Dusty Delivery

When I opened the package containing the bulk supplement bags, my hands were coated in a white powder. I originally thought that one of the bags was broken. However, that was not the case. Not really certain how the powder got into the external package. This was the first time that this had ever happened.

High Quality

Good stuff. I've been powerlifting for two decades, and I started taking Leucine about 8 years ago. I noticed IMMEDIATELY that I was less sore the day after working out. It wasn't a small difference either. I've used Bulk Supplements Leucine the entire 8 years, and never been disappointed.

Smell is off, may have a bad batch?

I took a recommended dose of this as well as a recommended dose of N-acetyl L-cysteine (I bought them at the same time) and within a short time I became violently ill and threw up, which I haven’t done in years as I have a pretty strong stomach. The other supplements I’ve gotten here are all good, some have a slight gross smell or taste but nothing like this especially the N-acetyl L-cysteine smelled like death and I feel dumb for even choking it down. Now I’m afraid to take the l- leucine either because I don’t want to get sick again. Disappointing/maybe dangerous

Supp purchase

Speedy delivery though I was disappointed that you are consistently out of the package size I wanted. I checked a couple times and had to settle for the smaller package of Leucine.
