I'll post this in the product review section as well. Thanks Marms!
First off, I want to thank Lecheek for the opportunity to log Speed X3. Unfortunately, I don't think this supplement is for me. I think I'm sensitive to Yohimbe and the amount of Yohimbe in there was just too much for me. There is also a third stimulant of Synephrine HCI, making Speed X3 very potent. I only took a full dose (1 scoop) on an empty stomach once. I experienced extreme energy, my heart was pounding, and I remained on edge for quite a while post workout. During the workout I felt like I was running around a mile a minute. The tunnel vision was so intense that I wasn't even able to jam to my music. With Speed X3 being touted as an energy supplement, I was hoping that it would be versatile enough to take for cardio. However, I was unhappy with my experiences when taking with cardio. Anytime I ramped up the intensity, my breathing and heart rate seemed to get out of control. Therefore I only used it for steady-state easier cardio days. I also don't recommend using Speed X3 when you know you'll be exercising in hot temperatures. There is a definite thermogenic effect with this product. When I dosed it close to a full scoop, I noticed a warm sensation at the start of the workout and increased sweating throughout the rest of the workout. After taking for a while, I did find my sweet spot with the supplement. I would start by taking extra caffeine (50-150mg), .5g Beta-Alanine, 1g Taruine. Then a little later, I would take half scoop Speed X3 with 20-25g whey. Mixing it with whey seemed to minimize the negative side effects for me. Unfortunately with a half scoop, I wasn't getting as much of the performance enhancement properties, just pure energy. No matter the dosage, I always experienced great endurance and recovery during lifts. I always had plenty of drive left at the end of workouts. For me, I enjoyed Speed X3 the most when I took longer rests between sets ( > 90 secs), otherwise my heart rate would get out of control and I would feel like I was running around. I cannot say it helped much for pumps because I was normally dosing it at a half scoop. I didn't experience any extra rage while taking this. On some other PWOs, I feel like I want to run through a brick wall, not with Speed X3, just extreme energy and tunnel vision. I was able to see some performance gains while on Speed X3.
So to sum it up, I'll give it a 3/5. My sensitivity to Yohimbe really decreased my satisfaction for Speed X3. Although, it makes a really good value when dosing at a half scoop. However, I am looking for a little more in a PWO than just pure energy. If you are not sensitive to Yohimbe, I would definitely recommend giving this a try. This would also be a good alternative to Red Bull.
