Semaglutide
Ozempic · Wegovy · Rybelsus
The GLP-1 receptor agonist that turned obesity pharmacology into a mainstream conversation. Once-weekly injection, ~7-day half-life, and the largest randomised dataset of anything in this catalogue.
Tirzepatide
Mounjaro · Zepbound
Dual GIP and GLP-1 agonist. Beats Semaglutide head-to-head on weight loss and glycaemic control, and is becoming the default first-line choice when both are available.
BPC-157
Body Protection Compound · Pentadecapeptide BPC-157
A 15-amino-acid stretch lifted from a protein in human gastric juice. Best-known use is soft-tissue repair, with a quieter second life as a gut-healing protocol.
Retatrutide
LY3437943
Triple agonist hitting GIP, GLP-1, and glucagon receptors at once. Phase 2 data shows the largest weight-loss numbers ever reported for a drug in trials — ~24% at 48 weeks.
TB-500
Thymosin Beta-4 · TB-4
A synthetic fragment of Thymosin Beta-4 used for systemic tissue repair. Sister peptide to BPC-157, but where BPC works locally, TB-500 spreads.
HGH (Somatropin)
Somatropin · Human Growth Hormone · GH
Recombinant human growth hormone — the actual hormone itself, not a secretagogue. Powerful for body recomposition, with side effects that scale unmistakably with dose.
CJC-1295 / Ipamorelin
CJC + Ipa · Mod-GRF + Ipamorelin · GHRH+GHRP stack
The workhorse GH-secretagogue stack: a GHRH analogue paired with a selective ghrelin agonist. GHRH plus GHRP produces more GH per pulse than either alone, with a side-effect profile most people find tolerable for indefinite use.
GHK-Cu
Copper Peptide · Glycyl-L-Histidyl-L-Lysine Copper
The copper-binding tripeptide your skin loses with age. Strongest evidence is topical for skin and wound healing; injectable use is mostly anecdotal.
Epithalon
Epitalon · Epithalamin
A Khavinson-school tetrapeptide (Ala-Glu-Asp-Gly) marketed for telomere lengthening and pineal regulation. The telomere claim rests on small Russian studies; the sleep effect is the more honest reason people use it.
Ipamorelin
Ipam
A selective ghrelin-receptor agonist that triggers a GH pulse without raising cortisol or prolactin — the property that made it the default GHRP and pushed the older, dirtier GHRPs to the margins.
CJC-1295 (no DAC)
Mod-GRF(1-29) · CJC-1295 without DAC
A short-acting GHRH analogue — the GH pulse it produces is sharp, brief, and very close to what the pituitary does on its own. Stabilised against rapid breakdown, but without the albumin-binding modification that turns it into the long-acting DAC version.
Melatonin
N-acetyl-5-methoxytryptamine
The body's own sleep-onset hormone, sold as an over-the-counter supplement in most jurisdictions. Effective and cheap when used correctly — and chronically overdosed by almost everyone who uses it.
PT-141
Bremelanotide · Vyleesi
Melanocortin-receptor agonist that works on desire in the brain, not blood flow in the pelvis. FDA-approved as Vyleesi for premenopausal HSDD.
IGF-1 LR3
IGF-1 LR3 · Long R3 IGF-1
The growth signal one step downstream of GH, with an extended half-life and a real hypoglycaemia risk. The most directly anabolic peptide a non-medical user can buy, and the one with the most teeth.
Semax
ACTH(4-7) analogue
A Russian-developed heptapeptide based on a fragment of ACTH(4-10). Used intranasally as a focus and neuroprotection tool — registered in Russia, almost unknown in Western clinical practice.
CJC-1295 with DAC
CJC-1295 with DAC · Drug Affinity Complex CJC-1295
The long-acting version: the same GHRH analogue plus a Drug Affinity Complex that lets it bind albumin reversibly, stretching the half-life from minutes to days. Convenience peptide — one shot a week — at the cost of the pulsatile pattern.
NAD+
NAD+ · Nicotinamide Adenine Dinucleotide
Technically a coenzyme rather than a peptide — central to energy metabolism, DNA repair, and sirtuin activity. Levels fall with age; injectable and IV protocols try to restore them.
Selank
TP-21
A Russian tuftsin-derived heptapeptide used intranasally for anxiety without sedation. Approved domestically as an anxiolytic; the Western evidence base is thin but the user reports are consistent.
