[Met-Rx] Nitropump NOS

Nitropump NOS [Met-Rx]: I ve been using nitro pump for about 2weeks and love the increase in energy! - provided you stay well hydrated for it to work!
I ve read that it takes 3-4 weeks of use to work at optimum levels for growth, and also that it arginine is a good fat burner.
Are both these facts true - because I m trying to kill 2 birds with 1 stone, by using the 1st month to load up on nitro pump, whilst hoping the arginine will help to shed some body fat in that time along with good diet & cardio, before using heavier weights in the building phase of training after that 1st month.
If the loading phase is true but the fat loss part isn t, would it safe to use the Yellow 25X fat loss caps as well as nitro pump I ask this cuz I already get a slight sense of euphoric/ stonedness with the energy pump from the nitro, but have read there s also this kind of increase when using the Yellow 25X s.
Ive used ephidrine extensivley in the past so feel the effect of the Yellow 25X caps on their own isn t a problem, but dont want either have a heart attack or get knocked over crossing the road whilst buzzing on cloud 9!
Cheers for any advice you can throw my way - it s my 1st use of this Q&A facility - I think it s a quality service for novices like me on a tight buget, whilst hopefull of results with just 1 or 2 supplements.

Nitro pump works from day 1, however the effects accumulate and peak at around a month of continued use.

Whilst the amino acid Arginine is helpful for fat burning due to its ability to help increase growth hormone, its effectiveness as a fat burner is limited.

Yellow 25X is very powerful, and in line with previous products you have used, so the effects would be as youve experienced before.

If you want something that works, but is milder on the system, look at the Ultra Lean FX by Biorhythm.

PS. Thanks a lot for the positive feedback, much appreciated
