Osta Rx by IronMagLabs | 90 Caps (Ostarine SARM)

All the benefits of prohormones without the side effects!

Osta Rx™ is a Selective Androgen Receptor Modulator, also known as a SARM. What is a SARM? This is a compound that can stimulate the androgen receptors in the body, the same way that anabolic steriod does...but Osta Rx is not a steriod. This compound is a select agonist which has been shown to have positive anabolic effects on muscle and bone tissue. It has been shown to have the same effect as testosterone.

Many customers take this product with their prohormone cycle because it can help increase your body's libido, testosterone and help you hold on to the mass and strength. We do recommend taking a PCT or Estrogen Reducer with this product.


  • Decrease body fat
  • Increase lean body mass
  • Increase strength
  • Increase libido

Directions / How to Take

Take 1 to 3 capsules per day spread evenly throughout the day. Take in cycles of 4 to 8 weeks. Do not exceed 8 weeks (You will need two bottles for an entire 8 week cycle). Before taking another cycle, take a break of at least 8 weeks. Do not exceed 3 capsules per day.

Osta Rx PCT - It is recommended to take a PCT/Estrogen Blocker with this product as it can increase estrogen levels. Gyno is rare, but to help prevent it, we recommend IronMag Labs E-Control.

Way to Take It

  • You can take it along with a prohormone cycle to help increase even more mass
  • You can cycle it alone to gain muscle mass, but not have the unwanted side effects with prohormones

Goal Recommendations

  • If you are looking to build up as much mass as possible over the 4-8 weeks, we recommend stacking this with Blackstone Labs Growth.
  • If you are looking to get cut and achieve that ripped look, we recommend adding Erase to your cycle (this can also take the place of E-Control).
