I recently invested in some Kre Alkalyn 1500 - have to say that this stuff is very good, my reps are much more productive and im recovering a lot faster whilst in the gym (though squats are still the enemy)
Much much easy to take, more effective than other creatine products iv tried previously and ok price.
Now I just need to find a protein/high calory powder that i'm happy with as going completely off USN stuff.
Just get fine powdered oats and some whey and smash them together with some peanut butter and some good oil/flax seed.
See there is a new jack3d out without DMAA. Tempted
