Hi Dylan. I recently bought Rad- 140. I have a few questions. 1st do i need any on cycle with this. I'm doing 30 milligrams a day. And I'm also taking an andro supplement. It's called Spartan mass by Spartan nutrition. Is it ok to stack the rad-140 with this? . The Spartan mass is basically 1 andro and 4 andro together. Theres 100 miligrams of 1 andro and 100 of 4 andro. Is it safe to stack this with the sarm I'm taking. I'm curious and if it is do i need a on cycle support? I have been making some good gains. Especially strength.
