Always goes bad

Every preworkout I've gotten, bulk and lean, never lasts to the expiration date and I have to throw out half of it because it turns into a clump and is no longer powder

Can't get through it

Good price and the effect is fine. But with the peach mango flavor, I just can't get myself to drink it anymore.

First time using

Just opened the preworkout and mixed for this morning’s workout. None of that annoying tingling or itchiness that I have experienced with other brands. Tasted good and mixed well in a shaker cup. I noticed that I got 0-2 reps extra on my work sets this morning. Very happy with those results!

Noticeable difference

As opposed to just going into my workout without supplementing, Bulk is a powerhouse that elevates my workout and helps me get that one extra rep. I am 42 years old and need to keep it simple and effective, and Bulk does just that under one supp. I love the tropical punch flavor.

Great Pre

Amazing high quality ingredients with many benefits, can feel a big difference using this pre workout. Also easier on the stomach due to the fact it doesn’t have a super high amount of caffeine or crappy ingredients. Very impressed overall.
