Compare chemical form, not only the name
A salt and its free base, two isomers or a metal complex are not necessarily the same material. Review the standard name, CAS, formula and molecular weight. In this catalog, GHK-Cu means Copper tripeptide-1 and should not be confused with copper-free GHK.
Read corrections and their limits
SRT2104 is listed with CAS 1093403-33-8; SymWhite 377 with CAS 85-27-8. TND-1128 and GW501516 retain their corrected codes. A source-based identity review identifies the reference record; it does not prove the composition of a received batch.
Prepare a verifiable inquiry
Share the record, specify the required form and request available batch information. Where identity confidence is provisional, retain that uncertainty rather than assuming equivalence with a similarly named material.
