Use a syringe with clear mL markings, not guesswork
Fasted administration is critical because the peptide works by stimulating lipolysis (fat breakdown) through beta-3 adrenergic receptor activation
If your goal is skin firmness, fine lines, or hair thinning, this is the right route

Skin wound healing: acute wounds, slow-healing wounds, and post-traumatic skin repair where collagen remodeling is a clinical priority Post-surgical tissue recovery: skin and soft tissue healing following surgical procedures, particularly where scar minimization and organized collagen deposition are desired Anti-aging and skin rejuvenation: wrinkle reduction, skin firmness, and surface texture improvement through topical or injectable GHK-Cu protocols Hair follicle stimulation: investigated for hair growth support in patients with hair thinning or loss where scalp vascularity and follicle reactivation are clinical targets Gastrointestinal mucosal healing: investigated for ulcerative colitis and GI mucosal repair through SIRT1/STAT3 pathway inhibition Combination wound healing protocols: used alongside BPC-157 and TB-500 to provide copper-dependent enzyme activation and gene expression regulation as part of a comprehensive tissue repair approach GHK-Cu is the peptide most commonly associated with skin applications in physician-supervised peptide therapy, and it occupies a distinct clinical role from the musculoskeletal-focused BPC-157 and TB-500

Intranasal administration may be an excellent approach for certain therapeutic effects
BPC 157 also acts as a free radical scavenger, counteracts free radical-induced lesions, and normalizes NO and MDA levels in tissues and during ischemia and reperfusion
