These products would stack perfectly together. Post your diet and training goals along with current body type, weight, height and body fat %. This will help us gauge appropriate dosing and assist in forecasting your results.
I would not double dose PRIME. The recommend dose is 2 pills, 3x per day (with meals). If you are heavier that ~200lbs, you could dose 3 pills 3x per day.
There are no side effects or even warrant for me to warn against double dosing but it is recommended to follow the giving dosing instructions.
I look forward to your reply so we can get this all layed out in the most effective manner! :cheers:
