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.

Fat lossBeginner-friendly

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.

Muscle growthIntermediate

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.

Skin & hairBeginner-friendly

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.

Anti-agingIntermediate

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.

View details

Muscle growthBeginner-friendly

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.

View details

Muscle growthIntermediate

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.

View details

SleepBeginner-friendly

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.

Sexual healthIntermediate

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.

Muscle growthAdvanced

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.

View details

CognitiveBeginner-friendly

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.

View details

Muscle growthIntermediate

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.

Anti-agingBeginner-friendly

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.

View details

CognitiveBeginner-friendly

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.

Muscle growthBeginner-friendly

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.

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.

SleepBeginner-friendly

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.

Skin & hairIntermediate

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.

Muscle growthIntermediate

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.

Muscle growthIntermediate

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.

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.

Fat Blaster

L-Carnitine + B-vitamin blend
