How they are different
- Identity on the lot CoA. BPC-157 is a 15-residue synthetic sequence. The lot CoA identifies the second peptide as Thymosin Beta-4, the parent protein behind the TB-500 research name. Some vendors sell a shorter fragment under the same name; that fragment is not what this vial's CoA reports. See the TB-500 reference.
- Mass and formula. BPC-157 has a published empirical formula and average mass. The lot CoA reports measured net content for Thymosin Beta-4 (9.78 mg) rather than a fragment formula.
- Lineage. TB-500 (Thymosin Beta-4) is named for a known natural protein. BPC-157 is a lab-synthetic peptide. See the glossary for term definitions.
How they are shared
In the Wolverine Blend research vial, both peptides are co-packaged as a lyophilized powder in the same sealed glass vial, in equal 10 mg amounts. See the Wolverine Blend specifications for presentation detail.
