Vendor Standard
What I found digging into 17 research-peptide vendors: who actually names their lab and posts real batch COAs, and who just says "third-party tested" and hopes you don't ask. This rates the paper trail, not the people.
How to read this
The Peptide Standard Score measures how transparent a brand is, not how effective its products are. Scores are based on publicly available evidence, including testing, documentation, batch traceability, supplier consistency, and community reputation. Updated regularly as new information becomes available.
OROS Research
reptides S · 7.5Tests every lot at a named ISO 17025 lab, keeps a proper batch COA library, BBB accredited. About as buttoned-up as this list gets.
Elite Research USA
reptides A · 7Batch COAs from a named lab (BioRegen) with an actual LC-MS chromatogram and a conforms table. reptides has them A-tier.
Oath Research
Batch-plus-accession COAs from named labs (ILS, Freedom Diagnostics), HPLC/MS/endotoxin, and a per-volume test history. Genuinely strong once you're in.
Forge Performance
Two named labs (ILS, Freedom Diagnostics), MS for identity and HPLC for purity, and COAs keyed to the vial cap color. Newer, but they get it.
Polaris Peptides
Dated batch COAs from named labs (AccuMark, Janoshik), HPLC-MS, with both latest and previous results. And they'll straight up tell you a 5mg vial tested at 7.5mg.
Blank Peptides
reptides B · 5.8Independent lab (Freedom Diagnostics), HPLC and mass spec, dated batch COAs with lot/date/method, and separate endotoxin reports. Their COA page is better than their homepage lets on.
Orbitrex Peptides
QR-codes every vial to its COA, and independent Finnrick testing rates it A (100% identity across 26 samples). Veteran-owned, Texas-based. They still don't name their own labs.
Peptide Partners
reptides S · 7.8Batch-specific downloadable COAs, named labs, endotoxin and sterility. reptides ranks them #1. The only soft spot is thin independent reviews.
Pure Peptides
reptides A · 7.3Names MZ Biolabs and posts a real COA/MS/endotoxin layer. Trustpilot is mixed though, with some people saying they didn't get refunded for failed peptides.
Crush Research
reptides A · 7Says every batch gets its own COA (not a generic one) and verifies purity by independent HPLC. Veteran-owned, fast shipping. They just don't name the lab.
Evolve Peptides
Claims a wide testing net (purity, sterility, endotoxin, heavy metals), shows per-product COA images, and dangles a 200% money-back guarantee. Labs aren't named, though.
Simple Peptide
Has a real COA lookup by product, lot, or accession number, which is good traceability, but you need an actual lot to see the certificate. US-based (Delray Beach).
Peak Peptide
COAs with an actual HPLC chromatogram, MS data and a heavy-metals panel, which is more than most. But they won't say if it's an independent lab or in-house, and all sales are final.
Kimera Chems
reptides A · 7Established multi-category shop that says every batch is tested with COAs for everything, but names no lab or method. reptides has them A-tier.
Peptide Supply Co
Says every batch is independently tested with viewable COAs and ships free 2-day. Labs and methods aren't named.
Rescue Research USA
Claims per-batch independent testing with a COA page, but it only takes Zelle, Venmo and CashApp, which leaves you no chargeback if something goes wrong. Labs aren't named.
Lumira
Peptaura's old top seller (reportedly ex-Welon). Evidence points to a product sold as retatrutide not testing as retatrutide back in May 2026. They refunded fast through Peptaura and are now showing unavailable.
Aggregators & Marketplaces
Platforms that list other people's product instead of making their own. I score these on marketplace terms, so don't read their number against the vendor scores above. Different job, different rubric.
Peptaura
AggregatorOpen marketplace bundling about 10 vetted sellers (60+ compounds, 252 COAs). Shows per-seller reviews and COA counts and has real buyer protection. The catch: the COAs come from the sellers, not from Peptaura.
