BPC-157 and TB-500 Research Stack
BPC157 and TB500 are the most commonly paired tissue-repair research peptides, often listed together as the Wolverine stack. This page explains how the two sequences differ, why research protocols pair them, and how each lot is documented at Amino Fuel Labs.
Two different repair pathways
BPC-157 is a synthetic 15-amino-acid sequence derived from a gastric protective protein and is referenced in tendon, ligament, and gastrointestinal research models. TB-500 is a synthetic fragment of thymosin beta-4 and is referenced in soft tissue, dermal, and cardiac research models through actin-binding mechanisms. Because the mechanisms described in the literature differ, protocols that study general tissue repair often include both.
How the pair is typically supplied
Amino Fuel Labs supplies BPC-157 and TB-500 as separate lyophilized vials rather than a pre-mixed blend, so each compound can be reconstituted and dosed independently in a research design. Add each vial to the cart separately; there is no single combined SKU.
Purity documentation for both vials
Each lot of BPC-157 and TB-500 is verified by reverse-phase HPLC at a third-party analytical laboratory. Certificates of Analysis list identity, lot number, manufacture and retest dates, appearance, and measured purity, and the vial label lot always matches the COA.
Storage and reconstitution
Both peptides ship lyophilized and are stored per COA guidance. Reconstitution with bacteriostatic water follows your own laboratory protocol; our reconstitution calculator helps convert vial mass to working concentration. All material is sold for laboratory research only and is not for human consumption.

Frequently asked questions
What is the BPC-157 and TB-500 stack?
Two separate research peptides — BPC-157 and TB-500 — studied together in tissue repair research models. They are supplied as individual vials, not a pre-mixed blend.
Are BPC157 and TB500 sold as one product?
No. Each is a separate catalog item and must be added to the cart individually.
Are both peptides lab tested?
Yes — third-party reverse-phase HPLC per lot, COA included.
How are they reconstituted?
Each vial is reconstituted separately with bacteriostatic water per your laboratory protocol.
Is this for research use only?
Yes — not for human consumption.
