are.

All 23 entries below are oral capsules with consumer supplement status.

Complex	Khavinson name	BioLongevity name	Tissue focus
A-1	Suprefort	BioPancreas	Pancreas
A-2	Thyreogen	BioThyroid	Thyroid
A-3	Ventfort	BioBloodVessels	Blood vessels
A-4	Sigumir	BioCartilage	Cartilage
A-5	Cerluten	BioNervousSystem	Nervous system
A-6	Vladonix	BioThymus	Thymus
A-7	Svetinorm	BioLiver	Liver
A-8	Endoluten	BioPineal	Pineal gland
A-9	Pielotax	BioKidney	Kidney
A-10	Stamakort	BioStomach	Stomach
A-11	Visoluten	BioRetina	Retina
A-12	Chitomur	BioBladder	Bladder
A-13	Testoluten	BioTestes	Testes
A-14	Chelohart	BioHeart	Heart
A-15	Zhenoluten	BioOvary	Ovary
A-16	Libidon	BioProstate	Prostate
A-17	Glandokort	BioAdrenal	Adrenal glands
A-18	Gotratix	BioMuscle	Skeletal muscle
A-19	Taxorest	BioLung	Lungs
A-20	Bonomarlot	BioBoneMarrow	Bone marrow
A-21	Bonothyrk	BioParathyroid	Parathyroid
Geroprotector	GPL Man	BioMale	Multi-system complex for men
Geroprotector	GPL Femme	BioFemale	Multi-system complex for women

Evidence for this family sits in the human, limited tier. The published human work comes overwhelmingly from one research program in St Petersburg and has not been independently replicated by Western trials.

The Khavinson Injectable Short Peptides

These are the synthetic short peptides from the same research lineage, sold as lyophilized powder for laboratory research rather than as capsules. They are often called cytogens, and the sequences are two to four amino acids long.

Every entry here is research use only and is not for personal use.

Peptide	Sequence	Tissue focus in the research
Bronchogen	Ala-Glu-Asp-Leu (AEDL)	Bronchial and lung tissue
Cardiogen	Ala-Glu-Asp-Arg (AEDR)	Cardiac fibroblasts and cardiomyocytes
Cartalax	Ala-Glu-Asp (AED)	Cartilage and bone metabolism
Chonluten	Tripeptide, also labelled T-34	Bronchial mucosa
Cortagen	Ala-Glu-Asp-Pro (AEDP)	Brain cortex and nervous system
Livagen	Lys-Glu-Asp-Ala (KEDA)	Liver tissue models
Ovagen	Glu-Asp-Leu (EDL)	Kidney tissue models
Pancragen	Lys-Glu-Asp-Trp (KEDW)	Pancreatic tissue
Pinealon	Short peptide cytogen	Neuronal cell models
Prostamax	Tetrapeptide	Prostate tissue
Testagen	Lys-Glu-Asp-Gly (KEDG)	Pituitary and thyroid signaling
Thymagen	Glu-Trp (Thymogen)	Thymus and immune signaling
Vesilute	Glu-Asp	Urinary tract tissue
Vesugen	Lys-Glu-Asp (KED)	Vascular endothelium
Vilon	Khavinson short peptide	Immune cell signaling and gene expression

The history behind this whole series, and the researcher it is named for, is covered in our piece on Khavinson peptides.

Peptide Blends Sold Under a Single Name

Two blend names come up constantly in peptide searches, and both are single research vials containing several peptides from the tables above. Neither is a consumer supplement.

Blend	Composition	Total per vial	Route	Status
GLOW	GHK-Cu 50 mg, BPC-157 10 mg, TB-500 10 mg	70 mg	Injectable	Research use only
KLOW	GHK-Cu 50 mg, BPC-157 10 mg, TB-500 10 mg, KPV 10 mg	80 mg	Injectable	Research use only

KPV is the only difference between them. Our breakdown of what the GLOW blend contains walks through each component. KLOW vs GLOW covers what that fourth peptide changes.

