BPC-157 FAQ: Reconstitution, Storage, Purity & Sourcing

3 min read•Published 2025-07-25•Quality Peptide USA Research

BPC-157 (Body Protection Compound 157) is a stable synthetic pentadecapeptide originally derived from a protective protein identified in gastric juice. It is one of the most heavily studied research peptides in the soft-tissue and gastrointestinal literature. This guide covers faq for researchers for BPC-157 — written for laboratory researchers sourcing US-synthesized peptides from Quality Peptide USA.

Is BPC-157 research-grade?

Yes. Every batch of BPC-157 sold by Quality Peptide USA is released to a ≥ 99% HPLC purity specification, with mass-spec identity confirmation and LAL endotoxin testing on every lot. The certificate of analysis is published on the product page.

How should BPC-157 be reconstituted?

Reconstitute BPC-157 with bacteriostatic water (0.9% benzyl alcohol). Inject the water down the inside wall of the vial — do not inject directly onto the lyophilized cake. Swirl gently until fully dissolved. Refrigerate at 2–8°C after reconstitution.

What is the reported half-life?

≈ 4 hours (research models) Half-life figures from in-vitro models are not directly transferable to ex-vivo or in-vivo systems.

Where is BPC-157 synthesized?

BPC-157 is synthesized in the United States and ships from a US facility. No overseas drop-shipping, no customs delays, full domestic cold chain.

What testing is performed on each batch?

RP-HPLC purity (≥ 99% spec), ESI / MALDI-TOF mass spectrometry, Karl Fischer water content, LAL endotoxin screen, and bioburden. All results are published on the per-batch certificate of analysis.

Can BPC-157 be stacked with other peptides?

Many research protocols pair BPC-157 with complementary peptides — the Glow stack for dermal models, the Wolverine stack for tissue repair, or GHRH/GHRP secretagogue blends for somatotropic studies. Review the published literature for your specific endpoint before designing a stacked protocol.
