Chemyo, an online supplier known mostly for SARMs and related research chemicals, has permanently closed. If you used to order from Chemyo, this page covers what’s known about the closure, what to do about an open order, and how to check a new supplier before you order.
All compounds discussed are sold for laboratory research use only and are not for human consumption.
The short version
- Chemyo announced a permanent closure on September 8, 2026.
- No reason for the closure was given.
- Chemyo said no other site may represent it or take payment for it.
- No successor or new domain has been named.
What we know about the Chemyo closure
Chemyo posted its permanent-closure notice on September 8, 2026. The notice did not give a reason.
The notice also warned that no other website is authorized to represent Chemyo or accept payment on its behalf. That warning matters: any site claiming to be the new Chemyo is not, by Chemyo’s own statement.
Chemyo is one of several research suppliers that closed in 2026. See our tracker of research vendor closures for the full list.
If you had an open Chemyo order or store credit
- Contact the company’s support directly, if a contact is still listed. It’s the only direct route to your order.
- Save your receipts, order emails and tracking numbers.
- If you paid by card and never received your order, ask your card issuer about a dispute before the time limit runs out.
- Download any lab reports you rely on while the company’s pages are still online.
What Rogue Compounds carries
Rogue Compounds focuses on research peptides, with a smaller line of research capsules, and doesn’t carry most of the SARMs Chemyo was known for. Here’s what overlaps, each with a batch COA on its product page:
| Compound | Research area |
|---|---|
| YK-11 | Research capsules; studied in myostatin and androgen-receptor research |
| SLU-PP-332 | Research capsules; studied in ERR agonist and metabolic research |
| 5-Amino-1MQ | Research capsules; studied in NNMT inhibition research |
| Methylene Blue | Research capsules; studied in mitochondrial research |
| Noopept | Research capsules; studied in nootropic research |
| BPC-157 | Peptide fragment studied in tissue research |
| TB-500 | Thymosin beta-4 fragment studied in tissue research |

How to choose a new research supplier
When a vendor you trusted closes, it’s tempting to pick the next cheapest listing. A better approach is to check every candidate against the same short list:
- A batch-specific Certificate of Analysis for the exact product and batch you would receive, not a generic or old report.
- Purity and identity on the same report. HPLC shows purity. Mass spectrometry confirms the compound is what the label says.
- A way to verify the report with the lab that issued it, such as a lab-hosted link or a QR code, so you are not relying on a PDF anyone could edit.
- A real, reachable business: working support email and phone, clear shipping and refund policies, and a U.S. shipping origin if speed matters to you.
- Buyer protection. Be cautious with any new vendor that only accepts payment methods you can’t dispute, like wire transfers or gift cards.
Our guide How to Read a Peptide COA explains each part of a lab report, and our peptide price report shows how pricing compares across vendors.
How Rogue Compounds compares on those checks
- Batch COAs: every product page shows the COA for the batch currently shipping, and every passing batch is public in our COA Library.
- Purity and identity: each batch is tested by an independent, ISO 17025 accredited U.S. laboratory for HPLC purity and mass spectrometry identity.
- Lab verification: each vial label carries a batch number and a QR code that opens that batch’s report on the testing lab’s own website.
- Shipping: U.S. only, by UPS 2-Day, with same-day dispatch on orders placed by 12 PM MT. P.O. Box orders ship USPS Priority Mail.
- Sourcing: small batches made only for Rogue, with new batches made in the USA. See where our peptides are made.
Rogue Compounds is not affiliated with Chemyo and has no access to its orders, customer accounts or records.
