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.

Every batch goes through a layered quality control process. We verify the identity and purity of the raw material, then test the finished solution to confirm the labeled concentration.

Methods: Vendor testing page states HPLC for purity/potency and FTIR for identity; product pages add Mass Spectrometry for identity; third-party review sites further cite IR, GC-MS and LC-MS. All vendor-stated. COAs are searchable by batch code on the public testing page. No NMR confirmed..

Finnrick — NOT in database
Chemyo has no vendor page in the Finnrick independent-peptide-testing database (https://www.finnrick.com/vendors/chemyo returns HTTP 404 as of 2026-06-27). Finnrick is peptide-focused and Chemyo is a SARMs/nootropics vendor, so the absence is partly expected, but it means no Finnrick independent purity data exists for this vendor.

S&N Labs (Glendale, CA) — named only by review sites, UNVERIFIED
Multiple third-party review articles state Chemyo uses 'S&N Labs' in Glendale, CA for independent HPLC/UPLC, LC-MS and GC-MS testing and that products are manufactured/induction-sealed/batch-coded in a US facility. Chemyo's own testing page does NOT name this lab. Treat the lab identity as unverified review-site attribution.

Trustpilot4.4(33)
Trustpilot4.4(33)

~4.4/5 over ~27-33 reviews (figures vary by snapshot); small sample, profile appears unclaimed. Snippet-only — live page 403'd to automated fetch.

Algorithmic 'Very Likely Safe' — credits 10-year domain age, valid SSL and money-back payment methods, while flagging that the site 'sells drugs for which prescriptions are required'. A lenient checker; not an endorsement.

Algorithmic 12.6/100 'high-risk' rating, recommends 'stay away' citing phishing/spam association factors. UNVERIFIED — snippet-only (page 403'd); conflicts sharply with ScamAdviser. Both are automated, not human reviews.

BBB profile 'Chemyo Labs' lists the SAME Wilmington, DE address as CHEMYO LLC (4023 Kennett Pike #59371); rating 'A+', NOT BBB accredited, file opened 2025-11-19. A customer review alleges the business 'sold MK677 product to minors 16 years of age with no age verification.'

3.0/5 from only 2 reviews — negligible sample.

Complaint-aggregator profile; lists support phone (302) 543-2011. Mixed individual reports.

Knoji4.1(22)

Consumer review aggregator (22 reviews, compared against 707 lab/scientific brands); page dated 'May '26' per its own title, appears currently maintained. Direct fetch 403'd (unverified, snippet-sourced per firewall rule 4). NOT yet in the existing build profile — genuinely new.

4.3/5 (7 reviews) as quoted by a secondary editorial source (cofes.com); no first-party Google Maps/Business Profile URL could be resolved directly, so cited via the secondary source that reports the figure. UNVERIFIED, small sample (n=7). NOT yet in the existing build profile.

Trustpilot snippet reports ~4.4/5 across roughly 27-33 reviews on the chemyo.com profile (small sample; profile appears unclaimed/unverified, and the live page returned HTTP 403 to automated fetch so the score is snippet-only). Reputation is sharply split by channel: SARMs/peptide review sites (many of which run an affiliate coupon 'INSIDE10') are strongly positive on purity and shipping, while bodybuilding forums (iSARMS, Ironoverload, Evolutionary, EliteFitness) host 'Beware of Chemyo' threads alleging bait-and-switch and product spiking. Forum sentiment on those boards skews negative but those communities are known to disparage non-sponsor sources.

FAQ

CitedV31
Is Chemyo legit, and what is on record?
Chemyo (chemyo.com) is a US-facing research-chemical retailer operating as CHEMYO LLC (Delaware, est. 2016) and selling primarily SARMs and nootropic liquids/powders. On record: a strong but small Trustpilot sample (~4.4/5, ~30 reviews), an algorithmic 'Very Likely Safe' from ScamAdviser versus a 'high-risk' rating from Scam Detector, a BBB 'Chemyo Labs' profile (A+, not accredited, opened Nov 2025) with a review alleging a sale to a minor, no FDA warning letter found as of 2026-06-27, and bodybuilding-forum threads alleging product spiking and bait-and-switch (from communities known to disparage non-sponsors). PeptideCompass computes no vendor score — weigh the cited facts yourself. Research use only.
trustpilot.com
Does Chemyo sell peptides?
Largely no. Chemyo's live catalog is SARMs and nootropic research compounds sold as 50 ml liquids and powders; it does not list injectable research peptides such as BPC-157, TB-500 or GLP-1 agonists. Several third-party review sites describe Chemyo as a 'SARMs & peptides' source or claim it stocks BPC-157/TB-500 — this conflicts with the live storefront and may reflect outdated content, SEO, or confusion with clone domains. Research use only.
chemyo.com
Does Chemyo provide COAs / lab tests?
Yes — Chemyo publishes a public lab-results page and says every batch is third-party tested for identity (FTIR/MS), purity and concentration (HPLC), with COAs searchable by batch code and a certificate tied to each order (claimed >99% purity). The lab is not named on-site (review sites attribute it to 'S&N Labs', Glendale CA — unverified), and Chemyo is not present in the Finnrick independent-test database, so the purity record rests on vendor-published COAs rather than independent assays. Research use only.
chemyo.com
What payment methods does Chemyo accept, and how does it ship?
Credit/debit cards, cryptocurrency (BTC, 10% discount) and a US-only domestic E-check via Checkbook.io (5% discount). Orders process/ship in 24-48 hours; US delivery is typically 2-5 business days and international 7-21 business days, with free shipping over $100 (US) / $275 (international). Chemyo advertises a delivery guarantee with reship/refund for lost, seized or damaged packages. Research use only.
chemyo.com
Are Chemyo's products legal or intended for human use?
Chemyo states everything it sells is 'strictly intended for laboratory research' and not for human consumption. SARMs are not FDA-approved for human use and are sold as research chemicals; buyers are responsible for local import compliance. Research use only.
