If you want lean muscle mass then BCAA supplements are a must. While there are many options in the market including some good Indian brands like Muscleblaze i personally trust BSN Amino X for several reasons. It comes highly recommend by lifters across the globe. The Amino content per serving is also good but the best part is the TASTE. This product is absolutely yummy although the watermelon flavour tastes a bit like blackberry. It mixes well and is effervescent so you feel as if you are having a soda. Easy to mix and tasty and super effective. I combine this with my Whey Isolates and have one serving before workout and one post. Just wish the pricing was more competitive but then i cant really complain considering that this is a 100% genuine product on HK. You will see similar product at lower price on amazon etc but i wouldnt take a risk with the genuinity of my supplements ever. Do HK it is even its pricey. Overall if price isnt a concern then pick this BCAA over any other.
