Passing 6 of 6 checks clear
Research-use-only framing Pass
Listings clearly state products are for laboratory research use only.
No health or dosing claims Pass
No therapeutic, dosing, or human-use claims anywhere in the listing.
Lab documentation available Pass
Batch-tied COAs (HPLC purity + mass-spec identity) exist and are accessible.
Transparent pricing Pass
Vial sizes and prices are listed clearly and consistently, no bait pricing.
Shipping & reship policy Pass
A stated shipping, tracking, and reship/refund policy is published.
No open Scam Watch flags Pass
No unresolved counterfeit, non-delivery, or COA-forgery reports on file. 2026-08-29: CLEAN ON EVERY CHECK, AND YESTERDAY'S READ GAP IS CLOSED. /returns-refunds-policy/ returned a full body today (empty yesterday), so the guarantee is now VERIFIED FIRST-HAND RATHER THAN CARRIED: 'We stand behind all our products with an industry-exclusive 60-day money-back guarantee'; 'Standard returns are accepted within 14 business days of delivery for unused and unopened items'; 'All returns must be pre-approved - do not ship any return before an RMA has been issued.' Note this is OUR read gap closing, NOT a vendor remediation. Self-limiting RUO language verbatim intact: 'We do not describe effects, outcomes, doses or protocols, because a research-use-only supplier making those statements is operating outside the boundary for the category.' Per-vial pricing with size on every card, unchanged: BPC-157 $52.99 for 5/10/20MG; GLP-3 (R) $125.99; KLOW Blend $299.99. COA index header 'Batch-specific Certificates of Analysis for 53 research compounds' - 53 entries counted on the page, HEADER MATCHES LISTING. no_scam_flags MOVES PENDING -> PASS: the name-adjacency disclaimer appears TWICE on the homepage, verbatim 'We are not affiliated with peptideswarehouse.com or any similarly named websites, brands, or suppliers', and THE NON-DELIVERY REPORTS IN SEARCH BELONG TO THAT DIFFERENT DOMAIN - attributing them here would be a fabricated flag, which is its own compliance failure. No dated adverse report naming peptide-warehouse.com was found. THE JS COUNTERS AGAIN RENDERED '0%+ Verified Purity / 0% Batches COA-Tested / 0 Independent Assays' IN A SERVER-SIDE FETCH - THIS IS A RENDERING ARTIFACT, NOT A VENDOR CLAIM OF ZERO, and must not be scored. || PRIOR: 2026-08-28: CLEAN READ AGAIN, and I am again EXPLICITLY DECLINING to score the complaints that surface in search. The self-limiting RUO language is verbatim intact and is the best in the directory: 'We do not describe effects, outcomes, doses or protocols, because a research-use-only supplier making those statements is operating outside the boundary for the category.' Per-vial pricing with size on every card: BPC-157 $52.99 (5/10/20MG), GLP-3 (R) $125.99 (5-60MG), KLOW Blend $299.99. COA index header reads 'Batch-specific Certificates of Analysis for 53 research compounds' with HPLC and mass-spec method pages linked. THE 60-DAY MONEY-BACK GUARANTEE COULD NOT BE RE-VERIFIED TODAY - /returns-refunds-policy/ returned HTTP OK with an EMPTY BODY - so reship_policy is CARRIED AT PASS, NOT DOWNGRADED; a fetch failure is never evidence against a vendor. ATTRIBUTION GUARD APPLIED, and it is load-bearing: the on-page disclaimer appears TWICE - 'We are not affiliated with peptideswarehouse.com or any similarly named websites, brands, or suppliers' - and the non-delivery reports circulating in search belong to THAT DIFFERENT DOMAIN. Attributing them here would be a fabricated flag. Note also: the JS stat counters render as '0%+ Verified Purity / 0% Batches COA-Tested / 0 Independent Assays' in a server-side fetch - a RENDERING ARTIFACT, not a vendor claim of zero. || PRIOR: 2026-08-27: UPGRADED monitoring -> PASSING on a fully clean first-hand read of /, /coa-index/ and /returns-refunds-policy/. Five of six at pass; no_scam_flags stays PENDING only because of the attribution question below, not because of anything found against this vendor. THE SELF-LIMITING RUO LANGUAGE REMAINS THE BEST IN THE