Ok I'll start with Fierce. Fierce tasted really good first of all!. Great orange taste, reminds me of orange tang!. Mixes well too. Nice and clear. I didn't notice any energy at all while using Fierce. In fact I felt really relaxed, so much so that I almost didn't want to work out. I think there may be something in this that makes me feel sleepy. The last thing I tried that made me feel like this was GlycineHCL. So I'm guess the did this to me, specifically the nitrates.
Ok with Launce Full Impact 4350 I used it pre-cardio. It has the Nitrates in it also but more stimulants that may off-set that relaxed feeling I think I'm getting from nitrates. This product also mixed quite well and was extremely tasty orange flavor also!. I did feel that relaxed feeling on the Launch 4350 also....But I had energy to push through my cardio like nobody's business. One thing I noticed though is that my heart rate, according to the cardio machine was 20-30 points higher than normal. That may have just been because I was able to push harder and go faster though. I didn't feel cracked out though which is a good thing because certain stimulants do that to me and it is no fun. After I finished my hour of steady state cardio I did so back extensions and noticed I had to rest longer between sets because my heart rate was much higher than normal. That slowed down the weight lifting part of my workout. I do some back and some abs with machines on my cardio days. Anyway, I would use the Launch 4350 again, just pre-cardio because I feel it shines there. With weights I wouldn't use either the Fierce of Launch 4350.
Maybe I'll try the Launch again and see how it goes, but of the two product I have to say Launch is the better one.
Thanks to SANN for the samples.
