Blackstone Labs Ostapure Stack



Blackstone Labs Ostarine Ostapure Stack (Discontinued)

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 unapproved substances do.  The good thing about Ostapure is that it does not have all of the same side effects that unapproved substances 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.

  • 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
