Can one use USP labs Jack3d while using the Trifecta Stack or Natadrol Stack?
Absolutely! As mentioned, watch the BP but that prework on that stack should yield nice results!
I have absolutely nothing against USPLabs... LOVE ME SOME OEP!!!!!
I had used Jack3d for MANY months and liked it. I transitioned to ASTG AND LOVE IT!!!! Whole nother animal and the best preworkout I have ever used.
I am sure either will work fine but dollar for dollar, my money is on the ASTG. Ran it with Natadrol and now with the PCT Formadrol.
