Ostazol (M1-MK) by Banned Nutrition


What is Ostazol (M1-MK)?

Introducing Ostazol (M1-MK) by Banned Nutrition, a hardcore testosterone booster that is taking the supplement market by storm.  M1-MK takes the hassle out of your on-cycle and post cycle supplementation because it has over 2 dozen ingredients.  No need to buy 25 different products from the overpriced retail store, now you can get it all in 1.

April-December 2020 UPDATE:

Banned Nutrition is now making m1-mk under the new brand name Ostazol (M1-MK).  It's the M1-MK version 2.0 with the amazing ingredients and more. What does this mean for you? Basically you get the same extract ingredients with the exact same bottle, the only thing that's going to change is the name, instead of saying M1-MK, the bottle now says Ostazol (m1-mk), so, really, only the word ostazol is added, no ingredients are changed guys.

Who should use it?

If you are currently, or want to become, a serious lifter in the gym you should use M1-MK.  It is a must use on any steroid cycle, during your post cycle, and safe to use in between cycles too.

Testosterone boosting

Testosterone is the male hormone that gives us muscle, strength, libido, and our other man-like features.

Women absolutely know the difference between a beta male with low testosterone and a true confident alpha male who has high testosterone levels.  Guess which man she will want to have sex with?  Bottom line is without healthy testosterone levels you cannot be a real man. 

Many of the ingredients in M1-MK help boost testosterone safely, without suppressing your own bodies production of hormones.


M1-MK works great on cycle because of all its antioxidants, libido boosting, and organ detoxing properties.  It also contains several ingredients that will help balance your estrogen levels too.  Remember estrogen is our female hormone, and many men suffer from high estrogen which means more fat, more bloat, and less alpha male qualities.

Post cycle therapy

After you use anabolics you must run a post cycle therapy (PCT) to prevent crashing and losing all your hard fought gains.  M1-MK contains ingredients that give you that 'on feeling' so you don't lose any confidence after you come off steroids.  It also helps you recover quickly so you keep your strength, muscles, and motivation.


Listed below are all the ingredients and amounts per serving.

what is m1-mk


M1-MK serving size is 7 capsules and each bottle contains enough to last 30 days or 1 month.  We recommend dosing the full serving of 7 daily on cycle and post cycle.

Off-cycle you can reduce the dosage to 3-4 capsules per day.  Also, it is a smart idea to split the dosages morning and evening to have a balanced amount in your system 24/7.

Suggested dose split is 1 capsule every 1 hour for 4 hours, followed by 3 capsules preworkout.  Preworkout: 1 capsule 1 hour before training, 1 capsule 30min before training, 1 capsule 5min before training.

Where can I read more about it?

Elitefitness.com and Evolutionary.org have logs with user reviews.

Where is it sold?

M1-MK is sold at bannednutrition.com; however, banned nutrition only distributes to brick and mortar stores and wholesalers now it seems.  It's a very niche high quality brand.