DIRECTORY, verbatim: 'We do not describe effects, outcomes, doses or protocols, because a research-use-only supplier making those statements is operating outside the boundary for the category', alongside 'Structure is verifiable by mass spectrometry. Outcome is not verifiable by anything on a Certificate of Analysis.' The site volunteers anti-overclaim education rather than marketing around it. Per-vial pricing is public with size on every card (BPC-157 $52.99/5MG, GLP-3 (R) $125.99 across 5-60MG, KLOW Blend $299.99). THE 60-DAY GUARANTEE IS CONFIRMED VERBATIM on the returns page - 'an industry-exclusive 60-day money-back guarantee' - with its limits stated openly (RMA required, maximum two opened products, customer pays return shipping, a 14-business-day standard window running in parallel). Disclosed limits on a generous policy is the correct shape. /coa-index/ reads 'Batch-specific Certificates of Analysis for 53 research compounds', HPLC + mass spec, searchable by compound and covering past batches; coa_documentation HELD AT PASS - the individual document viewer is JS-gated and per standing rule a fetch limitation is never counted against a vendor. I AM AGAIN EXPLICITLY DECLINING TO SCORE THE COMPLAINTS THAT SURFACE IN SEARCH: the non-delivery reports trace to peptideswarehouse.com (with an s), a DIFFERENT domain, and the vendor's own on-page disclaimer reads 'We are not affiliated with peptideswarehouse.com or any similarly named websites, brands, or suppliers.' Attributing them here would be a fabricated flag. RENDERING ARTIFACT, recorded so it is not misread next run: JS stat counters render as '0%+ Verified Purity / 0% Batches COA-Tested / 0 Independent Assays' in a server-side fetch - that is the fetch, NOT a vendor claim of zero. || PRIOR: 2026-08-26: CLEAN AGAIN ON FIRST-HAND READ; prior state confirmed. RUO framing remains the most disciplined and self-limiting in the directory, verbatim: 'Research-use-only is a boundary, not a disclaimer... We do not describe effects, outcomes, doses or protocols, because a research-use-only supplier making those statements is operating outside the boundary for the category.' The site also volunteers anti-overclaim education that cuts against its own marketing incentive: 'A stated purity is an area percentage... It is not a mass percentage of what is in the vial.' Pricing per-vial with sizes shown (BPC-157 $52.99/5MG, GLP-3 (R) $125.99/5MG, Gonadorelin $24.99/2MG, KLOW Blend $299.99). Returns policy detailed and unusually generous: 'industry-exclusive 60-day money-back guarantee', RMA required, refunds 'typically within 2-3 business days', 48-hour damage-report window, customer pays return shipping. Brand Clarification intact and now surfaced in two places: 'We are not affiliated with peptideswarehouse.com or any similarly named websites, brands, or suppliers.' coa_documentation HELD AT PASS, not downgraded: /coa-index/ claims and lists 'Batch-specific Certificates of Analysis for 53 research compounds' but each entry renders as an inert 'View COA - [compound]' label with no resolvable document URL in the fetched markup, so no certificate could be opened to confirm the batch tie, HPLC or MS content. That reads as a JS-gated viewer, i.e. a FETCH LIMITATION, and per standing rule a fetch limitation is never counted against a vendor. Recommend a browser read to convert this from carried to verified. I AM EXPLICITLY DECLINING TO SCORE THE COMPLAINTS THAT SURFACED IN SEARCH: aggregated non-delivery reports ('tracking numbers... never update', 'creating FedEx labels but never shipping them') trace to eroids.com/reviews/peptideswarehouse.com - the DIFFERENT, FORMALLY DISCLAIMED domain - and to peptides355.wiki, an SEO-spam page. Attributing them to peptide-warehouse.com would be a fabricated flag, and this is precisely the brand-confusion scenario the vendor's own Brand Clarification page exists to address. no_scam_flags stays PENDING solely because trustpilot.com/review/peptide-warehouse.com returned an empty body again, leaving