Our Most Popular Seller Since the Prohormone Ban of 2014!


This is the long awaited SARM supplement from Blackstone Labs. What is a SARM. It stands for Selective Androgen Receptor Modulator. What does that mean? This supplement has the ability to stimulate the androgen receptor. And this is a big deal because? Well, this is the same thing that steriods do! But the positive note is that they don't come with all the same side effects that steriods do.

Ostarine was created to help prevent muscle wasting. And as mentioned earlier, Ostarine causes muscle growth just like unapproved substances do! But with out all the side effects

  • For Men and Women
  • Does not Aromatize
  • Helps Heal Joints
  • Non-Toxic
  • Great for Recomping

When & How to Use It (Directions)

Directions - The best time to take Ostapure according to Blackstone Labs is while bridging two cycles of prohormones. You can also use it during a prohormone cycle. Along with men, women can also take this SARM. But, they should use this product at a 1 capsule reduced dose per day. It can be used as a performancing enhacing supplement for them.

Lean Muscle Gains

Most users experience 5-6lbs of muscle per cycle. They compare it to the effects of Alpha-1 Max.

Weight Loss

If you are looking to stay away from prohormones, but still want help with losing weight and getting ripped, Ostapure is perfect for that. You will keep your pumps in the gym, your strength and even boost libido.

Blackstone Labs Directions

Men: Take 1 capsule up to 3 times per day. Do not take for more than 12 weeks without 2 weeks off. Most users take for 6-8 weeks.

Women: Take 1 capsule per day. Do not take for more than 12 weeks without 2 weeks off. Most users take for 6-8 weeks.

With some users, it can increase estrogen levels, so as a precaution, we recommend adding Blackstone Labs Eradicate about 1/2 through your cycle. Not only will this stop an estrogen increase, but it will also help with dropping water weight/fat and increasing sex drive.
