- Reported half-life differs: GHK-Cu at ~5-10 minutes versus SNAP-8 at ~1-2 hours.
- Primary molecular target differs: GHK-Cu acts on Extracellular matrix remodeling via MMP/TIMP balance; TGF-beta modulation; antioxidant enzyme (SOD, catalase) upregulation; VEGF and FGF stimulation; SNAP-8 acts on SNAP-25 (synaptosomal-associated protein 25); competes for SNARE complex assembly; reduces acetylcholine vesicle fusion at neuromuscular junction.
