Hope i'm posting this in the right room... I've only taken Creatine, been cycling it on and off basically for parts of the last 15 years while I lift. I have been told Cellucor P6 as a testosterone booster will help with strength gains. My friend has done the 90 day stack with red and black.
Any feedback? Are there better entry points into testosterone boosters? More effective? Less side effects?
Open to suggestions.
