And the term "copper peptides" itself is doing a lot of unearned work, because it lumps together GHK-Cu (the molecule with 50 years of evidence) with AHK-Cu, GHK-NH2, and a range of synthetic copper-binding sequences that have far thinner mechanism data
For instance, the relative levels of sphingosine 1-phosphate, phytosphingosine, sphinganine 1-phosphate, and 17a-estradiol were greatly decreased, whereas those of methyl jasmonate were distinctly increased in MS-affected patients compared with healthy subjects
These usually go away quickly
Your doctor may either assure you that your B level is fine (so no B needed), or they will arrange B shots in tandem if necessary
If you need samples for small-scale production, we will charge a sample cost first