the vendor's own '5-Star Rated on Trustpilot' footer claim UNVERIFIED in BOTH directions - absence of a read, not presence of a problem. || PRIOR: 2026-08-25: THE NAME-COLLISION ITEM RESOLVES IN THE VENDOR'S FAVOUR, AND THE VENDOR RESOLVED IT ITSELF. Read first-hand behind a 21+ age gate, the site now carries a dedicated FAQ and a 'Brand Identity & Research Scope' section stating verbatim 'We are not affiliated with peptideswarehouse.com or any similarly named websites, brands, or entities', with a linked Brand Clarification page. THE ADVERSE eroids AND TRUSTPILOT MATERIAL SURFACING IN SEARCH ATTACHES TO peptideswarehouse.com - A DIFFERENT, UNAFFILIATED SITE - and must never be carried against peptide-warehouse.com. Recorded permanently. THE CONTENT CHECKS ARE NOT MERELY CLEAN, THEY ARE EXEMPLARY, and the vendor states the standard better than our own checklist does, verbatim: 'We do not describe effects, outcomes, doses or protocols, because a research-use-only supplier making those statements is operating outside the boundary for the category.' Searchable batch COA index at /coa-index/ with HPLC + MS + endotoxin + heavy-metal panels and per-size batches - full coverage of what coa_documentation asks for. Pricing per-vial with size tiers (BPC-157 $52.99/5mg; GLP-3 (R) $125.99). Shipping Policy and 'Refunds & Order Issues' both linked in footer. no_scam_flags IS HELD AT PENDING PURELY FOR LACK OF A FIRST-HAND READ, NOT FOR ADVERSE EVIDENCE, and that distinction matters: the direct fetch of the Trustpilot page returned an EMPTY BODY (bot-blocked). Search summaries of that same page describe recent August 2026 reviews as POSITIVE - a ~$700 order shipped on time, one wrong item promptly re-shipped - which is also UNVERIFIED and therefore also moves nothing, in either direction. The Aug 4 review that moved this check to pending on 2026-08-24 has still never been read first-hand. If it cannot be read within the next few runs, recommend an operator eyeball rather than leaving a pending state that implies unresolved suspicion where none has been substantiated. || PRIOR: 2026-08-24: Five content checks verified clean first-hand: strong structural RUO framing ('boundary, not a disclaimer' section refusing effects/dosing claims), searchable batch COA index at /coa-index/, all prices displayed, Shipping + Returns/Refunds linked, 21+ age gate. no_scam_flags PASS -> PENDING (minor): search surfaced a NEW Trustpilot review dated Aug 4 2026 ('Useless support and product', Randy Hoopes) plus a GridInsoft 49/100 score; several complaint results conflate the UNAFFILIATED peptideswarehouse.com (site itself carries a brand-clarification disclaimer). Operator should eyeball the Trustpilot page before restoring pass. || PRIOR: 2026-08-23: CLEAN DAY — all six hold on first-hand homepage read: RUO framing structural ('Research-use-only is a boundary, not a disclaimer... We do not describe effects, outcomes, doses or protocols'), explicit prices on every SKU, /coa-index/ (53 compounds, read first-hand 08-22) still publicly linked, shipping + returns policies in footer. One OLD Trustpilot complaint (~March 2026, 'took money, didn't ship', resolved by chargeback) surfaced in search — single, old, resolved, not a pattern; moves nothing. Fetch failures noted without downgrade: /faqs/ and the Trustpilot page returned empty bodies. || PRIOR: 2026-08-22: /coa-index/ RENDERED FIRST-HAND FOR THE FIRST TIME — the page that returned empty bodies on 2026-08-20 and 2026-08-21 was read in full today (modified 2026-08-01). CONFIRMED: a public, ungated, alphabet-filtered library of 53 COMPOUNDS, each e [...earlier history truncated - see compliance-reports/ for the full record...]

Frequently asked

Is Peptide Warehouse verified?
Not yet — the vendor has not completed independent batch testing against its COA, which is not an accusation. Verification is never for sale.
What is the rating based on?
Nothing yet — ratings appear only from real, moderated reviews. They are never invented or influenced by payment.
