Peptide Reference

Not technically peptides — SARMs (Selective Androgen Receptor Modulators) are small molecules that bind androgen receptors with tissue selectivity. Same page format as peptides. Note: most SARMs require post-cycle therapy (PCT) and carry meaningful suppression risk.

Ostarine MK-2866, Enobosarm

research mainstream oral

Mildest SARM — gentle muscle gain, joint healing, minimal suppression. The "starter" SARM.

Ligandrol LGD-4033

caution mainstream oral

Strongest mass-builder SARM — significant gains; higher suppression than Ostarine. PCT mandatory.

Testolone RAD-140

caution popular oral

Most "anabolic" SARM — near-steroid muscle gains; aggressive suppression and liver markers. Heavy hitter.

Andarine S-4

caution niche oral

Cutting-focused SARM — lean body recomposition. Notorious for yellow-tint vision side effect at higher doses.

YK-11 myostatin inhibitor

caution niche oral

Steroid-like myostatin inhibitor — not really a SARM. Liver-toxic; advanced users only.

S-23 "hardening" SARM

caution niche oral

Strongest binding SARM — lean, "dry" look but heavy suppression; once researched as a male contraceptive.

MK-677 Ibutamoren

research mainstream oral

Oral GH secretagogue — raises GH and IGF-1, improves sleep. Water retention and insulin resistance are common.

Cardarine GW-501516

caution popular oral

PPAR-delta agonist — massive endurance boost, fat loss. Cancer signal in long-duration rodent studies — controversial.

Stenabolic SR-9009

experimental niche oral

REV-ERB agonist — "exercise mimetic" effects, fat loss, endurance. Poor oral bioavailability — most users see weak effects.

Stacks for Goals

Common goal-driven combinations. Click any chip to jump to that compound's page. These are reference protocols, not personalized prescriptions — start with one new compound at a time so you can attribute effects.

Goal · Maximum fat loss

The Hard Cut

RetatrutideTriple agonist (GLP-1/GIP/glucagon) — most powerful fat-loss in trials, up to ~30% body weight reduction. TesamorelinGHRH analog targeting visceral belly fat — FDA-approved; widely used off-label for body recomp. AOD-9604HGH tail-fragment for stubborn fat — targets love handles and jawline; no growth-promoting effect.

Triple-receptor GLP/GIP/glucagon hits everything systemically; Tesamorelin removes visceral fat; AOD finishes stubborn subcutaneous areas.

Goal · Lean muscle gain

The Builder

CJC-1295Long-acting GHRH — extends GH pulse. The "C" in the classic CJC + Ipamorelin stack. IpamorelinCleanest GH-releaser — no cortisol/prolactin spike. Gold-standard GHRP for daily use. IGF-1 LR3Long-acting IGF-1 analog — the strongest mass-builder. Cancer-risk discussion is real; advanced users only.

CJC + Ipamorelin pulses GH cleanly; IGF-1 LR3 amplifies the downstream anabolic signal for hypertrophy.

Goal · Body recomposition

Cut Fat, Keep Muscle

TesamorelinGHRH analog targeting visceral belly fat — FDA-approved; widely used off-label for body recomp. IpamorelinCleanest GH-releaser — no cortisol/prolactin spike. Gold-standard GHRP for daily use. MOTS-cMitochondrial-derived peptide — nutrient partitioning, exercise-mimetic effects, sends calories to muscle not fat.

The classic "Tesa-IPA" blend drops fat while sparing lean tissue; MOTS-c improves nutrient partitioning so calories favor muscle.

Goal · Injury & tendon recovery

The Wolverine Stack

BPC-157The "Wolverine" peptide — tendon, gut, and soft tissue healing. The most-used recovery peptide globally. TB-500Pro-healing & angiogenesis peptide — soft-tissue recovery. Routinely paired with BPC-157.

BPC-157 drives tissue remodeling and gut healing; TB-500 promotes cell migration and angiogenesis. Run for 4–8 weeks around acute injuries.

