What Zionova MK-2866 is
MK-2866 is ostarine, also called enobosarm, the most studied SARM. Each Zionova tablet contains 10 mg, with 50 tablets per bottle. Ostarine reached phase 3 trials for muscle wasting in people with cancer, and it’s the SARM with the most human data.
Those trials used doses far lower than what’s commonly sold. Ostarine is also the SARM most often behind failed drug tests, sometimes through contaminated supplements. Here’s what the research shows.

How it works
- Selective androgen receptor activation in muscle and bone, with less effect on the prostate than testosterone in early studies.
- No conversion to estrogen or DHT.
- Half-life about 24 hours, so it’s taken once a day.
In a phase 2 trial, older adults taking 3 mg a day gained about 1.3 kg of lean mass over 3 months. Phase 3 trials in cancer patients didn’t meet their main goals.
Side effects and risks
Trial doses were well tolerated; most problems are reported at much higher doses.
Testosterone suppression
Even trial doses lowered testosterone and SHBG somewhat; higher doses suppress more.
HDL cholesterol
Trials found HDL fell with ostarine.
Liver
Case reports describe liver injury in people using ostarine at bodybuilding doses.
Drug tests
Ostarine is one of the most common causes of positive doping tests, including through contaminated supplements.
Unknown long-term effects
Trials lasted months, not years.
Don’t use it if you
Are under 18, pregnant or breastfeeding, have liver disease or high cholesterol, or compete in tested sport.
Bloodwork checklist
Test before you start, at 4–6 weeks, and 4 weeks after you finish.
- Liver panel
- Lipid panel
- Testosterone, SHBG, LH, FSH
Dosing information
Clinical reference. Ostarine isn’t approved. Clinical trials used 1–3 mg a day, for up to about 5 months.
One Zionova tablet is 10 mg, more than three times the highest trial dose. Every risk on this page rises with dose. Talk to a doctor before use.
Post-cycle therapy and support
At higher doses ostarine suppresses testosterone. If bloodwork afterwards shows low levels, a SERM such as tamoxifen (Nolvadex) or clomiphene (Clomid) is commonly used. See Pairs well with below.

Common questions
Is ostarine the mildest SARM?
It’s generally considered one of the milder ones and has the most human research, but it still suppresses testosterone and lowers HDL, especially above trial doses.
Do I need PCT after ostarine?
Not always. Bloodwork after the course tells you whether your testosterone has recovered on its own.
Is ostarine approved anywhere?
No. Despite reaching phase 3 trials, it hasn’t been approved as a medicine.
How fast is shipping in Canada?
Orders placed before 2 PM EST, Monday to Friday, ship the same business day by Canada Post Xpresspost, with tracking.
Is ostarine legal in Canada?
Ostarine isn’t approved by Health Canada, and Health Canada has warned about unauthorized SARM products. It’s banned in tested sport.
How is my order packaged?
In a plain, unbranded box with no product names on the outside.
