Absolutely! Every batch gets a verified coa clearly listed with each associated product. We carefully select and only work with the highest quality ingredients/products. Each batch is laboratory tested for purity. All the Certificates of Analysis (COAs) available on our website provide details about the purity and potency of the peptides, expressed in milligrams (mg) or mcg’s. Please note that this reflects the strength of the products, not their physical weight.

Additionally, the batch numbers listed on the COAs correspond directly to the batch numbers on the peptide vials, ensuring accuracy and traceability.
