ERP
This is one entry from the TitrateLab Vendor Graveyard, a dated, primary-source archive of peptide-market shutdowns, exit scams, and enforcement actions. Documented as community group-test findings, 2025. Sources for this entry are named inline below and numbered in full on the parent archive page.
A community-organized group test of approximately 80–85 participants submitted ERP-branded product to Janoshik under a neutral label (“Strong Like Bull”) specifically to prevent ERP from co-opting the resulting COAs for marketing. The test produced two separable quality findings:
| Test | Label | Measured | Delta |
|---|---|---|---|
| SS-31 mass | 50 mg | 44.10 mg | −11.8% |
| SS-31 endotoxin | — | ~26.79 EU/vial | above validated reporting range |
Underfilling at the 11.8% level is not within any reasonable measurement-error band; it is a mass-accuracy miss that a prospective buyer needs to factor into dosing. The endotoxin reading sat above the assay’s validated reporting range, which is itself an actionable signal for injectable product.
The customer-service response is as consequential as the technical findings. ERP’s documented reactions to buyers presenting the group-test COAs included: shifting explanations (overfill, dissolution issues, “that’s not our label”), retroactive policy changes (“that fee wasn’t on the invoice when I bought”), escalation to chargeback threats, and in several documented cases banning customers from their Telegram channel and deleting the chat history of the dispute.
Why it belongs in the archive: most vendor-quality issues resolve at the level of “one bad batch, vendor makes it right.” The documented ERP pattern reads differently to us. Based on the Krysia Substack investigation and the corroborating GLP-1 Forum thread, the combination of a mass-accuracy miss, an endotoxin signal, and the response pattern looks less like individual-batch remediation and more like systemic deflection. A prospective buyer should evaluate ERP knowing both the technical finding and the customer-service response style.
