Blends

About Blends

Blends combine two or more research peptides in a single lyophilized vial, with the total fill shown on the label and the components listed on each product page. Each vial is lot-numbered, with its Certificate of Analysis published in the COA library per lot; blends ship within the U.S. and are sold for laboratory research use only.

Current blends are BPC-157 + TB-500 (10 mg total, 5 mg + 5 mg; the combination is often called the Wolverine stack) and Klow, a four-peptide blend of GHK-Cu, BPC-157, TB-500 and KPV (80 mg total; the amount of each component will be listed with the lot's Certificate of Analysis). Renuvia Labs does not currently sell BPC-157 or TB-500 on its own.

Common questions about blends

What is a research blend?

Two or more peptides combined in one lyophilized vial at a stated ratio. The product page lists each component with the identifiers verified for it. Because a blend is a mixture, it has no single sequence, formula or CAS number of its own.

Has the blend itself been studied?

Usually not. The published research belongs to the individual components, and each product page says so plainly in its research profile and limitations. Our blend comparison pages set two blends side by side on composition and evidence.

How is a blend tested?

Lot testing is published in the COA library the same way as for single peptides; the report identifies the components present. A product shows "pending" until its current lot has a report.

How do blends fit volume pricing?

The same tiers apply: per-vial price drops automatically at 2, 3 and 5 vials of the same blend. Different products do not combine for the tier.
