Hereโs a quick reference guide to almost all of the popular peptides within the researcher/biohacking sphere:
REPAIR, RECOVERY & AGING:
- BPC-157 โ gut lining, healing injuries, tissue repair
- TB-500 โ cuts down inflammation, helps muscle repair and flexibility
- GHK-Cu โ skin repair, collagen, wound healing, hair benefits
- KPV โ calms gut irritation and supports immune balance
- Epithalon โ circadian rhythm, cellular cleanup, healthier aging
- NAD+ โ powers brain cells, boosts energy, longevity angle
- Glutathione โ detox, immunity, skin clarity
- Thymosin Alpha-1 โ helps regulate immune response and inflammation
- SS-31 โ protects mitochondria, cell energy, anti-aging
BODY RECOMP, POWER & RECOVERY (GH/IGF AXIS):
- Ipamorelin โ GH release, deep sleep, healing, mild and clean
- CJC-1295 + Ipamorelin โ the classic GH stack for recovery and fat loss
- IGF-1 LR3 โ systemic tissue repair and muscle growth, not for beginners
- HGH โ the standard for recovery, body recomp, sleep, anti-aging
WEIGHT LOSS & METABOLIC HEALTH:
- Semaglutide โ kills appetite, drives weight loss, improves blood sugar, strongest human data here
- Tirzepatide โ dual pathway for appetite, fat loss, insulin function
- Retatrutide โ triple pathway, early buzz for aggressive fat loss, still research only
- Tesamorelin โ specifically attacks belly fat, FDA context exists
- Cagrilintide โ appetite suppression via amylin pathway
- AOD-9604 โ fat targeting, but FDA has flagged safety concerns with limited data
- HGH Fragment 176-191 โ fat burning while holding onto muscle, mostly animal studies
- 5-Amino-1MQ โ NNMT inhibition for metabolism, human data scarce
- MOTS-c โ mitochondrial energy and fat burning, experimental
BRAIN, MOOD & SLEEP:
- Semax โ sharp focus, memory lift, mood, mental energy, can feel stimulating
-Selank โ chills anxiety, improves mood, calm focus, often paired with Semax
- DSIP โ helps with sleep quality and calming the nervous system
- Epithalon โ also used here for sleep cycle support (see longevity)
- Dihexa โ cognitive boost, highly experimental, not for casual use
- Kisspeptin-10 โ mood, libido, hormone signaling
SKIN, HAIR & LOOKS:
- GHK-Cu โ injectable or topical for collagen, texture, wound healing, hair
- Melanotan II โ tanning without sun plus libido boost, watch for nausea and mole changes
SEX & LIBIDO:
- PT-141 โ works on the brain's arousal centers (not vascular), FDA version exists for women
- Melanotan II โ tanning first, libido second
- Oxytocin โ bonding, closeness, mood, effects aren't consistent for everyone
- Kisspeptin-10 โ libido and upstream hormone signaling
GUT & SYSTEMIC INFLAMMATION:
- BPC-157 โ repairs gut lining, digestive support, lowers inflammation
- KPV โ GI-specific and general inflammatory conditions
- Glutathione โ detox and immune support (listed above, but fits here too)
- LL-37 โ antimicrobial and immune defense, very limited human work
POPULAR STACKS:
- Wolverine (BPC + TB-500) โ soft tissue and recovery
- GLOW โ BPC + TB + GHK-Cu for skin, hair, and healing
- KLOW โ GLOW + KPV adds gut and inflammation coverage
- CJC + Ipamorelin โ the go-to GH support stack
TRT & HORMONE MANAGEMENT:
- Test C / Test E โ standard TRT bases
- HCG โ keeps fertility and testicular function alive on TRT
- Enclomiphene โ SERM that raises natural testosterone without shutting you down
Hope this helps some of you with your research and maybe where to get started. Almost all of these peptides are research chemicals only (with regards to a few on this list). Do your due diligence when conducting peptides research!
