All Compounds
BPC-157
Healing PeptideThe gut-healing, tendon-repairing peptide that started the biohacking revolution.
NAD+
LongevityThe cellular fuel that declines with age. Replenishing it might be the closest thing to an anti-aging supplement we have.
Semaglutide
Weight LossThe weight loss drug that changed everything. FDA-approved, clinically proven, and genuinely revolutionary.
MK-677
Growth HormoneThe oral growth hormone secretagogue. All the GH benefits without injections — in theory.
GHK-Cu
Anti-AgingThe skin regeneration peptide hiding in your own blood. Proven in topical form, fascinating when injected.
Thymosin Beta-4
Healing PeptideThe universal healing peptide. If BPC-157 is the gut specialist, TB-500 is the whole-body repair crew.
Tirzepatide
Weight LossSemaglutide's bigger, stronger cousin. Dual-action weight loss that's breaking clinical records.
Rapamycin
LongevityThe only drug proven to extend lifespan in every organism tested. The longevity community's most controversial darling.
Metformin
LongevityThe cheap diabetes drug that might slow aging. £2 per month and it's been around for 60 years.
Semax
Nootropic PeptideRussia's prescription nootropic. Developed for stroke recovery, adopted by biohackers for focus and memory.
AOD-9604
Weight LossThe fat-burning fragment of growth hormone. Without the growth hormone side effects.
CJC-1295
Growth HormoneThe long-acting growth hormone releaser that keeps your GH elevated for days, not minutes.
Ipamorelin
Growth HormoneThe gentlest growth hormone peptide. Strong GH release without the hunger or cortisol spike.
PT-141
Sexual HealthThe only peptide that works on sexual desire itself — not just the plumbing, but the wanting.
Dihexa
NootropicTen million times more potent than BDNF at forming new synapses. The most powerful nootropic ever discovered — on paper.
Selank
Anxiolytic PeptideRussia's answer to anxiety. A peptide that calms without sedating, sharpens without stimulating.
Epitalon
LongevityThe telomerase-activating peptide from Russia. Potentially the most direct anti-aging compound we have.
DSIP
SleepThe sleep peptide your brain makes naturally. Restores deep sleep architecture without next-day grogginess.
Cerebrolysin
NeuroprotectiveA cocktail of brain-derived peptides used clinically across 50+ countries. The West mostly ignores it. That might be a mistake.
LL-37
AntimicrobialYour immune system's first-line antimicrobial weapon. Now available as a standalone peptide.
Melanotan II
Cosmetic PeptideThe tanning injection that also boosts libido and suppresses appetite. Popular, effective, and controversial.
NMN
LongevityThe NAD+ precursor that David Sinclair made famous. Direct fuel for your cellular repair machinery.
Resveratrol
LongevityThe red wine molecule that kicked off the sirtuin revolution. The science has matured — and it is more nuanced than headlines suggest.
Berberine
MetabolicNature's metformin. The plant compound that rivals prescription drugs for blood sugar control.
Quercetin
SenolyticThe flavonoid that helps clear zombie cells. Cheap, widely available, and backed by real senolytic science.
Fisetin
SenolyticThe most potent natural senolytic identified so far. Clears zombie cells more effectively than quercetin alone.
Spermidine
LongevityThe autophagy trigger hiding in aged cheese and wheat germ. One of the strongest dietary longevity signals we know of.
Methylene Blue
MitochondrialA 150-year-old dye that doubles as a mitochondrial enhancer and neuroprotectant. Yes, it turns things blue.
Urolithin A
MitochondrialThe gut metabolite that recycles damaged mitochondria. Your body might make it — or it might not.
Apigenin
Sleep & LongevityThe chamomile compound that promotes deep sleep, fights cancer, and boosts NAD+ levels. A quiet overachiever.
Pregnenolone
NeurosteroidThe mother of all steroid hormones. Your body makes every other hormone from this one precursor.
Oxytocin
Social PeptideThe bonding molecule your brain already makes — now biohackers are using it to hack social anxiety and trust.
KPV
Anti-Inflammatory PeptideA tiny three-amino-acid fragment of alpha-MSH that packs serious anti-inflammatory punch — especially for the gut.
VIP (Vasoactive Intestinal Peptide)
Gut-Brain PeptideA 28-amino-acid peptide that bridges gut and brain function — used for CIRS, mould illness, and neuroinflammation.
MOTS-c
Mitochondrial PeptideA mitochondrial-derived exercise mimetic that activates AMPK and improves metabolic health — even without exercise.
Humanin
Neuroprotective PeptideA mitochondrial-derived peptide that protects neurons from death — potentially relevant for Alzheimer's and ageing.
GHK
Tissue Repair PeptideThe copper-free form of GHK-Cu — a tissue remodelling peptide that resets gene expression toward a younger pattern.
Epithalon (Injectable)
Longevity PeptideThe telomerase-activating tetrapeptide from Russian longevity research — now in injectable form for maximum bioavailability.
Thymalin
Immune PeptideA thymus-derived peptide that restores immune function in ageing — the other half of Khavinson's longevity protocol.
Pinealon
Sleep & Circadian PeptideA pineal gland tripeptide that normalises circadian rhythm and melatonin production — for when your sleep clock is broken.
Cortagen
Brain PeptideA cerebral cortex peptide bioregulator for cognitive recovery and brain ageing — Khavinson's nootropic peptide.
Retatrutide
Weight Loss PeptideThe next-gen triple agonist (GLP-1/GIP/Glucagon) that produced 24% weight loss in trials — making Semaglutide look modest.
Survodutide
Weight Loss PeptideBoehringer Ingelheim's dual GLP-1/Glucagon agonist — targeting both appetite and metabolic rate for obesity and liver disease.
Liraglutide
Weight Loss PeptideThe first GLP-1 weight loss injection (Saxenda) — now the 'tried and tested' option with years of real-world data behind it.
Tesamorelin
Growth Hormone PeptideThe only FDA-approved growth hormone releasing peptide — originally for HIV lipodystrophy, now used for body composition and cognition.
Sermorelin
Growth Hormone PeptideThe original growth hormone releasing peptide — gentler than direct GH, with decades of clinical history behind it.
Hexarelin
Growth Hormone PeptideThe most potent GH secretagogue peptide — delivers dramatic GH spikes but with a catch: rapid desensitisation.
GHRP-6
Growth Hormone PeptideThe 'hungry' GH peptide — potent growth hormone release paired with intense appetite stimulation. Popular but messy.
GHRP-2
Growth Hormone PeptideThe 'Goldilocks' GH secretagogue — stronger than Ipamorelin, cleaner than GHRP-6. The balanced middle ground.
Follistatin
Muscle & Performance PeptideThe myostatin blocker that unlocks muscle growth potential — the 'Belgian Blue' gene in a vial.
Epithalon
LongevityThe telomere-extending peptide from Russian gerontology. Anti-ageing at the chromosomal level.
SS-31 (Elamipretide)
Mitochondrial PeptideThe mitochondrial rescue peptide. Targets the powerhouse of the cell — literally.
GLP-1 Agonists (Overview)
Weight Loss & MetabolicThe drug class that changed obesity medicine forever. From Ozempic to Mounjaro — the full landscape.
Thymosin Alpha 1
Immune ModulationThe immune system conductor. Approved in 37 countries for hepatitis and cancer support. The West is just catching up.
CJC-1295 / Ipamorelin
Growth Hormone StackThe gold standard GH peptide combination. Synergistic growth hormone release with the cleanest side effect profile available.
