Customer Ratings & Reviews

Branched-Chain Amino Acids is rated 4.7 out of 5 by 20.
Rated 4 out of 5 by from Maybe effective I'm 72 years old. Can't tell for sure if this product has helped with muscle building but I have noticed some increase in muscle definition. It could be that the product is complementing my gym exercise routine. If you decide to try it give it at least 6-8 months to see if you notice any results.

Rated 5 out of 5 by from Branched-Chain Amino Acids I have been taking these amino acids for about a month now and I notice a difference in my thinking, it's more clear. I take these along with Hemp protein powder. Will purchase again and again.

Rated 4 out of 5 by from Great Energy for Workouts I'm not sure if these did anything for my metabolism or fat burning yet, but they do provide me with some extra oomph if I take them before the gym or before heading out for a run.

Rated 5 out of 5 by from Great BCAA Best pure BCAA product and price you can find anywhere. If you like BCAA's, this is the best value and quality I've come across. Period.

Rated 5 out of 5 by from Appears to be good quality Appears to be good quality, I tried it myself and it does seem to be every bit as potent/effective as a different, more expensive brand I bought in the past. That's bound to be somewhat subjective, but that's my impression. I hope that helps.

Rated 5 out of 5 by from getting buff at 72 I've been a fitness buff most of my life. At 72 years of age i am extremely pleased with the results of adding the branch chain aminos to my diet regimen.I've added 10 lbs. of muscularity to my frame since adding the B.C.A.'s before and after each weight training session, in addition to a protein shake or 2 daily.Swanson B.C.A.'s rock.

Rated 4 out of 5 by from Great buy! It's the best price on the internet for BCAA's hands down. If you're working out for gain, this is the best product to have on hands. I just cant get over the value, seriously.

Rated 4 out of 5 by from This stuff is good I hate to review a product too early but I will do my best. I began taking Branch Chain Amino Acids for testosterone. I'm not a body builder however I'm using it to raise testosterone naturally. Because this review is so soon I have only noticed so far, my muscles are not as sore after workouts and a tiny little difference in my stamina.

Rated 4 out of 5 by from great product...but not for me Branched-Chain Amino Acids gave me a boost during my marathon training. I noticed a definite improvement in my recovery after long runs. Unfortunately, I had an allergic reaction to it and ended up sending it back. FYI: After speaking to my doctor, I did some research and found out people with allergies tend to have some kind of side effect when taking BCAA.
