I have been running EST Plasmatic and Methylmass and it has been INSANE! My pumps, endurance and strength has increased dramtically. It is by far the best supplements I have ever taken for preworkout. Also the MethylMass mixes very easily, does not have the very sweet taste that makes you sick during your workout and it taste awesome! Cotton Candy is the best so far to me.

I give this stack a 10/10 without a doubt.

I used to be a fan of Superpump250, NOSHOTGUN, and Supercharge but the price was out of my range and I would witness a crash with some of them.
