GLOW FAQ: Your Questions Answered
The questions below are the ones that come up specifically about GLOW, rather than general peptide questions that apply to everything.
In plain English
The questions people actually ask: what is in it, why it is blue, whether it is mostly GHK-Cu, how to work out the strength of each part, and how it differs from KGLOW.
What GLOW actually is
GLOW is three well-known research compounds freeze-dried together in a single 70 mg vial: GHK-Cu at 50 mg, BPC-157 at 10 mg and TB-500 at 10 mg. Each is studied separately elsewhere, and each works through a different mechanism — collagen and skin matrix for GHK-Cu, blood vessel formation for BPC-157, cell movement for TB-500.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

GLOW — common questions
What is actually in GLOW?
Three components in a 70 mg vial: GHK-Cu at 50 mg, BPC-157 at 10 mg, and TB-500 at 10 mg. Each has its own substantial research literature, and each is available separately — GLOW combines them in one co-lyophilized preparation.
Why is GLOW blue?
Because GHK-Cu is 71% of the fill by mass, and the copper it coordinates produces the same blue seen in a pure GHK-Cu solution. This is genuinely useful: the colour tracks the integrity of the majority component, so a clear even blue is evidence the copper is still properly coordinated, while fading indicates it is not.
Is GLOW mostly GHK-Cu?
By mass it is 71% GHK-Cu. By molecule count it is roughly 94%, because GHK-Cu is a very small molecule (340 g/mol) while TB-500 is large (4963 g/mol). So 50 mg of GHK-Cu contains around 20 times as many molecules as 10 mg of BPC-157 and around 70 times as many as 10 mg of TB-500. The mass ratio substantially understates how dominant the copper peptide is.
How do I calculate concentration for GLOW?
The labelled 70 mg is total blend mass. Reconstituting in 3 mL gives roughly 23 mg/mL combined, which breaks down as approximately 16.7 mg/mL GHK-Cu and 3.3 mg/mL each of BPC-157 and TB-500. Because the ratio is fixed and known, per-component concentrations are straightforward to derive.
What is the difference between GLOW and KGLOW?
KGLOW adds a fourth component, KPV, at 10 mg — bringing the vial to 80 mg total. The GHK-Cu, BPC-157 and TB-500 amounts are identical in both. So KGLOW is GLOW plus KPV, not a different formulation.
Why can't I split a GLOW vial while it is still powder?
Three co-lyophilized components do not distribute homogeneously through a dry cake, so any physical division gives you an unknown ratio rather than 50:10:10. Reconstituting the whole vial and dividing the solution is the only way to preserve the intended proportions.
What GLOW is studied for
The majority component, with the deepest dermal literature — collagen and glycosaminoglycan synthesis in fibroblast models.
Studied around vessel formation and growth-factor pathways in tissue-repair models.
Actin sequestration and directed cell movement — how cells reach a tissue defect.
The three components act through genuinely non-overlapping mechanisms, which is the rationale for combining them.
