Weighted factor result: 7.9/10, rounded to 8/10 on our half-point scale.
Direct answer
Step One Ventures is the research-peptide storefront at s1research.net and earns 8/10. PeptidePrices reconciled 40 evidence identities from its complete retained archive. Thirty-three identities matched official Freedom Diagnostics, ILS Laboratories, or Kovera Labs records. The one additional public unavailable lookup is Reconstitution Solution report IF-824-QSA-TR006-BTL26561-02, not a BPC-157 or GLP-3R listing certificate. Ten of 23 active comparison rows have one eligible exact current certificate; 13 rows correctly remain empty.
Evidence summary
Step One's strongest legitimacy signal is its retained laboratory record: 33 of 40 evidence identities matched official issuer records, and the one additional public Freedom lookup is labeled unavailable rather than failed.
The evidence supports 8/10. The archive and exact issuer matches are strong; the 2025 start date, small independent review sample, and 13 deliberately empty current listing rows limit the broader record. Code peptideprices gives 10% off and was manually verified on September 8, 2026; the public banner separately advertises SAVE10.
PeptidePrices reconciled Step One's complete retained archive on September 3, 2026. The source contains 36 product observations and 88 discovered document URLs. Seventy-one confirmed files and 71 complete page renders support 40 checker identities. One archive observation had no certificate, while five GLP-3R and GLP-2T files became strength-specific identities. This is why the observation, identity, file, and page totals differ.
The public library contains 34 Step One records. Thirty-three identities matched official laboratory records: 26 Freedom Diagnostics, six ILS Laboratories, and one Kovera Labs. One additional Freedom lookup was unavailable and remains labeled as unknown. Six retained exception states are non-public: two Freedom no-matches, two records not yet verified, one unsupported BT Labs record, and one unresolved unsupported-laboratory record. The BPC-157 10 mg report for lot BP041726S1 lists LC-MS identity, 99.09% HPLC-UV purity, 11.94 mg measured content, and two endotoxin passes at a stated 0.05 EU/mL sensitivity.
Step One's current comparison catalog has 23 active rows across 14 compounds. Ten rows have one eligible exact current certificate. GLP-3R 10 mg, 20 mg, and 30 mg resolve to separate Freedom identities; GLP-3R 60 mg stays empty. Thirteen rows have no badge because the exact strength is absent, the issuer returned no match, the laboratory is unsupported, or several retained strengths remain grouped under one evidence identity. The store accepts cards, Zelle, and ACH. Its FAQ lists FedEx, UPS, and USPS, same-day processing before 2 PM Eastern, free shipping at $250, final sales after shipment, and a 48-hour claim window for damaged, incorrect, or missing items.
Step One is a US research supplier founded in 2025. 11 Peptide Critic reviews at 4.3/5 and a 3.7/5 Trustpilot profile with one five-star review form a limited independent record. The complete retained archive and 33 exact issuer matches support the 10/10 COA factor. The short operating history and thin review sample keep reputation at 4.5/10. With transparency at 7/10 and operations at 8/10, the weighted score is 7.9 and rounds to the owner-approved 8/10. Affiliate status has no score weight.
The October 3 external recheck found11 buyer posts at 4.3/5 on Peptide Critic and one five-star Trustpilot post; the Trustpilot TrustScore is3.7/5, not the star rating of that individual review. Readable community accounts describe repeat purchases, prompt shipment and pricing, while lower-rated posts report disappointing product experiences. Those subjective product accounts are not substituted for laboratory assays. Peptide Critic discloses affiliate earnings, and its small community sample is treated as service evidence rather than an independent chemical test.
Same-day processing is stated before 2pm Eastern.
FedEx, UPS, and USPS are listed; shipping is free at $250.
Sales are final after shipment, and order problems must be reported within 48 hours.
