GLOW Blend: literature-reported ranges

GLOW is a commercial three-peptide blend. No study has tested this combination, and one of its components — GHK-Cu — has a literature that is almost entirely topical, which makes its inclusion in an injectable blend a question worth asking.

Read this first

Every figure on this page is a range reported in published literature or in a publicly documented study protocol. It is a record of what researchers used, not a recommendation, a therapeutic protocol, or advice. Peptide Intel Hub is an independent publication, sells nothing, and describes these compounds as in-vitro research reagents only.

What the published studies reported

Each row below describes one body of work. The model and population are part of the figure — a rodent per-kilogram quantity and a human trial quantity are not comparable.

Constituent literature, read separately

Reported quantity
GHK-Cu 0.05–2% topical; BPC-157 10 µg/kg rodent; TB-500 (as TB4) 1–10 mg/kg rodent
Frequency
As reported in each separate literature
Study duration
8–12 weeks (GHK-Cu topical); 10–28 days (rodent repair models)

There is no published route or timescale under which all three of these figures apply together.

No peer-reviewed study of GHK-Cu + BPC-157 + TB-500 in combination has been indexed.

Mixed with 3 ml of bacteriostatic water

The same arithmetic for every vial size GLOW Blend is supplied in, using a fixed 3 ml of bacteriostatic water. One unit on a U-100 insulin syringe is 0.01 ml, so the unit column below is simply the volume that carries the reported amount. Educational arithmetic only — not instructions, and not medical advice.

No single reported amount applies to this compound, so only the concentration and the value of one unit are shown. Only the vial sizes this compound is actually supplied in are shown, and every figure assumes exactly 3 ml of bacteriostatic water. For any other volume, use the reconstitution calculator.

Reconstitution maths

Blend vials commonly state a combined mass such as 70 mg. Only a per-peptide breakdown on the certificate tells you what is in it; the copper complex should also be confirmed separately.

How to read these figures

  • GHK-Cu's evidence base is topical dermatology; injectable use is an extrapolation, not a reading of the literature.
  • Three peptides means three identity assays and three stability profiles in one solution.
  • Copper-containing solutions in a mixed vial raise compatibility questions no manufacturer has published data on.

No peer-reviewed primary literature reporting administered quantities exists for this item. Anything circulating online about quantities is anecdote rather than evidence, and this page will not reproduce it. The database links below are kept so you can check for yourself as new work is published.

Independent publication — we sell nothing. Supplier disclosure

Peptide Intel Hub is an independent educational publication. We are not affiliated with, owned by, or the same company as Regena Peptides and Regena.app (regena-peptides.com / regena.app). We do not sell, supply, ship or take payment for any compound. Because readers regularly ask where compounds discussed in published studies can be sourced for laboratory work, we list Regena Peptides and Regena.app as suppliers we have verified and trust — every batch is released with a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