Sermorelin
Sermorelin Acetate · GRF 1-29
The oldest GHRH analogue still in widespread use — the first 29 amino acids of natural GHRH, unmodified. Pulses the pituitary in line with the body's natural sleep-onset GH window.
Tesamorelin
Egrifta
A stabilised GHRH analogue with an FDA approval for HIV-associated lipodystrophy — the only growth-hormone-axis secretagogue with a genuine regulatory signal. Famous for selectively shrinking visceral fat.
Mazdutide
IBI362 · LY3305677
Chinese-developed GLP-1 / glucagon co-agonist (IBI362, licensed from Eli Lilly's LY3305677). Solid Phase 2 data, approved in China for diabetes in 2024, investigational elsewhere.
Thymosin Alpha-1
Tα1 · Zadaxin
A 28-amino-acid thymic peptide marketed as Zadaxin. Approved in over 30 countries for hepatitis B and C; used off-label for chronic infection and immune resilience.
CagriSema
CagriSema · Cagrilintide + Semaglutide
Once-weekly fixed-dose combination of Cagrilintide and Semaglutide. The leading 'next-generation' obesity treatment in Phase 3, delivering roughly 20% weight loss in late trials.
HCG
Human Chorionic Gonadotropin
Human chorionic gonadotropin — a placental hormone that mimics LH and tells the testes to keep making testosterone and sperm. The most clinically established HPG-axis tool in this catalogue.
DSIP
Delta Sleep-Inducing Peptide
A 9-amino-acid peptide originally isolated from rabbit brain on the hypothesis that it triggers delta-wave sleep. The real-world signal in humans is mixed and the trial base is small and old.
KPV
Lysine-Proline-Valine
The three-amino-acid tail of α-MSH. Anti-inflammatory in test tubes and animals; some small IBD signal in humans.
MOTS-c
Mitochondrial Open Reading Frame
A 16-amino-acid peptide encoded inside the mitochondrial genome — the cell's own metabolic stress signal. Animal data on insulin sensitivity is good; human data is small but growing.
Cagrilintide
AM833
Long-acting amylin analogue for once-weekly dosing. Useful on its own; dramatically more useful paired with Semaglutide as the CagriSema combination.
GHRP-2
GHRP-2 Acetate · Pralmorelin
A ghrelin-mimetic hexapeptide that produces a sharp GH pulse with only modest appetite stimulation. The balanced middle child of the GHRP family.
Melanotan-2
MT-2
The unregulated tanning peptide. Cheaper and more effective on libido than MT-1, but the side effect profile and mole-change risk make this the riskier of the two.
AOD9604
Anti-Obesity Drug 9604
A short fragment of human growth hormone (residues 177-191) that was sold the lipolytic tail of HGH without the growth signal. The marketing outpaced the trial data by a wide margin.
GHRP-6
GHRP-6 Acetate
The hungry one. A ghrelin-mimetic that delivers a real GH pulse but is far better known for the appetite avalanche that arrives twenty minutes after the injection.
Hexarelin
Hexarelin Acetate
The most potent GHRP per microgram — and the one that desensitises fastest. A short-cycle tool, not a long-term protocol, with a cortisol lift that Ipamorelin avoids.
Gonadorelin
Gonadorelin Acetate · GnRH
Synthetic GnRH — the pulsatile signal from the hypothalamus that tells the pituitary to release LH and FSH. The upstream lever in the HPG axis.
5-Amino-1MQ
5-amino-1-methylquinolinium · NNMT inhibitor
An orally bioavailable small-molecule inhibitor of NNMT (nicotinamide N-methyltransferase). Plenty of compelling rodent data, almost no human data, and a forum community that has gotten ahead of the science.
Oxytocin
Oxytocin Acetate
The body's bonding hormone, repurposed as intranasal spray for social and intimacy effects. The hype outpaces the trial data.
Melanotan-1
MT-1 · Afamelanotide
An α-MSH analogue approved in the EU and US as Scenesse (afamelanotide) for erythropoietic protoporphyria. The off-label tanning use is what most people actually want it for.
GLOW Stack
GLOW · TB + BPC + GHK-Cu
A pre-blended convenience vial containing TB-500, BPC-157 and GHK-Cu in one daily injection. Marketed as a recovery-plus-skin protocol.
Lipo-C (MIC)
Lipo-C · MIC blend · Lipotropic Injection
A vitamin-and-amino-acid injection blend - methionine, inositol, choline, B12, sometimes more. It is not a peptide and it is not a fat-burner. It is an old-school clinic adjunct with decades of use and almost no RCT support.
