BPC-157 — FAQ
How do I verify BPC-157 purity?
Look for a hosted, batch-specific Certificate of Analysis (COA) from a named third-party lab (e.g. Janoshik, MZ Biolabs, or a Finnrick-verified result) showing HPLC purity for the exact lot you receive. Self-reported '99%+' with no PDF is a claim, not evidence.
What is a fair price per mg for BPC-157?
Among audited vendors, purity-adjusted price-per-mg ranges roughly $4–6/mg at 10mg vial size. Headline prices below that often depend on large coupon codes — we adjust for that in the Value axis.
How we rank
One formula, the same for every vendor including our partner. Argue with the weights — that's the point.
Overall = 0.40 × Transparency + 0.30 × Purity + 0.15 × Shipping + 0.15 × Value
How each axis is scored
Transparency (×0.4). COA depth, named third-party labs, breadth of test types (HPLC base; +MS, +LAL, +heavy metals, +sterility), public batch traceability. Claim-only purity (no hosted PDF) caps this axis.
Purity (×0.3). Median/recent batch purity from hosted COAs + independent lab confirmation (Finnrick/Janoshik). Self-reported '99%+' with no batch PDFs scores low.
Shipping (×0.15). US-domestic speed/reliability and stock consistency from real shipping data; international-only or undisclosed scores lower.
Value (×0.15). Purity-adjusted price per mg vs the cross-vendor median for the same peptide/vial; discount-dependency penalized.
Why trust this comparison
- Every vendor is scored from real evidence on four public, weighted axes — before we know any margins.
- Purity claims are cross-checked against named third-party labs (MZ Biolabs, Finnrick, Janoshik). Claim-only purity is marked as such.
- The scoring code can't read which vendor pays us — the editorial-commerce firewall is enforced in software.
- We disclose the 20% / 10% Alpha Pro commission on every page, above the first link.
Vendors out-rank our own partner: Peptide Partners (9.0) and Protide Health (8.9) and Ascension Peptides (8.8) both score above Alpha Pro (8.6). We left it that way.
