- Retatrutide 10 mg, batch PW-TG10-0626: the sample for the endotoxin test (Janoshik 216954) has a different cap colour than the sample for the content test (196738). This is not the same product, so the endotoxin result does not count.
- GHK-Cu 100 mg, batch PW-GHK100-0626: the sample for the endotoxin test (Janoshik 216956) has a different cap colour than the sample for the content test (208036). This is not the same product, so the endotoxin result does not count.
- Melanotan 2 10 mg, batch PW-MT210-0626: the sample for the endotoxin test (Janoshik 216957) has a different cap colour than the sample for the content test (200678). This is not the same product, so the endotoxin result does not count.
