ULTIMATE MASS STACK

T.U.M.S. IS AMAZING!!!

I’m 37 years old. I have been on T.U.M.S. since June 25, 2025 and I must say the results are really solid! I’m going for two consecutive cycles and finishing with a four week cycle of a PCT Alpha-AF to maximize my results.

I most likely reorder two cycles of T.U.M.S. and one cycle of Alpha-AF when I’m off my current cycle and have waited an additional 8-10 weeks.

Significant results

This product has yielded significant results in the areas of strength, stamina, and growth. Only negative (if a negative at all) is I am always hungry.

This stack really is the ULTIMATE

This stack will really pile on the mass. If you only try one stack - make it this one. Be sure to follow up with Alpha when finished with the stack.

Great Stack

I recently suffered a spine injury. It has taken me a while to get back to a consistent training routine. Once I did I planed on taking this or the ultimate shred stack (used before and it’s also fantastic). This mass stack has blown my expectations away. The power and strength I have gotten from it has been unreal. The mass I have put on, has me almost where I was before the spine injury. Love this stack!
