Storing Glow 70mg: Best Practices

Lyophilized Powder: Store at -20°C for long-term stability (up to 24 months). White-to-pale-blue powder; the faint blue tint reflects the GHK-Cu copper complex (50 mg fraction). Hygroscopic — keep tightly sealed under inert gas (N₂ or Argon).

Reconstituted Solution: Store aliquots at -80°C for up to 6 months. Refrigerated (2–8°C) solutions should be used within 14 days due to BPC-157 and TB-500 hydrolysis kinetics. Reconstitute with bacteriostatic water or sterile saline using gentle swirling — do not vortex or shake aggressively.

pH Stability: Stable in the range of pH 5.0–7.0. Below pH 4 or above pH 9, GHK-Cu may dissociate and release free copper, which can catalyze oxidative degradation of BPC-157 and TB-500.

Critical Incompatibilities: Do not co-formulate with EDTA, carnosine, Vitamin C, or other strong chelators — these strip Cu(II) from GHK-Cu and abolish its activity.

Component Purity: ≥98% per peptide by HPLC; identity by mass spectrometry; TFA-free preferred for biological-grade research.

Handling: Allow vials to warm to room temperature before opening to prevent moisture condensation onto the lyophilized cake. Standard aseptic technique. Discard any solution that appears cloudy or contains particulate matter.
