Great Supplements

I love the Supplements from Bulk Supplements. Their supplements don’t have fillers and always arrive at my house sooner than expected.

first purchase from this company

Easy ordering process at a fair price and shipping speed was excellent. One issue that needs to be corrected is the bag. The contents were all up in the top of the bag where you have to open it. So you obviously try to push it down to bottom of the bag, but there is still quite a bit at the top and when you open it the powder goes everywhere making a mess and losing product you just paid for. The bag needs an inner where the product is kept with the zip lock above it.

So far so good. Just started using it.

No issues. Ordering was easy, shipped quick and intact. HMB isn’t one of those supplements you can ‘feel’ working so I can’t say much yet.


Works reasonably well

I bought this product as a way to maintain muscle mass and strength when I wasnt training. Thats exactly what happened this summer when I took up a full time gig before the start of university in the fall. I had very little time to go to the gym so I skipped a number of workouts but I was consistently taking HMB and creatine and I was able to maintain a steady weight and didnt experience a noticeable loss in muscle mass. My strength was more significantly impacted by a lack of training but I suppose it has more to do with neurological adaptation than muscle mass. Regardless I would recommend this for anyone that plans on taking a break from the gym but doesnt want to lose all the fruits of their labor.

Great Value, but be careful

Be careful mixing with water. Will gel quickly. Best mixed with other powders. Take only a small amount with other mixtures. I take with Collegen &Glysine blended with Psyllium. Seems to work well, but I would down it quickly before it gets too thick. Small bag (100 grams) goes a long way.
