GLOW
Not approvedBanned in sport
GLOW mixes 3 peptides into one product: BPC-157, TB-500 and GHK-Cu. It is KLOW without KPV. No published study has tested GLOW itself. What we know comes from studies of the 3 peptides, and almost all of those studies were in animals or lab cells.
Also known as GLOW blend, GLOW peptide, GLOW stack

Other blends with these peptides
KLOW is GLOW with KPV added. Wolverine has only BPC-157 and TB-500.
Some sellers use the name Wolverine for a mix of 4 peptides that also has CJC-1295 and ipamorelin.
Overview
Key points
- GLOW is a mix of 3 peptides: BPC-157, TB-500 and GHK-Cu.
- No published study has tested GLOW, in people or in animals.
- One rat study gave BPC-157 and TB-500 together. The pair worked no better than either peptide on its own.
- Most of the research behind GLOW is on BPC-157, and most of those studies used animals. TB-500 has no published results from people yet.
- GLOW is not an approved medicine. It is banned in sport, because it contains peptides that are banned.
- A draft US policy from October 2026 covers BPC-157 and TB-500 one at a time. Under it, HHS does not plan to act against licensed pharmacies that make them for a patient with a prescription. It does not cover blends like GLOW.

How much research each peptide has
BPC-157 has far more research than the other 2. All 3 bars use the same scale, so you can compare them.
What the 3 peptides were studied for
All 3 peptides were studied for skin and wound healing, for inflammation, and for muscles and tendons. Almost all of these results come from animals and lab cells.

Status and safety
Is GLOW approved?
No. GLOW is not an approved medicine, and none of the 3 peptides in it is an approved drug in the US.
| US FDA | Sport (WADA) | HHS draft policy | |
|---|---|---|---|
| BPC-157 | Not approved | BannedS0 | Covered on its own, with a prescription |
| TB-500 | Not approved | BannedS2 | Covered on its own, with a prescription |
| GHK-Cu | Not approved | BannedS0 | Not covered |
| GLOW itself | Not approved | BannedContains banned peptides | Not covered. The policy covers one peptide per product. |
HHS published a draft policy on October 30, 2026. Under it, HHS does not plan to act against licensed pharmacies or physicians that make BPC-157 or TB-500. Each product must be for a patient with a prescription, and strict conditions apply. The policy covers one peptide per product, so it does not cover blends like GLOW. It is a draft and gives no legal rights. Public comments are open until November 13, 2026.4
Is GLOW safe?
No study has checked whether GLOW is safe.
There is little safety data on the 3 peptides. BPC-157 has 24 safety results, including 8 from people. GHK-Cu has 5 and TB-500 has 1. Most come from lab cells and animals.
Quality also changes from product to product. A 2026 preprint looked at 6,441 lab tests of research peptides sold online, including BPC-157, TB-500 and GHK-Cu. Purity and the amount of peptide in each vial varied widely2.
Questions and more
Common questions
What is GLOW?
GLOW is a blend of 3 peptides in one product: BPC-157, TB-500 and GHK-Cu. It is not an approved medicine.
How is GLOW different from KLOW?
KLOW has the same 3 peptides plus KPV. No study has tested either blend, so no study shows what KPV adds to the mix.
Has GLOW been tested in people?
No. There are no published studies of GLOW in people or in animals. The closest is one rat study that gave 2 of its peptides, BPC-157 and TB-500, together.
Is GLOW banned in sport?
Yes. WADA bans BPC-157 and TB-500 by name. GHK-Cu is not named, but it falls under the WADA rule for unapproved substances. So the blend is banned too.
Can a US pharmacy make GLOW?
The HHS draft policy from October 2026 does not cover GLOW. It covers only one peptide per product, made for a patient with a prescription.
