YK11 SARM IN CAPSULES
Description
What is YK11 by Biaxol?
Biaxol YK11 in capsules. Strong and fast at low doses, and methylated, so it runs in short blocks rather than for months.
Also sold as YK-11 or myostine.
YK11 is the odd one in this category, because it is not really a SARM. It is a steroidal compound built on a DHT backbone, and it is methylated, which is what lets it survive being swallowed. Alongside androgen receptor activity it is reported to inhibit myostatin, the protein that limits how much muscle you can carry, which is where its reputation comes from.
YK11 (Biaxol) benefits
- Reported myostatin inhibition alongside androgen receptor activity
- Rapid lean muscle and strength gains at low doses
- Dry gains with no water retention
- Short cycles, which limits total exposure
- One of the strongest compounds in this category per milligram
- Black pepper fruit extract included at 5mg per capsule, which improves absorption
YK11 dosage
- Per capsule
- 10mg, which is already a full dose
- Common range
- 5 to 20mg per day
- Cycle length
- 4 to 8 weeks
- Frequency
- Once daily
- Post-cycle therapy
- Required, plan it before you start
- Bloodwork
- ALT and AST, plus lipids
One capsule is 10mg, which is a full working dose rather than a starting one. If you have not run YK11 before, the 5mg tablets are the better place to begin.
Biaxol capsules include 5mg of black pepper fruit extract, which the tablet versions do not. That is the main difference between the formats.

Who is YK11 (Biaxol) for?
Advanced users who already know how they handle YK11 and want a full dose in one capsule.
YK11 5 is the 5mg tablet and the sensible starting point. The Astera version is also 5mg.
How to use YK11 (Biaxol)
Swallow one capsule with water once daily. Do not run it alongside another methylated compound and keep alcohol low.
Frequently asked questions
Do SARMs really need PCT?
Yes. This is the single most repeated piece of bad advice about them, and it costs people months of feeling flat.
SARMs are selective, not non-suppressive. A SERM such as tamoxifen or clomiphene is what restarts your own production.
Is YK11 actually a SARM?
Not really. It is a steroidal compound on a DHT backbone and it is methylated, which puts it structurally closer to an oral steroid than to ostarine or RAD-140.
That matters practically: the cycle length and the bloodwork should look like an oral rather than like a SARM, which means shorter runs and ALT and AST included.
Does it really inhibit myostatin?
That is the claim it is sold on, and it comes largely from cell culture work rather than from human studies.
The mechanism is plausible and the compound is genuinely strong. Whether the myostatin effect is what drives the results, or whether it is simply potent androgen receptor activity, is not settled.
Why are the runs shorter than with other SARMs?
Because YK11 is methylated, which is what makes it work as a tablet and also what makes the liver the limiting factor rather than tolerance.
Four to eight weeks, ALT and AST included in your bloodwork, and no other methylated compound alongside it. Treat it the way you would an oral.
What dose and how long?
5 to 10mg a day for four to eight weeks. Some run up to 20mg, though the returns do not scale with the dose.
Shorter is better with this one. It is potent enough that a four week block does something.
