Trust Index breakdown

DerivedV3

The Trust Index weighs five evidence pillars — purity claims-vs-reality, testing transparency, enforcement conduct, operational accountability and reputation integrity — into a single 0–100 factor. Nothing here can be bought.

Thinly Documented. Cited facts on file, but no allowlisted independent assay yet — a precise index is withheld. A precise number is withheld rather than guessed — absence of evidence is never shown as a low score.

Methodology & independence

CitedV4
  • The Trust Index is computed only from cited facts — and can never be bought.
  • Sponsorship & affiliate are excluded by construction — they never move the score, sort, or inclusion.
  • Facts are dated and cited; absent data lowers confidence, never the score (absence isn’t evidence of bad).

No affiliate relationship with this vendor.

Independent tests tracked
1 on file
GMP / ISO claim
not on record
Koi states every lot is tested in-house and re-run by an 'independent ISO/IEC 17025-accredited' laboratory, with a per-batch COA published on each product page and in a public, searchable COA library (lot format 'KOI-YYYY-MMDD-x'). Methods claimed: reverse-phase HPLC-UV for purity (>=99% release criterion), LC-MS for identity, ICP-MS heavy metals, and LAL/USP <85> endotoxin. CAVEAT: the COA library page does NOT name the lab, but the BPC-157 product page names 'Freedom Diagnostics Testing' (Franklin, TN) as the ISO/IEC 17025 lab; Freedom Diagnostics' own ISO/IEC 17025 accreditation could not be independently verified online. No independent community testing (Finnrick / Janoshik / vialaudit) for Koi was found as of June 2026 - the only published COAs are vendor-commissioned.

Methods: HPLC-UV (purity), LC-MS (identity), ICP-MS (heavy metals), LAL / USP <85> (endotoxin), counterion/TFA content (vendor-stated); re-run by an unnamed 'independent ISO/IEC 17025' lab. BPC-157 COA attributes testing to Freedom Diagnostics Testing.. Labs: Freedom Diagnostics Testing (named only on the BPC-157 product page; the COA library page leaves the lab unnamed; its ISO/IEC 17025 accreditation is not publicly verifiable).

PR wires + affiliate listicles (synthesis)Mixed2026-06
Koi's externally visible reputation is overwhelmingly promotional and freshly minted: a cluster of June 2026 paid press-release wires (GlobeNewswire, EIN Presswire, syndicated to Yahoo Finance, Manila Times, WBOC) announcing product 'launches', plus same-window 'best peptide vendor' / dedicated-review posts on content sites (learnmuscles.com, pspeptides.com, radiologykey.com, onpattison.com). These echo the vendor's own copy (>=99% HPLC, ISO 17025, same-day US shipping) rather than independently test it. No organic Reddit (r/Peptides) or bodybuilding-forum discussion of Koi was located - consistent with a vendor only ~2 months into public operation.

Favorable 'review' published 2026-06-10, the same day as Koi's wholesale press release; reads as content marketing rather than independent editorial

Listed in a 'Trusted US Peptide Vendors' roundup - affiliate-style listicle, not independent testing

Algorithmic trust score 0/100, label 'Likely Unsafe' — flags WHOIS-privacy-shielded ownership, low site traffic, a domain registered only ~2 months prior, and sale of prescription-requiring products; a lenient/strict checker like this is never itself proof of fraud, only a heuristic signal, and contrasts sharply with the vendor's PR-seeded Trustpilot figures already on file.

0 reviews on record; 301-redirects to smartcustomer.com/reviews/koipeptides.com, which also confirms 0 reviews and prompts 'Be the first to write a review.'

Trustpilot snippet shows koipeptides.com 'Great' 4.2/5 across only 21 reviews; the direct Trustpilot page returned HTTP 403 so the figure is snippet-sourced and unverified. The profile is very young (the .com domain was only created 2026-04-21) and the broader review footprint is dominated by paid press-release wires and affiliate-style 'best peptide vendor' listicles published in the same June 2026 window - i.e. a PR-seeded reputation rather than an organic forum/Reddit track record (no Reddit or bodybuilding-forum threads on Koi were located).

FAQ

CitedV31
Is Koi Peptides legit, and what is on record?
Koi Peptides (koipeptides.com, operated by Koi Research Labs LLC) is a US-facing research-peptide storefront that launched online around May 2026 - its .com domain was registered 2026-04-21. It publishes per-batch HPLC/LC-MS COAs in a searchable lot library and carries a small, favorable Trustpilot footprint (4.2/5 across 21 reviews, unverified). On record as caution points: the brand claims a 2022 founding and '2,400+ researchers' that its ~2-month-old web footprint cannot corroborate; its registered address is a known Wyoming mass-registration agent (Registered Agents Inc.) rather than a verified warehouse; and the ISO/IEC 17025 lab it cites (Freedom Diagnostics Testing) has no publicly verifiable accreditation. PeptideCompass computes no vendor score - weigh the cited facts yourself. Research use only.
who.is
Where does Koi Peptides ship, and how fast?
Koi ships domestically via USPS Priority Mail and UPS, quoting 2-4 business days standard (expedited 2-day and overnight available), with same-day dispatch on orders before the daily cutoff. Standard US shipping is $9.95 and free over $200. International shipping is offered only to 'qualifying research institutions' in Canada, the UK, EU, Australia and select APAC countries, requiring institutional addresses, end-use declarations and pre-approval. Research use only.
koipeptides.com
What payment methods does Koi Peptides accept?
Koi's FAQ lists major credit cards, ACH, and wire transfer; it does not advertise cryptocurrency (one third-party snippet mentioned crypto, which the site's own FAQ does not corroborate). Accepting standard cards is unusual for research-chemical sellers and, if accurate, would preserve card-chargeback recourse. Research use only.
koipeptides.com
Does Koi Peptides provide COAs or lab tests?
Yes - Koi publishes a per-batch Certificate of Analysis on each product page and in a public, lot-searchable COA library, claiming reverse-phase HPLC for purity, LC-MS for identity, plus heavy-metal and endotoxin screens, all re-run at an 'independent ISO/IEC 17025' lab. The BPC-157 COA names Freedom Diagnostics Testing (Franklin, TN); however, the COA library page itself leaves the lab unnamed, and Freedom Diagnostics' ISO/IEC 17025 accreditation is not publicly verifiable. No independent community testing (Finnrick, Janoshik, vialaudit) of Koi was found. Research use only.
koipeptides.com
What is the return and refund policy?
Koi does not accept returns of opened vials 'for unrelated reasons,' which it frames as standard for research chemicals. If a peptide fails to match its COA on an independent retest, Koi states it will replace the item or refund the order. Damaged or incorrect shipments must be reported within 48 hours of delivery with photos; lost packages are reshipped free once the carrier confirms loss. Research use only.
