glow stack FAQ

No. Glow Stack is supplied as a pre-mixed lyophilized formulation with fixed peptide ratios optimized for multi-pathway research. If your protocol requires independent dose titration of GHK-Cu, glutathione, and collagen peptides, purchase them as separate products from Real Peptides' full collection. This allows you to reconstitute each peptide at the concentration your experimental design requires and combine them in custom ratios. Stacks sacrifice dosing flexibility for convenience and reproducibility. Choose based on whether your research prioritizes mechanistic control or ecological modeling.
