01The basics

What YK-11 by Genetix Pharma is

YK-11 is an experimental compound with 5 mg per tablet and 50 tablets per bottle. It’s usually sold as a SARM, but chemically it’s a steroid, built on the DHT skeleton, that acts as a partial activator of the androgen receptor.

Its reputation as a “myostatin inhibitor” comes from a single line of cell culture research. There are no published human studies of YK-11 at all, so effects, dosing and safety in people are unknown. This page sticks to what’s actually been shown.

03How it works

How it works

  • Partial androgen receptor agonist: it activates the receptor, but differently from testosterone or DHT.
  • Follistatin in cell studies: in muscle cells grown in a dish, YK-11 increased follistatin, a protein that blocks myostatin (a brake on muscle growth). That hasn’t been shown in animals’ muscles or in people.
  • Steroid structure: because it’s a modified steroid, many of the same concerns apply, including possible suppression and liver strain.

04Clinical reference

Dosing information

Clinical reference. YK-11 has never been tested in people, so there’s no clinical or trial dose.

One Genetix tablet is 5 mg. Every risk on this page likely rises with dose and duration. Talk to a doctor before use.

05Measure it

Measure it

Type in the amount your prescriber gave you, or the one you are working from, and this turns it into what to draw up or count out from this exact product. It only does the arithmetic; it never suggests an amount.

06Risks

Side effects and risks

With no human studies, YK-11’s risks are largely unknown.

Testosterone suppression

Users commonly report suppression; as an androgen receptor activator, it’s expected.

Liver

Its structure and oral route raise liver concerns. Get a liver panel.

Cholesterol

HDL reductions are likely, as with other androgens.

Hair and joints

Hair shedding and joint aches are reported by users.

Unknown long-term effects

Nothing is known about long-term use in people.

Don’t use it if you

Are under 18, pregnant or breastfeeding, have liver or heart disease, high cholesterol, or compete in tested sport.

07Interactions

Interactions

Medicines and substances that change how this product behaves, or that it changes. Show this list to your pharmacist along with everything else you take.

  • Good to knowNo interaction studies

    SARMs were never approved, so they were never tested against other medicines.

  • CautionOral steroids, alcohol and acetaminophen

    Liver injury has been reported with SARMs; anything else that loads the liver adds to it.

  • CautionAnything that lowers HDL

    SARMs reduce HDL cholesterol; oral steroids lower it further.

08Bloodwork

Bloodwork checklist

Test before you start, at 3–4 weeks, and 4 weeks after you stop.

  • Liver panel
  • Lipid panel
  • Testosterone, LH, FSH
  • CBC

09After a course

Post-cycle therapy and support

If bloodwork shows suppressed testosterone after a course, post-cycle therapy with a SERM such as tamoxifen (Nolvadex) or clomiphene (Clomid) is commonly used. See Pairs well with below.

12Questions

Common questions

Is YK-11 really a SARM?

It’s marketed as one, but it’s built on a steroid structure. “Steroidal SARM” or partial androgen agonist are more accurate descriptions.

Does YK-11 block myostatin?

In cell culture, it raised follistatin, which blocks myostatin. Whether that happens in human muscle hasn’t been studied.

Is YK-11 banned in sport?

Yes. It falls under the World Anti-Doping Agency’s prohibited anabolic agents.

How fast is shipping in Canada?

Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.

Is YK-11 legal in Canada?

YK-11 isn’t approved by Health Canada. Health Canada has warned consumers about unauthorized products sold as SARMs.

How is my order packaged?

In a plain, unbranded box with no product names on the outside.
