- TB-500
- Thymosin Beta-4 mimetic. Upregulates actin polymerization and cellular migration
- Cardiovascular, skeletal muscle, tendons, neurological tissue, wound beds
- 2.5–3 hours (synthetic acetate form)
- Best for systemic tissue remodeling and conditions requiring cellular migration. Cardiac repair, chronic tendinopathy, neurological recovery
- BPC-157
- VEGF upregulation, nitric oxide modulation, FAK-paxillin pathway activation
- Tendons, ligaments, gastric mucosa, localized muscle injuries
- 4–6 hours (estimated. Limited human pharmacokinetic data)
- Best for acute localized injuries requiring rapid angiogenesis and inflammation control. Torn ligaments, gastric ulcers, localized muscle tears
- GHK-Cu
- Gene expression modulation (collagen upregulation, inflammation downregulation), copper-dependent enzyme activation
- Skin, hair follicles, dermal connective tissue, wound margins
- 1–2 hours
- Best for skin repair, scar reduction, and tissue remodeling where collagen quality matters more than cellular migration
- GHRP-2
- Growth hormone secretagogue. Binds GHS-R1a receptors in pituitary
- Systemic (muscle, bone, metabolic tissue)
- 30–45 minutes
- Best for systemic anabolic effects and GH-dependent tissue growth. Not a direct tissue repair agent like TB-500
- Ipamorelin
- Selective GH secretagogue. Minimal ACTH or cortisol elevation
- Systemic (muscle, bone, fat metabolism)
- 2 hours
- Best for lean mass retention and GH elevation without cortisol spikes. Indirect tissue support, not direct regeneration
- Sermorelin
- GHRH analog. Stimulates endogenous GH pulse frequency
- Systemic (metabolic tissue, sleep architecture)
- 10–20 minutes
- Best for restoring natural GH pulsatility in age-related decline. Supports tissue health systemically but not injury-specific repair
