Blackstone Labs Ostarine Ostapure Stack

For those looking to increase muscle mass and strength with no side effects!

Blackstone Labs Ostapure is a SARM supplement which stands for Selective Androgen Receptor Modulator.  This means that this supplement has the ability to stimulate the androgen receptor, which means it does the same thing that steroids do.  The good thing about Ostapure is that it does not have all of the same side effects that steroids have.  Most users experience between 5-6 pounds of muscle per cycle.  Ostapure helps increase your pumps in the gym, strength, and libido.    

Blackstone Labs Eradicate increases natural testosterone and lowers levels of estrogen in the body.  It helps increase sex drive while reducing water retention and eliminating the chance of gyno.  It should be taken as a PCT to bring hormone function back to normal.  Eradicate is a suicide aromatase inhibitor which means it binds to the aromatase enzyme and cannot be reversed.

  • As a dietary supplement, take one (1) capsule three (3) times daily in divided doses per day, with food.  Use in cycles of 4 to 6 weeks taking at least 2 to 4 weeks off in between cycles.


Most users take Ostapure for 4 to 8 weeks, though you can take it for up to 12 weeks. If you choose to take it for 8 weeks, you will need 2 bottles. Take 3 capsules per day. Then you have some options on how to take the Eradicate:

  • Start the Eradicate 1/2 way through your cycle (if taking Ostapure for 8 weeks, start Eradicate 4-5 weeks in)
  • Take Eradicate throughout your entire cycle (not recommended for 8 week cycles)
  • Take Eradicate during your PCT only

yeah i gained a little bit of muscle but it wasn't marginally greater than if i were to be training naturally. I got a lot of side effects though, notably: serious gyno and a lot of bloating. My libido also crashed and I got constant head aches throughout the day.

I am 4 weeks in and wanted to give an update. I have gained almost 10lbs so far. Mostly muscle, I would say maybe 1-2 pounds of fat or water. I am lifting more too. Libido it up. I plan on using it for 2 or 4 more weeks. Blackstone Labs recommended I begin my Eradicate pretty soon here, though I don't have an estrogen issues...still going to use it to be safe. Oh...and my girlfriend just started using it too. Lower dose, but I will have her review her experience in a few weeks.

Read about this product on Blackstone Labs and they recommended their estrogen supplement too. This one was way cheaper for the stack and it's working great so far. I am up in weight, my strength is up and so far no issues with estrogen. Highly recommended.

Awesome stack. I was worried about estrogen build up and gyno, which people warned about in other forums. This stack had the estrogen blocker in it and after 8 weeks of usage, absolutely no gyno and estrogen build up in the nips. I am very happy with it. 6lbs of muscle so far and plan on using it for another 4 weeks.
