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.
02Molecule
The molecule
What is actually in the vial or tablet, from the public chemistry databases of the U.S. National Library of Medicine.

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.
