GLOW is a three-peptide blend kept in a single vial and dosed together in one draw. The standard formulation is 70 mg total at a 50/10/10 ratio: 50 mg GHK-Cu, 10 mg BPC-157, and 10 mg TB-500 (TB-4). GHK-Cu is the lead compound at roughly 71% of vial mass; it's a copper-binding peptide studied largely in the context of skin and collagen-related research. BPC-157 and TB-500 sit alongside it at supporting proportions. GLOW is built around skin and aesthetic research goals, not soft-tissue injury work.
Because all three peptides share one vial at a fixed ratio, you don't dose them independently. You anchor on the lead compound (GHK-Cu) and the other two come along at their fixed proportion. A commonly referenced anchor in research contexts is around 2 mg GHK-Cu per dose, which puts BPC-157 and TB-500 at roughly 0.4 mg each per draw. Pick the GHK-Cu target that fits your protocol; the calculator above resolves what every component delivers at that anchor.
Reconstitution is where most of the friction is. Rather than guessing a water volume, choose the amount of bacteriostatic water that makes your GHK-Cu anchor land on a clean, easy-to-read syringe mark, a round number like 10, 20, or 50 units instead of an awkward 13 or 22. The calculator solves the BAC water volume for you and shows the per-component mass in each draw, so you can confirm the full blend before you reconstitute.
