YK-11 is a synthetic steroid derivative, first described by researchers at Toho University in Japan, that acts as a partial agonist of the androgen receptor and raised follistatin expression in cultured mouse muscle cells. It is sold as a SARM, but structurally it is a steroid, and its entire evidence base is three cell-culture papers: there are no human trials and no animal efficacy trials. It has never been approved as a medicine anywhere, the FDA has warned consumers about SARM products, and WADA prohibits SARMs in sport at all times. Read the full YK-11 guide, with the published research and references.

Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.
For what YK-11 is and what published studies have found, see our YK-11 guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units. Rules on buying and importing differ by country: read are peptides legal in the US? and see all suppliers serving the US.
How to spot a fake peptide supplier explains each of these in more detail, and third-party peptide testing covers what independent results can and cannot prove.
Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.
6 of the suppliers PepFinder tracks list YK-11 and are based in or ship to the US. The highest rated are Direct SARMS, Leo Research, Research Chemical. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews, with stores based in the US placed before those shipping in from abroad; nobody pays to be included or to rank higher.
The FDA treats research peptides sold for human use as unapproved new drugs and has said in 2026 warning letters that research-use-only labels do not change that. Our page on whether peptides are legal in the US sets out the rules with a link to every source. This is general information, not legal advice.
The FDA says it is illegal in most circumstances for individuals to import drugs for personal use, and shipments it considers unapproved drugs can be refused entry. Each supplier on this page shows where it is based, so you can see whether an order would cross a border.
Ask for a certificate of analysis for the batch being sold, and check that it names the laboratory, the batch number and the test date, and that it confirms identity by mass spectrometry as well as purity by HPLC. PepFinder has not yet collected certificates for YK-11 from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list YK-11 on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score. Prices, sizes and stock are as each site listed them when checked and may have changed. Provisional scores are based on incomplete research.
