I started using no-xplode back when it first came out and it was the best. But I don't get the same reaction anymore like I used to. Now I take mr.hyde preworkout and stack with noxygen from purus labs. Works great.
I first started with Hemo-rage black, it was awesome.
Then my friend recommended GAT nitraflex as it was promoted as a test booster too, didn't boosted the test, but it was also good pre-workout.
Now I am using 1m.r. heard so many good reviews about it, its not that good in my opinion.
The best pump I have ever had was from lgi fully loaded. Amazing profile of ingredients and no proprietary blends, you know exactly what you are getting. Only thing it's missing is some creatine, which is cheap enough to add to it. As a pump junky, I like to add a few potassium nitrate caps to my fully loaded.
