All Compounds

BPC-157

Healing Peptide
Research Only

The gut-healing, tendon-repairing peptide that started the biohacking revolution.

evidence

Rapamycin

Longevity
Prescription

The only drug proven to extend lifespan in every organism tested. The longevity community's most controversial darling.

Nootropic Peptide
Research Only

Russia's prescription nootropic. Developed for stroke recovery, adopted by biohackers for focus and memory.

evidence

AOD-9604

Weight Loss
Research Only

The fat-burning fragment of growth hormone. Without the growth hormone side effects.

evidence

CJC-1295

Growth Hormone
Research Only

The long-acting growth hormone releaser that keeps your GH elevated for days, not minutes.

evidence

Ipamorelin

Growth Hormone
Research Only

The gentlest growth hormone peptide. Strong GH release without the hunger or cortisol spike.

evidence

PT-141

Sexual Health
Prescription

The only peptide that works on sexual desire itself — not just the plumbing, but the wanting.

evidence

Dihexa

Nootropic
Research Only

Ten million times more potent than BDNF at forming new synapses. The most powerful nootropic ever discovered — on paper.

evidence

Selank

Anxiolytic Peptide
Research Only

Russia's answer to anxiety. A peptide that calms without sedating, sharpens without stimulating.

evidence

Epitalon

Longevity
Research Only

The telomerase-activating peptide from Russia. Potentially the most direct anti-aging compound we have.

evidence

DSIP

Sleep
Research Only

The sleep peptide your brain makes naturally. Restores deep sleep architecture without next-day grogginess.

evidence

Cerebrolysin

Neuroprotective
Prescription

A cocktail of brain-derived peptides used clinically across 50+ countries. The West mostly ignores it. That might be a mistake.

evidence

LL-37

Antimicrobial
Research Only

Your immune system's first-line antimicrobial weapon. Now available as a standalone peptide.

evidence

Melanotan II

Cosmetic Peptide
Cosmetic

The tanning injection that also boosts libido and suppresses appetite. Popular, effective, and controversial.

evidence

NMN

Longevity
Legal Supplement

The NAD+ precursor that David Sinclair made famous. Direct fuel for your cellular repair machinery.

evidence

Resveratrol

Longevity
Legal Supplement

The red wine molecule that kicked off the sirtuin revolution. The science has matured — and it is more nuanced than headlines suggest.

evidence

Berberine

Metabolic
Legal Supplement

Nature's metformin. The plant compound that rivals prescription drugs for blood sugar control.

evidence

Quercetin

Senolytic
Legal Supplement

The flavonoid that helps clear zombie cells. Cheap, widely available, and backed by real senolytic science.

evidence

Fisetin

Senolytic
Legal Supplement

The most potent natural senolytic identified so far. Clears zombie cells more effectively than quercetin alone.

evidence

Spermidine

Longevity
Legal Supplement

The autophagy trigger hiding in aged cheese and wheat germ. One of the strongest dietary longevity signals we know of.

evidence

Methylene Blue

Mitochondrial
Prescription

A 150-year-old dye that doubles as a mitochondrial enhancer and neuroprotectant. Yes, it turns things blue.

evidence

Urolithin A

Mitochondrial
Legal Supplement

The gut metabolite that recycles damaged mitochondria. Your body might make it — or it might not.

evidence

Apigenin

Sleep & Longevity
Legal Supplement

The chamomile compound that promotes deep sleep, fights cancer, and boosts NAD+ levels. A quiet overachiever.

evidence

Pregnenolone

Neurosteroid
Legal Supplement

The mother of all steroid hormones. Your body makes every other hormone from this one precursor.

evidence

Oxytocin

Social Peptide
Prescription

The bonding molecule your brain already makes — now biohackers are using it to hack social anxiety and trust.

evidence

KPV

Anti-Inflammatory Peptide
Research Only

A tiny three-amino-acid fragment of alpha-MSH that packs serious anti-inflammatory punch — especially for the gut.

evidence

VIP (Vasoactive Intestinal Peptide)

Gut-Brain Peptide
Prescription

A 28-amino-acid peptide that bridges gut and brain function — used for CIRS, mould illness, and neuroinflammation.

evidence

MOTS-c

Mitochondrial Peptide
Research Only

A mitochondrial-derived exercise mimetic that activates AMPK and improves metabolic health — even without exercise.

evidence

Humanin

Neuroprotective Peptide
Research Only

A mitochondrial-derived peptide that protects neurons from death — potentially relevant for Alzheimer's and ageing.

evidence

Tissue Repair Peptide
Research Only

The copper-free form of GHK-Cu — a tissue remodelling peptide that resets gene expression toward a younger pattern.

evidence

Epithalon (Injectable)

Longevity Peptide
Research Only

The telomerase-activating tetrapeptide from Russian longevity research — now in injectable form for maximum bioavailability.

evidence
