TRACKER 6 OCT 2026 · WADA publishes the 2027 Prohibited List, in force January 1, 2027. What changed

GLOW

Three-peptide blend: BPC-157, TB-500 and GHK-Cu. Also sold as "GLOW blend", "GLOW stack"
FDA: not approved WADA: contains 2 prohibited substances No human trial of the blend
STATUS AS OF
BPC-157 · FDA: not FDA-approved for any use · 503A: not on the 503A bulks list. FDA advisers recommended it on July 23, 2026; the vote is non-binding and no rule has been proposed · WADA: prohibited at all times under the 2026 WADA List (S0, non-approved substances) · tracker entry
TB-500 · FDA: not FDA-approved for any use · 503A: not on the 503A bulks list. FDA advisers recommended it on July 23, 2026; the vote is non-binding and no rule has been proposed · WADA: prohibited at all times under the 2026 WADA List (S2.3: thymosin beta-4 and its derivatives, e.g. TB-500) · tracker entry
GHK-Cu · FDA: legal as a cosmetic ingredient; not FDA-approved as a drug · 503A: injectable form off Category 2 since April 15, 2026 but not eligible for compounding; FDA advisers are due to review it before the end of February 2027 · WADA: not named on the 2026 WADA List. Because it is unapproved, the catch-all S0 section may still apply; ask USADA before use · tracker entry

The short answer: GLOW is an unapproved three-peptide blend of BPC-157, TB-500 and GHK-Cu, and as of October 17, 2026 the combination has not been tested in a published human trial. Its skin claims borrow from studies of copper peptide creams, not injections, and two of its three ingredients are banned in sport at all times.

What is in GLOW?

GLOW is a blend of BPC-157, TB-500 and GHK-Cu sold together. Clinics and sellers market it for skin and recovery. Adding KPV to the same three gives the blend sold as KLOW.

Note: We don't list amounts. Sellers mix these peptides in different proportions and often don't publish them. Why we don't publish doses or ratios

Does GLOW work for skin? Topical vs injected GHK-Cu

GLOW's skin claims rest on GHK-Cu. As a cream, copper peptide has decades of small human cosmetic studies, mostly funded by industry. Injected GHK-Cu has no published human data, and GLOW is sold as an injectable blend. A result for a cream does not transfer to an injection.

What sellers claim vs what has been shown

ClaimedShown
Glowing, firmer skin Small human studies of copper peptide creams. Not shown for injected GHK-Cu or for GLOW.[1,7]
Faster recovery In rodents, for BPC-157 and thymosin beta-4. Not tested for the blend.[2,3]

What we don't know
  • Whether injected GHK-Cu does anything for skin in people.
  • Whether the three peptides interact or stay stable when mixed.
  • What is actually in products sold online.
Why this page has no dosing We don't publish doses, schedules or mixing instructions for GLOW or any unapproved peptide. No human dose has been established for most of these uses, so we list what to ask a licensed prescriber instead. Here's why, and who can legally answer
Get medical help now if you have
  • Swelling of the face, lips or throat, trouble breathing, chest pain, a racing heart or fainting. Call 911.
  • Redness spreading from an injection site, warmth, pus or a fever. Get same-day care.
  • Unsure what you took or whether a reaction is serious: Poison Control 1-800-222-1222 (free, 24 hours).
  • Thoughts of harming yourself: call or text 988.
Who should be especially careful
  • If you are pregnant, trying to get pregnant or breastfeeding. There is no human data on any of these ingredients in pregnancy.
  • If you have or have had cancer. BPC-157 and thymosin beta-4 have a theoretical blood-vessel growth concern.
  • If you compete in tested sport or serve in the military. GLOW contains two substances prohibited at all times.
  • If you have liver disease or a copper-related condition. GHK-Cu adds copper.