Compounds Filed Under Peptides That Are Not Peptides

Several compounds get grouped with peptides in supplement listings and search results without being peptides at all. They are small molecules, coenzymes or amino acid derivatives, and knowing the difference tells you a lot about how each one behaves.

Compound	What it actually is	Studied for	Evidence	Route	Where you will find it
SLU-PP-332	Synthetic ERR nuclear receptor agonist	Energy expenditure and fatty acid oxidation	Animal	Oral, injectable	ShredMAX
5-Amino-1MQ	Small-molecule NNMT inhibitor	NAD salvage pathway, muscle stem cell activity	Animal	Oral, injectable	Research use only as a standalone
BAM15	Mitochondrial protonophore and uncoupler	Energy expenditure, glycemic control	Animal	Oral	BioBam-15
ATX-304	Direct AMPK activator	AMPK pathway activation	Early stage	Oral	BioAmp
Tesofensine	Triple monoamine reuptake inhibitor	Appetite and body weight	Human trials	Oral	BioFlow
NAD+	Coenzyme, not a peptide	Cellular energy and sirtuin activity	Human, limited	Oral, injectable	Research use only as an injectable
Collagen peptides	Hydrolyzed protein fragments	Skin and joint endpoints	Human trials	Oral	Widely sold as a food supplement
L-carnitine	Quaternary ammonium compound	Fatty acid transport	Human trials	Oral, injectable	Research use only as an injectable

The evidence spread across this group is wide. SLU-PP-332 increased energy expenditure and fatty acid oxidation and reduced fat mass in diet-induced obese mice, which is promising animal work. NNMT inhibition improved muscle stem cell activity and regeneration in 24 month old mice, with roughly 70% greater peak torque in treated animals. BAM15 protected against diet-induced obesity and improved glycemic control in mice.

Tesofensine is the outlier: it has phase 2 human data. In a randomized, double-blind, placebo-controlled trial in 203 adults, the middle dose arm produced 9.2% mean weight loss over 24 weeks against 2.0% on diet and placebo. Heart rate rose in that group, which is a real consideration for anyone taking cardiovascular or stimulant medication.

Collagen peptides deserve one clarifying line, because they are the most common source of confusion on this whole page. They are a nutrient your body digests into amino acids and reuses. Every other peptide on this list is studied as a signal.

Frequently Asked Questions

A few questions come up almost every time someone works through a list like this one.

What is the difference between a peptide and a protein?

Length. Peptides are short chains of amino acids, generally under about 50 residues, while proteins are longer and fold into complex three-dimensional shapes. Most of the peptides on this page are under 40 amino acids, and the bioregulators are two to four.

Which peptides on this list can be taken orally?

The short ones, mostly. Peptides two to three amino acids long have a dedicated intestinal transporter. The Khavinson bioregulators sit in the size range studied for oral use, and BPC-157 is unusually stable in gastric conditions. Anything over about 30 amino acids needs injection or a delivery system.

What does research use only actually mean?

It means the compound is sold to laboratories for in vitro and preclinical work and is not approved or intended for human use. It is a legal and regulatory status, not a quality grade. A research use only compound can be 99% pure and still not be something a person should take.

Are any of these peptides FDA approved?

A few. Tesamorelin, bremelanotide, afamelanotide, semaglutide, tirzepatide and oxytocin are approved medicines with prescription status. Everything else on this page is either a dietary supplement ingredient or a research compound.

Why do some peptides have two or three different names?

Because most of them were named once in the research literature, again by a manufacturer, and again by a brand. Epithalon and Epitalon are the same compound, PT-141 and bremelanotide are the same compound, and every Khavinson bioregulator carries both a Russian research name and a product name.

Where can I download this list as a PDF?

The complete chart is available as a free PDF download with no email required. It is formatted for printing and covers every table on this page.
