How Researchers Actually Dose YK-11
Across 6 YK-11 calculator runs logged by the WPA community, the most common dose entered is 5mg, most often 2x/week. The size researchers calculate against most often is the 50mg vial (4 runs). The most common bacteriostatic water volume is 10mL, which is what sets the draw marks on the syringe for that dose.
About YK-11
YK-11 is a steroid-derived compound sold as a SARM and marketed as a 'myostatin inhibitor' — not a peptide. It is sold as a research chemical (capsules or an oral liquid) with no human trial data.
Its reported half-life is ~6–10 hours (estimate), which is the main reason the community cadence above looks the way it does. Not FDA-approved.
Frequently Asked Questions: YK-11
Is it legal and safe to buy YK-11 for research?
In the US, YK-11 is sold strictly as a research chemical — legal to buy for laboratory research but not approved for human use. It is an investigational myostatin-modulating SARM with no approved human use and a WADA ban in sport — sold for laboratory research only. The real variable isn't legality, it's quality: unverified suppliers can ship underdosed, impure, or mislabeled material. WPA records COA-related listing fields where supplied, but does not independently verify every report. Inspect the actual batch report and its laboratory, identity testing, and date before drawing conclusions.
How do I verify a YK-11 COA so I'm not getting an underdosed vial?
A Certificate of Analysis (COA) may report tests for a specific YK-11 batch. Check that the report identifies the compound (actually YK-11, not a substituted SARM or an underdosed capsule), names the laboratory, describes the test method and result, and matches the offered batch and date. A recorded purity value or COA-availability flag in WPA's listing data is not independent verification. Open the vendor listing and inspect the actual report before drawing conclusions.
Which YK-11 vendor should I pick?
There's no single "best" YK-11 vendor — it depends on what you weigh most. WPA ranks tracked listings using recorded purity and date fields where available, visitor click activity, price, stock status, and discount data; this ranking is not independent verification of a report. YK-11 is dosed low, which makes underfilled capsules easy to hide, so favor vendors whose COA confirms the per-capsule milligram amount. Review the actual report and confirm its batch details before making a decision.
How much does YK-11 cost — and how do I know I'm not overpaying?
Judge YK-11 by true price per milligram, not the sticker price on one vial — a cheap small vial often costs more per mg than a larger one. Compare cost per total milligram across bottles, not the bottle price, since capsule counts and strengths differ. WPA normalizes tracked listings to $/mg, and the live cost-per-month card estimates your spend at the most common dose. The one catch: the lowest $/mg sometimes means buying a bigger vial than your cycle needs.
How much YK-11 do I need for one full cycle?
YK-11 is taken orally, with research protocols commonly in the 5–10 mg per day range over an 8-week run. A 60-capsule bottle at 5 mg each covers about two months at one capsule a day, so a single bottle generally carries a full cycle. Across 6 YK-11 calculator runs logged here the most common dose is 5mg 2x/week; that is the figure the cost-per-month card on this page is built on. Protocols vary and this reflects the most common community setup, not medical advice — research use only. Use the cost-per-month card and the calculator on this page to size your exact run, then buy enough to finish a cycle without re-ordering mid-protocol.
Are discount codes available for YK-11?
Yes — many verified YK-11 vendors offer WPA researcher discount codes, and those savings are already baked into the $/mg ranking on this page, so you're never comparing a pre-discount price against a post-discount one. Codes do change, and some exclude sale items or carry order minimums. Each listing shows the current code and the discounted price where one exists.
