whatpeptidestostackGHK-Cu and TB-500
Co-administeredTwo peptides discussed for wound healing. One early human pilot put both in the same multi-ingredient formula, which is not the same as testing the pair.
How the two mechanisms relate
This part is our reading of the mechanism. The grade above is what the published record shows.
What this pairing does and does not show
"Co-administered" means something narrow here. One early human pilot put GHK-Cu and TB-500 in the same multi-ingredient formula. So both were given, but the design can't tell what either peptide did, or whether the pair adds anything.
It shows both were used. It doesn't test the pair.
There's a TB-500 catch too: the one human randomized trial in its record used the full parent peptide, thymosin beta-4, not the fragment. GHK-Cu has the stronger human result of the two, an older randomized ulcer study.
Our grade definitions explain the three grades, and BPC-157 and GHK-Cu shows a lower grade for comparison.
The compounds
GHK-Cu
A naturally occurring copper peptide studied mostly for skin remodeling and wound healing. Its strongest human result is an older randomized ulcer study.
Full profile, dosing and safety →TB-500
A short fragment of thymosin beta-4. Almost all outcome data are animal or laboratory, and the one human randomized trial used the full parent peptide, not the fragment.
