well, i used alot of EAS's stuff when i first got into the scene 7 years ago, but then made the switch to Muscle Tech, and have kinda stayed with them until this point...
i'm using some of BSN's products at the moment as well...
Gaspari Nutrition, Biotest, Optimum Nutrition, Max Muscle, Univeral Nutrition are great. From all the good that I'm hearing I have to try Beverly International
SciFit, Higher Power. For my multi its Pure Essence. My Protein powder its IDS. Preworkout its Nutrabolics Ester Stack. Prima Force for my HMB. Many researched months in my array of sups.
Optimum for bulk whey protein. But Beverly for quality and taste!!! Many people have posted that all companies are scammers and have products that don't work. I know Beverly's whole catalog, and I have yet to see a supplement of theres be a scam. They don't come out with stuff much, but when they do you better believe it is backed my science! Primaforce/ Scivation has some good protein isolate that sits easy on your stomach after a workout. I hate chocolate/vanilla after a workout so I get grape from primaforce.