Thymalin
Thymalin
A thymic peptide preparation developed in the Soviet bioregulator program. Used in Russia for decades as an immune support adjunct; Western trial data is sparse.
Survodutide
Survodutide
Boehringer Ingelheim's investigational GLP-1 / glucagon dual agonist. Phase 2 weight loss in the 15–19% range, with a notable side-effect on liver fibrosis in NASH patients.
SS-31 (Elamipretide)
Elamipretide · MTP-131 · Bendavia
A four-amino-acid peptide that homes to the inner mitochondrial membrane and stabilises cardiolipin. Currently the most clinically advanced mitochondrial peptide in trials.
Kisspeptin-10
Kp-10 · Metastin
The upstream trigger of the entire reproductive axis. Early human trials hint at uses for HSDD and hypothalamic amenorrhea; nothing is approved.
MGF (Mechano Growth Factor)
Mechano Growth Factor · IGF-1Ec
A splice variant of IGF-1 that the body produces locally inside exercising muscle. Used as a post-workout intramuscular shot to amplify the local growth signal in trained tissue only.
KLOW Stack
KLOW · TB + BPC + GHK + KPV
GLOW plus KPV — the same TB-500 + BPC-157 + GHK-Cu blend with an added anti-inflammatory tripeptide. Marketed at users with gut or chronic-inflammation overlap.
FOXO4-DRI
FOXO4 · FOXO4-DRI
The headline senolytic peptide — it disrupts the FOXO4–p53 interaction inside senescent cells, pushing them into apoptosis while sparing healthy cells. Striking in mice, untested in humans.
PEG-MGF
PEG-MGF · PEGylated MGF
Pegylated MGF — the same satellite-cell-activating peptide as regular MGF, but with a polyethylene glycol chain that stretches the half-life from minutes to days. Trades the locality story for twice-weekly convenience.
Fat Blaster
L-Carnitine + B-vitamin blend
Lipo-C's training-focused cousin: the same B-vitamin core plus L-carnitine to support fatty-acid transport into mitochondria. Old-school clinic blend, not a peptide, and the trial data is thin.
SNAP-8
Acetyl Glutamyl Octapeptide-3
A topical octapeptide marketed as a 'Botox alternative'. The mechanism is real; the magnitude is nothing like an injection.
AICAR
5-Aminoimidazole-4-carboxamide ribonucleotide
An AMPK activator that turns on the molecular pathway exercise normally activates. Famous as the "exercise in a syringe" rodent paper and infamous as a WADA-banned substance.
LL-37
LL-37 · Cathelicidin
The body's main cathelicidin — a broad-spectrum antimicrobial peptide. Strong in vitro, useful in topical research, almost nothing settled about systemic use.
Lemon Bottle
Lipolytic Solution
A localised cosmetic fat-dissolving injectable - riboflavin, lecithin, bromelain - applied by aestheticians to small fat pockets like the submental area, jawline, or love handles. Contouring tool, not a weight-loss treatment.
Super Human Blend
Amino Acid Stack
A vendor-marketed multi-amino-acid injection - arginine, ornithine, citrulline, lysine, glutamine, proline, taurine, carnitine. Not a designed-by-trial protocol. A convenience preparation for users who want a single injection instead of a supplement shelf.
Pinealon
EDR tripeptide
A Khavinson-school tripeptide (Glu-Asp-Arg) for cognitive support in older adults. Used in short, intermittent courses; the published evidence is mostly from Russian gerontology research.
SLU-PP-332
SLU-PP-332
A small-molecule pan-agonist of estrogen-related receptors (ERR alpha/beta/gamma) developed academically. In mice, it produces exercise-like adaptations and meaningful fat loss. In humans, there is zero clinical data. Treat it as the experimental tool it actually is.
HMG
Human Menopausal Gonadotropin · Menotropin
Human menopausal gonadotropin — extracted from postmenopausal urine and containing both LH and FSH activity. The FSH supply that HCG can't provide.
VIP (Vasoactive Intestinal Peptide)
Vasoactive Intestinal Peptide
A 28-amino-acid neuropeptide repurposed intranasally for chronic inflammatory response syndrome under the Shoemaker protocol. The clinical evidence is largely from a single practitioner network.
Dermorphin
Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser-NH2
A heptapeptide from frog skin that is 30–40 times stronger than morphine at the mu-opioid receptor. Listed for completeness; the abuse risk is real.
