WADA Prohibited List
For athletes, BPC-157 and TB-500 are both on the 2026 WADA Prohibited List. BPC-157 is listed under S0 as an unapproved substance, and TB-500 under S2 by name. GHK-Cu is not on the list.
A blend containing prohibited substances is a prohibited blend
GLOW contains BPC-157 and TB-500, so for tested athletes, GLOW is a prohibited blend. Whether or not GHK-Cu is banned, the blend’s overall status is determined by its prohibited components.
Testing risk
WADA testing can identify BPC-157 and TB-500. Because both peptides are named on the 2026 list, testing agencies screen for them. Athletes using GLOW face a risk of a positive test.
Difference between S0 and S2
S0 covers any substance not approved for human use. BPC-157 falls here because it has not been approved in any country. S2 covers peptide hormones, growth factors, and related substances. TB-500 is explicitly listed under S2.
Why this matters
For professional athletes, a positive test can lead to suspension, loss of results, and reputational damage. Understanding GLOW’s WADA status is a necessary step before using any peptide product.
Conclusion
GLOW contains two WADA-prohibited components, making it banned for tested athletes. Before considering any peptide product, athletes should consult the latest WADA Prohibited List.
