Structural Composition
BPC-157 (15-amino-acid synthetic peptide) + TB-500 (43-amino-acid Thymosin Beta-4 analog peptide)
Physical Properties
This blend combines BPC-157, a 15-amino-acid synthetic peptide, with TB-500, a 43-amino-acid Thymosin Beta-4 analog. Because the formulation contains two structurally distinct peptides, overall molecular formula and molecular weight are inherently variable and depend on blend ratios and hydration state. Lyophilized presentation supports storage stability, while protection from moisture, light, and repeated freeze–thaw cycles helps maintain structural integrity and analytical consistency for laboratory and research applications.

- Stability data suggests extended stability when stored at −20 °C or below.
Reconstituted Solution Storage
- Short-term storage: Up to 7 days at 4°C
- Long-term storage: Store at –20°C in aliquots
- Use single-use aliquots to preserve peptide integrity
- Minimize freeze–thaw cycles; single-use aliquots are strongly recommended
Stability Characteristics
BPC-157 + TB-500 Blend is a multi-component synthetic peptide research formulation. As a composite preparation, stability depends on proper cold storage of the lyophilized material, careful reconstitution, and minimized freeze–thaw exposure.

-
Short-term: 2–8 °C
Keep vials sealed and protected from light and moisture until use.
How should reconstituted blend solutions be handled and stored?
Once reconstituted:
-
Store at 2–8 °C for short-term laboratory use
-
For extended storage, aliquot and freeze at −20 °C or below
-
Minimize freeze–thaw cycles using single-use aliquots
-
Gently swirl to mix; avoid vigorous agitation
Does this blend require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch, verifying identity and purity for both peptide components within the blend to ensure research quality and traceability.
Is the BPC-157 + TB-500 blend FDA-approved?
No. This blend is not FDA-approved as a drug, supplement, or therapeutic product. It is sold exclusively as a research compound blend and must not be marketed or used for diagnostic, therapeutic, or consumption purposes.
