ok everyone, i have ran this puppy for a full week now. i have ran it from high carbs to absolutely zero carbs. so here is my review on a great product:

product strength: full 5 (great pumps and full muscle)
product stim full 5 (now if you are looking to be cracked out this is not the product for you. this is a clean steady energy)
product taste 5 (taste is very good no after taste at all which is always an added bonus)
impact on libido 5 it has no affect and hasnt caused in stim dick
ease in digestion a big 5: (no running to the toliet to piss out your butt within minutes on this one or 45 minutes after taking for that matter) no jungle shits at all
product tolerance 5 (so far this is a 5. no need to increase the dose for the same effects for my full week run when normally you adapt in 3-5 days. i will return and update this again each week to see if it occurs at all

so overall i rate it as a 5 star product that is great. it gives what it advertises, nice smooth clean energy that lasts through the entire training session, no jitters, no crash and nice mood and focus. i will back this product for anyone that likes a good preworkout to try
