YK11 Suppression | Intensity, How It Feels And More!

As I already said in my SARMs testosterone suppression write-up, YK11 is one of the most suppressive SARMs in existence.

With YK11, you’ll definitely have to use SERMs as a PCT and do blood work, those two are necessary to prevent a complete testosterone shutdown.

YK11 Suppression Intensity

YK11 suppression is usually moderate to heavy in nature and you’ll be hard pressed to avoid it, even when imbuing low dosages.

This means that even 5mgs per day of YK11 can lead to a complete testosterone shutdown.

With that being said, most people will experience heavy suppression from YK11 and they’ll need at least four weeks of PCT to recover from it.

There’s no denying it, YK11 is intense when it comes to testosterone suppression and the signs of it are quite obvious.

How Does YK11 Suppression Feel Like

YK11 suppression is quite “in your face” as I like to call it, since it suppresses the person completely.

You’ll definitely feel the suppression coming on the sixth or sometimes even fifth week of your YK11 cycle.

Symptoms are generally intense, with mood swings, aggression, depression and loss of libido dominating the playing field.

Unlike LGD 4033 suppression, which actually starts off as feeble and grows in intensity, YK11 immediately hits you with everything in its arsenal.

This means that you’ll wake up one day and suddenly feel depressed, lethargic and apathetic towards your usual interests.

Some people don’t expect that level of suppression and find themselves dumbstruck by the intensity.

There’s nothing to worry, as with proper PCT, you’ll be able to overcome most of the hurdles set by YK11.

It’s expected of you to do blood work before and after your YK11 cycle, so that you can see what hormones got hit the most by the SARM in question.

Be sure to look out for free and total testosterone, SHBG, FSH and LH!

How To Mitigate YK11 Suppression

By now, you have probably realized that there’s no stopping YK11 suppression; if you’re taking this SARM, suppression is coming for you guaranteed.

That’s why the best thing we can do is equip ourselves with SERMs, which help balance testosterone levels in the body.

I’m usually leery of recommending SERMs to anyone, as they have many side effects but in this case, it’s an absolute necessity.

The two most trusted SERMs in our arsenal are Nolvadex and Clomid.

To learn how to properly do PCT while on YK11, we have to consider a couple of things.

The most important factor is level of suppression; if you’re heavily suppressed, I personally recommend you go for Clomid, as it’s a bit stronger compared to Nolvadex.

However, if the suppression is moderate, go for Nolvadex, as it has less side effects.

You can buy both Nolvadex and Clomid at Spectre Labs, you’ll find the biggest coupon code and link to the site in my recommended companies.

The next thing to keep in mind is your tolerability of SERMs; that’s something you’ll have to find out yourself.

I think it’s best to just go for Nolvadex and see what happens, most people experience only mild side effects so it’s fine.

Regarding dosages and PCT length, read my SARMs PCT article, where I go in-depth on this topic.


YK11 suppression is nothing to joke about, so please take the advice in this article seriously.

Ensure that you do a blood test before and after your cycle, as that’s the best way to determine your level of suppression.

Lastly, don’t be afraid of YK11; there’s PCT available and thousands of bodybuilders have done it successfully!
