Fat Loss & Metabolism

// ranked by raw weight-loss efficacy in trials
Retatrutide "the Hard R"
research mainstream subQ
Triple agonist (GLP-1 / GIP / glucagon) — the most powerful fat-loss compound currently in trials, up to ~30% body weight reduction.
Tirzepatide Mounjaro, Zepbound
FDA-approved mainstream subQ
Dual GLP-1 / GIP agonist — outperforms semaglutide on weight loss (~22%) and metabolic markers.
Survodutide BI 456906
experimental cutting-edge subQ
Dual GLP-1/glucagon agonist — ~19% body weight loss in Phase 2. Boehringer Ingelheim.
Mazdutide IBI362 · approved in China
approved (China) cutting-edge subQ
Dual GLP-1/glucagon agonist — ~16% weight loss; China-approved 2025; pending US/EU.
Semaglutide Ozempic, Wegovy
FDA-approved mainstream subQ
GLP-1 agonist — most prescribed weight-loss drug; 15–20% body weight reduction. Beware muscle loss without resistance training.
Tesamorelin Egrifta
FDA-approved popular subQ
GHRH analog targeting visceral belly fat — FDA-approved for HIV lipodystrophy; widely used off-label for body recomp.
Cotadutide MEDI0382
experimental cutting-edge subQ
Dual GLP-1/glucagon agonist — AstraZeneca investigational. Strong liver fat reduction in trials.
Tesofensine NS2330
caution niche oral
Monoamine reuptake inhibitor — appetite suppression + cognitive lift. Cardiovascular caution. Approved in Mexico.
Liraglutide Saxenda, Victoza
FDA-approved popular subQ
Daily-injection GLP-1 agonist — older sibling to semaglutide. Less weight loss, faster onset, more flexibility.
Dulaglutide Trulicity
FDA-approved popular subQ
Weekly GLP-1 for type 2 diabetes — modest weight loss; primarily a glucose-control drug.
AOD-9604 HGH fragment
research popular subQ
HGH tail-fragment for stubborn fat — targets love handles and jawline; no growth-promoting effect.
HGH Frag 176-191 growth hormone fragment
research niche subQ
HGH C-terminal fragment — pure lipolysis, no IGF-1 effects, no insulin sensitivity issues like full HGH.
MOTS-c mitochondrial peptide
research popular subQ
Mitochondrial-derived peptide — nutrient partitioning, exercise-mimetic effects, sends calories to muscle not fat.
5-Amino-1MQ NNMT inhibitor
experimental cutting-edge oral
"Exercise in a bottle" — raises NAD+, boosts metabolic flexibility, supports fat loss without appetite suppression.
Adipotide FTPP · prohibitin-targeting
caution niche subQ
Targeted fat-vasculature destruction — experimental. Renal toxicity in primate trials limits real-world use.

Muscle & Growth Hormone

// ranked by anabolic potency
HGH / Somatropin Norditropin · Genotropin
FDA-approved mainstream subQ
Recombinant human growth hormone — the actual GH molecule. Bypasses pituitary; suppresses natural production.
IGF-1 LR3 long-acting IGF-1
caution popular subQ
Long-acting IGF-1 analog — the strongest mass-builder. Cancer-risk discussion is real; advanced users only.
IGF-1 DES site-specific IGF
caution niche subQ
Short-acting IGF-1 variant — injected into specific muscles for localized hypertrophy. Niche bodybuilding tool.
CJC-1295 Modified GRF 1-29
research mainstream subQ
Long-acting GHRH — extends GH pulse. The "C" in the classic CJC + Ipamorelin stack.
Ipamorelin selective GHRP
well-tolerated mainstream subQ
Cleanest GH-releaser — no cortisol/prolactin spike. The gold-standard GHRP for daily use.
Hexarelin GHRP-6 analog
research niche subQ
Strong GHRP with cardioprotective effects — tachyphylaxis (tolerance) is a real issue with extended use.
Sermorelin GHRH analog
FDA-approved popular subQ
The gentlest GH-releaser — best entry point for beginners. Improves sleep, recovery, body composition over months.
GHRP-2 growth hormone releaser
research niche subQ
Older-generation GHRP — modest cortisol/prolactin spike; mostly superseded by Ipamorelin.
GHRP-6 appetite-stimulating GHRP
research niche subQ
GHRP with strong hunger effect — useful for hard-gainers needing appetite boost.
PEG-MGF PEGylated MGF
experimental niche subQ
Long-acting MGF — satellite cell activation for hypertrophy. Theory strong, real-world results inconsistent.
MGF mechano growth factor
experimental niche subQ
Splice variant of IGF-1 — fires after muscle damage to recruit satellite cells.

SARMs & Related Compounds

9 compounds

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

Goal · Injury & tendon recovery
The Wolverine Stack
BPC-157 drives tissue remodeling and gut healing; TB-500 promotes cell migration and angiogenesis. Run for 4–8 weeks around acute injuries.
Goal · Testosterone (fertility-preserving)
Natural Test Boost
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
DSIP supports delta-wave architecture night-of; Epitalon resets melatonin output via the pineal gland over a 10-day cycle.
Goal · Post-Cycle Therapy (PCT)
HPG Axis Restart
After a SARM or steroid cycle, HCG restores testicular function, Enclomiphene unblocks pituitary feedback, and a single Triptorelin shot resets the entire HPG axis. Run 4–6 weeks post-cycle.
Goal · Hangover / party recovery
The Recovery Reset
NAD+ restores cellular energy after alcohol/stimulant load; Glutathione (oral, not on this site) neutralizes free radicals; Selank kills the post-binge anxiety; Semax restores verbal sharpness.
Goal · Hair regrowth
The Follicle Stack
GHK-Cu drives follicle activity and collagen at the scalp (low dose); TB-500 supports cell migration and angiogenesis; Tesamorelin's GH/IGF-1 boost supports follicle growth phases. Pair with topical minoxidil for synergy.
