BB (20mg)

BB pairs the two most-referenced tissue-repair peptides in the research literature — BPC-157 and TB-500, 10mg of each — in a single vial. The combination is so common in repair research that it has earned its own nickname: the "Wolverine" stack, a nod to how often the two appear side by side in studies of healing and regeneration models.

They are natural partners on the bench. BPC-157 is a stable, lab-made peptide based on a protective protein from the human stomach, studied for tissue-repair and cytoprotective signaling across many tissue types. TB-500 is built from the active region of Thymosin Beta-4, a natural protein the body uses to help cells move and organize during repair. One drives repair signaling; the other drives the cell movement repair depends on — which is exactly why labs study them together.

What researchers study it for:

• Tendon and ligament models — the most active shared area of study
• Wound-healing models — how quickly tissue closes and rebuilds
• Blood-vessel formation — new vessel growth during repair
• Inflammation signaling — how repair is dialed up and down

To be clear about the science: the evidence for both components is preclinical — cell and animal studies — and there are no completed human trials establishing what either compound, alone or combined, does in people.

BB is supplied as a lyophilized powder and reconstituted in the lab when a study calls for it. Every batch ships with a certificate tied to the specific lot, so the exact material behind a result is never in question.

Every batch is tested by an independent, accredited laboratory and ships with a batch-matched Certificate of Analysis (COA) you can look up before ordering — verified at 99% purity. For research use only. Not for human or animal consumption.
