## Description

The two peptides most frequently combined in soft-tissue repair studies, BPC-157 and TB-500, are supplied here as one pre-mixed aqueous solution in an amber bottle with a metered nasal pump, in 15 mL and 30 mL sizes. Each active is synthesised and purified on its own to ≥99% by reversed-phase HPLC before both go into a single bulk solution — so the certificate of analysis reports each peptide individually instead of characterising the blend as one.

BPC-157 is a 15-residue partial sequence of a protein found in human gastric juice and stands out among research peptides for being relatively stable in water. TB-500 is the acetylated seven-residue fragment matching residues 17–23 of thymosin beta-4 — the actin-binding region of a 43-amino-acid protein that sequesters G-actin. They are investigated together because they are thought to act through separate pathways: BPC-157 has been studied in connection with nitric oxide signalling and growth-factor receptor expression, TB-500 mainly for actin dynamics and cell migration.

## Frequently asked questions

### In what ratio are BPC-157 and TB-500 present?

The bulk solution is made to a fixed nominal ratio; the exact amount of each peptide is printed on the bottle label and restated on the lot's certificate of analysis. Both sizes are filled from the same bulk, so the 15 mL and 30 mL bottles have the same concentration and differ only in volume.

### Are the peptides the same as those in your lyophilised vials?

Yes — the same BPC-157 and TB-500 of ≥99% HPLC purity, with matching CAS numbers, formulas and sequences. They simply arrive pre-dissolved in a metered nasal pump rather than as powders you reconstitute.

### Is a certificate of analysis included?

Each bottle traces back to a COA covering both peptides in its fill: HPLC purity of ≥99% for each component, plus identity by mass spectrometry, with the two reported separately. Please quote the lot number on the label when requesting it.

### How long does the solution remain usable after opening?

That depends on how carefully it is stored and on the study period you set. Keeping it cold, dark and upright slows hydrolysis and oxidation, but any solution is less stable than a lyophilised cake. For studies lasting several weeks, check the concentration analytically rather than relying on the labelled value.
