A closure notice and nothing behind it
Chemyo was a research chemical and peptide seller that, for a period, appeared on a good many recommendation lists. It no longer trades. When we opened chemyo.com on October 19, 2026, the homepage and the about page displayed a single statement: Chemyo LLC permanently closed on September 8, 2026. The notice says the company no longer accepts payments anywhere, that orders placed before September 8 will be fulfilled, and that support remains available for customers with past orders. It also warns, in plain terms, that any other website claiming to be Chemyo is an impersonator, and it offers a tool for reporting such sites.
We tried to build the usual picture of what the company had published while it was open, and we could not. Archive access was unavailable during our check. Finnrick, the independent testing aggregator we consult for every supplier, has no vendor page for Chemyo. The company’s Trustpilot page returned HTTP 451, the status code for content withheld for legal reasons. We found no FDA warning letter naming the company. The result is a record in which third-party testing, laboratory names, certificate availability, analytical methods, catalog, formats, prices, shipping terms and payment methods are all unknown, not because the company hid them but because there is no longer anywhere to read them.
The one testing statement that survives
The single substantive fact about Chemyo’s products that we can still cite comes from the company’s own terms and conditions, which remained reachable. Those terms stated that products were not sterilized or tested by Chemyo LLC for safety or efficacy. Read carefully, that is a statement about what the company itself did not do, and it does not tell us whether any outside laboratory tested the material. We record it because it is the only documentary evidence we have, and because a reader who remembers Chemyo as a tested source should know that the company’s own terms did not claim in-house testing.
Chemyo LLC is the entity named in the closure notice. The company’s headquarters country and location are not stated on the surviving pages and are recorded as unknown.
What readers of older lists should know
Anyone who finds Chemyo on a recommendation page written before September 2026 should treat the entry as void. The company closed itself; it was not, on the evidence we have, shut down by a regulator, and the notice describes an orderly wind-down with pre-closure orders fulfilled and past-order support maintained. That is a cleaner ending than some suppliers on this site have had. It is still an ending.
The practical risk now is impersonation. The closure notice goes out of its way to say that any site trading under the Chemyo name is not Chemyo, and a brand with a long list of past customers is exactly the kind of name a copycat would borrow. A reader who encounters a Chemyo storefront accepting payment should assume it is unrelated to the closed company, should not rely on any certificate or history attributed to the original, and can report the site through the tool on chemyo.com. There is no supplier here to recommend or to warn against, only a name that should no longer appear on a shopping list.
What we liked
What we would want fixed
- The company permanently closed on September 8, 2026 according to the notice on its own homepage and about page, and no longer accepts payments anywhere.
- No historical catalog, testing, location or pricing data could be verified, because the site now shows only the closure notice and archive access was unavailable.
- Chemyo's terms stated that its products were not sterilized or tested by Chemyo LLC for safety or efficacy.

Frequently asked questions
Is Chemyo still open?
No. As of our check on October 19, 2026, the chemyo.com homepage and about page show only a closure notice stating that Chemyo LLC permanently closed on September 8, 2026 and no longer accepts payments anywhere. Orders placed before that date are being fulfilled and support remains available for past orders.
Did Chemyo publish COAs?
We could not verify. The site now shows nothing but the closure notice, archive access was unavailable during our check, and Finnrick has no vendor page for Chemyo. The one testing statement we can cite is from its terms, which said that products were not sterilized or tested by Chemyo LLC for safety or efficacy.
What if I find a site claiming to be Chemyo?
Chemyo's own closure notice says that any other website claiming to be Chemyo is an impersonator, and it includes a tool for reporting such sites. A storefront currently selling under the name is not the company that closed, and nothing in our record vouches for it.
