Just to be clear I have to take all 6 capsules in one sitting?
Sylvester G on May 6, 2019
BEST ANSWER: Yes, I thought it was strange too, but can understand why now. It lasts much longer and I can tell the capsules are well done in the time-released state where I can feel the effects advertised much longer, smoother, and efficiently than others that require one or two.
why 6 capsules? It seems too much compare other products same brand.

Can you drink C4 SHRED powder mix with the capsules?
BernardF on Jun 15, 2019
BEST ANSWER: I would not recommend. I have used both in the same day but spaced them out. My usual routine is 2 capsules in the morning 2 capsules at 10am and 2 capsules at noon. On workout days after I am done working for the day I may drink a half serving of the powder.
