YK-11 Peptide For Sale

How Researchers Actually Dose YK-11

Across 1 YK-11 calculator runs logged by the WPA community, the most common dose entered is 2mg, most often once weekly. The size researchers calculate against most often is the 100mg vial (1 runs). The most common bacteriostatic water volume is 2mL, 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. Every YK-11 vendor in the table on this page is screened for a published third-party Certificate of Analysis (COA), which is your one objective quality check.

How do I verify a YK-11 COA so I'm not getting an underdosed vial?

A Certificate of Analysis (COA) is the third-party lab report for one specific YK-11 batch — your only proof the vial is real and full-strength. Check four things: identity (it's actually YK-11, not a substituted SARM or an underdosed capsule), assay/purity (ideally 98% or higher), a named independent lab (not the vendor's own in-house claim), and a recent test date. WPA flags COA status per listing, but a marketing screenshot isn't enough — open the actual COA on the vendor's site before paying. Every row in the table links straight to it.

Which YK-11 vendor should I pick?

There's no single "best" YK-11 vendor — it depends on what you weigh most. WPA ranks every verified vendor by a composite of assayed purity, COA recency, lifetime click popularity among researchers, final price, and in-stock plus discount availability. YK-11 is dosed low, which makes underfilled capsules easy to hide, so favor vendors whose COA confirms the per-capsule milligram amount. If you just want the strongest all-round value, the top-ranked YK-11 vendor on this page is a safe starting point — but confirm its purity and price fit your protocol first.

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 every verified listing to $/mg, and the live cost-per-month card estimates your real spend at the most common dose, so overpaying becomes obvious at a glance. 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 1 YK-11 calculator runs logged here the most common dose is 2mg once weekly; 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.