Goal · Anti-aging & longevity

The Longevity Stack

EpitalonTelomerase activator — lengthens telomeres; resets melatonin via the pineal gland. Long-running Russian human trials. NAD+Mitochondrial energy + DNA repair cofactor — not technically a peptide, but the baseline for nearly every longevity stack. MOTS-cMitochondrial-derived peptide — nutrient partitioning, exercise-mimetic effects, sends calories to muscle not fat.

Epitalon supports telomeres and sleep architecture; NAD+ powers mitochondria; MOTS-c keeps cellular metabolism flexible.

Goal · Cognitive flow

The CEO Stack

SemaxBDNF-boosting nootropic — cleaner focus than Adderall, no crash. Russian clinical use for stroke and cognitive disorders. SelankGABA-modulating anxiolytic — mutes anxiety and overthinking without sedation. Pairs with Semax. NAD+Mitochondrial energy + DNA repair cofactor — not technically a peptide, but the baseline for nearly every longevity stack.

Semax raises BDNF for clean focus; Selank mutes anxiety without sedation; NAD+ provides the cellular energy floor.

Goal · Brain repair

Post-Burnout Reset

CerebrolysinPig-brain-derived neuropeptide blend — rebuilds brain after stroke, TBI, stimulant abuse. Approved in 50+ countries. NAD+Mitochondrial energy + DNA repair cofactor — not technically a peptide, but the baseline for nearly every longevity stack. DihexaStrongest known synaptogenic compound — ~7x stronger than BDNF. Promotes new synapse formation.

Cerebrolysin rebuilds neural tissue after stimulants/TBI/burnout; NAD+ supports cellular recovery; Dihexa promotes new synapse formation.

Goal · Skin & hair

The Glow Stack

GHK-CuCopper-binding tripeptide — collagen synthesis, hair, skin, and tendon repair. Most users overdose it. TB-500Pro-healing & angiogenesis peptide — soft-tissue recovery. Routinely paired with BPC-157. Melanotan IITanning + libido peptide — melanocortin agonist. Watch for mole darkening; get a baseline skin check.

GHK-Cu drives collagen and hair follicle health (low dose, evening); TB-500 supports skin turnover; Melanotan adds pigment without UV.

Goal · Sexual function

Libido & Performance

PT-141Melanocortin agonist for libido — works on the brain, not blood vessels. FDA-approved for female arousal disorder. OxytocinBonding hormone — social warmth, prosocial behavior, intimate connection. Used off-label intranasally. KisspeptinUpstream HPG-axis activator — raises both testosterone AND fertility, unlike TRT which suppresses both.

PT-141 acts centrally for arousal; Oxytocin enhances bonding and orgasm intensity; Kisspeptin supports the underlying hormone axis.

Goal · Testosterone (fertility-preserving)

Natural Test Boost

KisspeptinUpstream HPG-axis activator — raises both testosterone AND fertility, unlike TRT which suppresses both. HCGLH mimetic — preserves testicular function on TRT. The standard companion for thoughtful TRT protocols. EnclomipheneCleaner half of Clomid — nearly doubles natural testosterone without the mood/vision side effects. Preserves fertility.

Kisspeptin acts upstream; HCG mimics LH at the testicular level; Enclomiphene blocks estrogen feedback at the pituitary. All three preserve fertility, unlike straight TRT.

Goal · Sleep optimization

Deep Sleep Stack

DSIPSleep-promoting peptide — supports delta-wave (deep) sleep. Inconsistent reports in user community. EpitalonTelomerase activator — lengthens telomeres; resets melatonin via the pineal gland. Long-running Russian human trials.

DSIP supports delta-wave architecture night-of; Epitalon resets melatonin output via the pineal gland over a 10-day cycle.

Goal · Immune support

The Resilience Stack

Thymosin Alpha-1Immune-modulating peptide — restores T-cell function. Used clinically for hepatitis, sepsis, cancer adjunct. LL-37Antimicrobial peptide — broad-spectrum innate immunity. Direct kill activity against bacteria, viruses, fungi. LactoferrinIron-binding immune protein — antimicrobial, anti-inflammatory, gut-supportive. Available as supplement.

Thymosin Alpha-1 restores T-cell function; LL-37 provides direct antimicrobial activity; Lactoferrin handles gut-level immune defense.
