Crush Research
Two-Lab Verified, Owner-Disclosed Q&A
Verdict
Best-documented testing program on the list, now corroborated by an owner-disclosed Q&A. Two named third-party labs (ILS Laboratories, San Diego; BT Labs) with QR-verifiable COAs, a full contaminant trifecta (endotoxin USP <85>, heavy metals ICP-MS USP <233> 5-metal panel, sterility PCR) on current batches, 3-vial conformity reporting, and a large public COA archive spanning ~6 months. Owner Rory ("PepTok") operates openly as a multi-source reseller of China-manufactured peptides with no USA-made claims. The caveats: a sub-1-year track record (launched October 2025), an acknowledged critical independent ("Krause") result, historical fill variance, a deliberately tiny bulk-only catalog, and chronic out-of-stock.
Documented strengths
- Two named 3P labs: ILS Laboratories (San Diego, QR-verifiable) and BT Labs (USP-based analytical panel)
- Full contaminant trifecta on current ILS batches: endotoxin (USP <85>), heavy metals (ICP-MS USP <233>, 5-metal As/Cd/Cr/Hg/Pb), sterility (PCR)
- Only vendor with Chromium in heavy metals panel (5 metals vs Peptide Partners 4)
- Large public COA archive (48-59 COAs) spanning 6+ months of continuous batch testing
- Conformity testing: 3 vials per batch with mean purity and std dev reported
- Multiple vials tested per batch (not one-and-done)
- Owner publicly identified (Rory, "PepTok"); operates openly as a multi-source reseller of China-manufactured peptides with no USA-made claims
- Strongest per-mg value in the peer set on the benchmarked compounds, including the best bulk pricing tested
- Vials labeled with concentration, manufacture date, batch #
- Card processing now accepted alongside Zelle, crypto, and bank transfer; active owner communication; 50% discount guarantee on independent test failures
Considerations
- Very young: launched October 2025, well under one year operational
- Tiny, bulk-only catalog (~10 peptides; 3-, 5-, and 10-packs only, no single vials)
- Chronic out-of-stock is the dominant customer complaint; owner acknowledges it and declines to fix via higher prices
- Sterility and heavy-metals testing apply to newer batches forward; older batches were endotoxin + HPLC only
- No published Finnrick result yet, though Finnrick now lists Crush with tests in the pipeline (1 logged, 4 unlisted, 0 published); the owner also acknowledges a critical independent ("Krause") result
- Self-reported fill variance on earlier batches (TB-500 +30%, Ipamorelin -20%); a visually contaminated batch was caught and trashed
- Zelle, crypto, and bank transfer (5% off) carry no chargeback protection
- US-only shipping: international shipping was discontinued in early June 2026 (effective immediately) to comply with international shipping/customs regulations, not a service-quality change; non-US buyers are no longer served

Summary
Still the strongest documented testing program in the peer set, and the owner-disclosed Q&A backs it up rather than walking it back. The honest gaps are tenure (under a year), an acknowledged critical independent result, and a tiny bulk-only catalog that is frequently out of stock, which makes Crush a high-confidence supplemental source rather than a one-stop shop. Verify the specific batch against the COA archive before ordering.
