Pure Rawz
Established vendor with an open, tiered affiliate (7% to 15%) and MZ Biolabs HPLC/MS COAs. Independent retests showed purity below label (e.g. ~91% BPC-157 vs 99% advertised), many COAs predate 2023, and EU->US shipping runs 6-14 days.
Score breakdown
Strengths
- Open affiliate: 7% base rising to 15% for active promoters
- MZ Biolabs HPLC/MS COAs published
- Reasonable pricing
Weaknesses
- Independent retests below label (e.g. ~91% BPC-157 vs 99% advertised)
- Many COAs predate 2023; batch-traceability gaps
- Slow shipping (6-14 days) and slow support
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
Pure Rawz: 0.40×6 + 0.30×6 + 0.15×5 + 0.15×7 = 6.0
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.
Reviews
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.
