  • Snap-8 (Acetyl Octapeptide-3)
  • 0.1–0.5mg per site
  • 1–2mg/mL in bacteriostatic water
  • Daily to twice daily
  • 27–30G insulin syringe
  • 2–8°C, use within 28 days
  • Requires slow injection to prevent peptide shearing; do not massage post-injection
  • BPC-157
  • 250–500mcg per site
  • 1mg/mL in bacteriostatic water
  • Once or twice daily
  • 29–31G insulin syringe
  • 2–8°C, stable 60+ days
  • More stable than Snap-8; can tolerate brief temperature excursions
  • Matrixyl (Palmitoyl Pentapeptide)
  • 0.2–1mg per site
  • 2–5mg/mL in bacteriostatic water
  • Once daily
  • 2–8°C, use within 21 days
  • Higher concentration possible due to better solubility; similar injection technique
  • Copper Peptides (GHK-Cu)
  • 1–3mg per site
  • 5–10mg/mL in bacteriostatic water
  • 2–8°C, unstable beyond 14 days
  • Oxidizes rapidly; prepare in small batches
  • Snap-8's acetyl modification improves skin penetration but reduces stability compared to non-acetylated peptides. Researchers using Snap-8 subcutaneously report better consistency with daily fresh-draw protocol. Preparing syringes in advance increases degradation risk even under refrigeration.
