Peptide Blends UK — What a Blend COA Must Show
A blend COA must show more than a single purity figure. For a documented blend, the certificate has to identify each peptide and report purity for each — on the same record as the lot you receive.

Why blends complicate verification
A single-compound certificate reports one purity and one identity. A blend has several compounds in one vial, so a single purity figure tells you almost nothing — you need each component identified and quantified on the same record, tied to the same lot number.
What a blend COA must show
For each peptide in the blend: identity confirmation and its purity/content on the same certificate, plus the batch or lot number that matches the vial. If the certificate lists only one compound, or one aggregate number, the record is not complete.
How Index Peptides documents blends
The BPC-157 + TB-500 blend (20mg) and the GHK-Cu + BPC-157 + TB-500 blend (70mg) each carry their own batch record with per-peptide documentation, published on the product page and checkable by lot number on the verify page.
Blends as a format
A documented blend is a valid research format; the requirement is that the documentation matches the complexity of the vial.
How to order
Both blends are listed with their batch records on the product pages. Order online or request an invoice. Research use only.
Frequently asked questions
Why isn't a single purity figure enough for a blend?
A blend contains multiple compounds; one aggregate figure cannot tell you what is in the vial. Each peptide needs its own identity confirmation and purity/content on the same certificate.
Can I check a blend by lot number?
Yes — every released Index Peptides blend batch is checkable by its lot number on the verify page, with the per-peptide record.
Which blends does Index Peptides supply?
A BPC-157 + TB-500 blend (20mg) and a three-way blend of GHK-Cu, BPC-157 and TB-500 (70mg), each with its own published batch record.
