Weight Loss & Fat Loss7 compounds GLP-1/GIP/glucagon-based compounds like Retatrutide and Mazdutide work through appetite suppression, improved insulin sensitivity, and increased energy expenditure. Amylin-based Cagrilintide targets satiety through a different mechanism, while AOD-9604 and 5-Amino-1MQ focus more directly on fat metabolism, and Tesofensine and SLU-PP-332 take distinct neurological and mitochondrial approaches.
Muscle Growth & Performance7 compounds Growth hormone releasing peptides that stimulate natural growth hormone production typically support muscle building goals. CJC-1295 combined with Ipamorelin represents a popular approach for enhancing muscle growth, recovery, and body composition over time. IGF-1 LR3 and FLGR-242 work further downstream on direct growth signaling, while HGH is direct hormone replacement rather than a signaling peptide.
Injury Recovery & Healing8 compounds The peptides most studied for injury recovery and healing are BPC-157 and TB-500, researched for tendon, ligament and soft-tissue repair, alongside GHK-Cu for tissue remodeling, KPV and Thymosin Alpha-1 for inflammation and immune coordination, ARA-290 for nerve-related recovery, Cartalax for joint and cartilage support, and MGF for early-phase muscle-damage signaling.
Anti-Aging & Longevity5 compounds Anti-aging approaches using peptides focus on supporting natural processes that decline with age — Epitalon for cellular aging and circadian regulation, MOTS-C and SS-31 for mitochondrial function, NAD+ as a foundational cellular-energy compound, and Klotho for vascular and cognitive longevity research.
Skin, Hair & Beauty4 compounds Skin quality improvement may be supported by peptides that stimulate collagen production, such as GHK-Cu, or influence melanin production for tanning research, such as Melanotan I and II. Glutathione is researched more broadly for antioxidant and skin-clarity support.
Cognition, Focus & Mood6 compounds Cognitive function support is an emerging area of peptide research. Semax and Selank are researched for focus and calm-focus respectively, Cerebrolysin and Pinealon for neurotrophic and neuroprotective support, and Dihexa and Methylene Blue for structural and mitochondrial approaches to cognition.
Sexual Health & Libido4 compounds Sexual health research spans PT-141, a melanocortin-pathway compound researched for libido in both sexes, along with hormonal-support peptides Kisspeptin and HCG investigated for HPTA function and fertility, and Oxytocin for bonding and connection.
Immune Support3 compounds Immune system support can be addressed through peptides that enhance immune coordination, such as Thymosin Alpha-1, direct antimicrobial action, such as LL-37, or respiratory-tissue-specific bioregulators, such as Bronchogen.
