i started dtp yesterday as part of pct of a 9 day cycle that i ended due to too quickly losing libido. this post is for those that may have had a concern about the stims in the product, especially yohimbe. let me tell you that i am very stim sensitive and avoid them like the plague other than the caffeine in soda. yohimbe forget it i wont touch it. this product i was determined to try as i bought 4 bottles. i can tell you the stim effect is very minimal if at all. i took one pill first then 2 there after. i will try 3 tommorow pre workout. did not bother me one bit. i will be ordering 10 more bottles so that i dont run out anytime soon. i love it. the reason i love it is my willy was going on me quickly from the 9 days. i had the urge but no go for 2 days. 8 hours after taking 1st dose i was good to go. im a believer in this $hit and so is the gf
