How Glow is supplied
Glow is supplied as a Pre-filled pen graduated in dial units, so no reconstitution arithmetic is required. Reported half-life: Differs per constituent: GHK-Cu and glutathione are short in circulation, BPC-157 likewise. Storage: Refrigerated, protected from light. The copper component gives solutions a blue tint, which is expected.

Why presentation changes the comparison
Cost per milligram is calculated from the strength printed on the listing. Where a listing states no strength the column is left blank rather than estimated. Two Glow listings at the same headline price are not comparable if one is a lyophilised vial and the other a pen already in solution.
