I put on probably a solid 9 or 10 pounds

I put on probably a solid 9 or 10 pounds and kept them all after using 1 bottle. You almost get addicted to the gains because they come so fast, I was already committed and buying my second bottle after the first week. It's no joke and your muscles get super full and dense feeling. I can do more reps, max out higher and really felt the difference.

Got me to my goal weight!

Definitely got me to my goal weight. I was at 185 and couldn't get any further on my own. Took one cycle and reached 195. I will be getting more to help get bigger when needed.

Nothing compare to this!

This is the 1st true supplement in which I can actually call it an effective muscle builder. I've seen more and more of these "muscle builders" popping up lately but NOTHING compares to this.

Definitely this pro hormone works!

I just finished the cycle and have good feedback. I've gained about 14 lbs of muscle and strength was unbelievable. Definitely this pro hormone works!

Can't beat the effectiveness!

This is the only Prohormone I use. You simply can't beat the effectiveness and quality for the price anywhere else.
