Biotech peptides BPC-157: sizes, research and the blends

Biotech peptides BPC-157 comes in 5mg and 10mg vials and in two blends. Here is what the peptide is, what the studies looked at and which option fits your work.

What is biotech peptides BPC-157?

Biotech peptides BPC-157 is our listing for BPC-157, a chain of 15 amino acids cut from a larger protein first isolated from human gastric juice. BPC stands for body protection compound. Its sequence is Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, the CAS number is 137525-51-0 and the molecular weight is about 1419.5 g/mol.

It’s sold as freeze-dried powder, synthesized and lyophilized in the USA. The BPC-157 product page shows the lot’s certificate of analysis, the HPLC chromatogram and the mass spectrum for both sizes.

Biotech peptides BPC-157 prices and options

BPC-157 5mg: $52, about $10.40 per mg
BPC-157 10mg: $94, about $9.40 per mg
BPC-157 TB-500 Blend 10mg: $115
BPC-157 TB-500 GHK-Cu Blend 70mg: $305

The 10mg vial is the better price per milligram. The 5mg vial makes sense for a short pilot, since less solution sits in the fridge after mixing.

What the research on BPC-157 covers

Almost all of the published work comes from Predrag Sikiric’s group at the University of Zagreb, and almost all of it is in rodents. Their papers report faster healing of tendon, ligament, muscle and gut injuries, and they’ve tested the peptide both injected and by mouth, since it holds up unusually well in gastric juice.

A 2011 paper by Chang and colleagues found that BPC-157 raised growth hormone receptor levels in rat tendon cells, and other lab work points to blood vessel growth and the nitric oxide system. Controlled human data are very limited. You can read the papers on PubMed.

BPC-157 alone or in a blend?

BPC-157 is often studied next to TB-500, because the two reach repair through different routes. The BPC-157 TB-500 blend puts them in one 10mg vial, and the 70mg BPC-157 TB-500 GHK-Cu blend adds the copper peptide. If you want separate control groups, buy the single vials: TB-500 5mg, TB-500 10mg and GHK-Cu 50mg.

How much BPC-157 to order

Add up the total amount each group needs across every time point, then divide by the amount in one vial and round up. Add one spare vial for a repeat run or a lost dose. Buying everything at once keeps the whole study on one lot, which removes a variable you’d otherwise have to report. Keep unmixed vials frozen and reconstitute one at a time.

Designing a study around BPC-157

Most BPC-157 studies use a rodent injury model, such as a cut tendon, a muscle crush or a gut lesion, with an untreated group and a group given saline. Outcomes are usually measured by histology, biomechanical strength or how fast the lesion closes. If you plan to compare routes, the Zagreb papers used both injection and drinking water, which makes them a useful reference for your own design.

Storing biotech peptides BPC-157

Freeze the sealed vial at -20°C when it arrives. Reconstitute it with sterile bacteriostatic water, keep the solution at 2 to 8°C and use it within about four weeks. The product page for BPC-157 5mg / 10mg lists the concentration you get with 1mL, 2mL or 3mL of water.
