Good product
Works good if you're consistent in taking them. Goes down smooth if you take with water or juice. Should boost your energy level if you are consistent. No taste if it never touches your tongue and if it does, not a big taste.

reliable brand
I’ve been a loyal customer of this brand for years, and it’s one I genuinely trust. I’ve tried a bunch of their products and never felt disappointed—everything has always been solid and reliable. These BCAA capsules are no exception. I know BCAAs are something you can usually get from a well-rounded diet, and for the most part, mine is pretty balanced. But I still like having these on hand, especially on days when I’m training harder or just want that extra peace of mind. I don’t take them daily, but when I do, it’s more about making sure my body has everything it needs to recover and feel supported. The capsules are easy to take—no weird taste, no upset stomach—and it’s just convenient to toss a few into my gym bag if I’m on the go. For me, it’s not a must-have every day, but it’s a reliable backup that fits well into my routine when I need it.

I have found that while taking these I can see the difference in my body's recovery time and I can tell it has helped with my muscles. I can also say that I've been supplementing with them through the last few months and everything is going well. I also eat well, work out hard, and use other vitamins and supplements. An example of one of these supplements is . It helps keep my weight in control and interacts very well with everything else I take. It's not a magic pill but if you use it as directed and workout then you will definitely see results like i have.

Pris avec Optimum Nutrition Serious Mass, je me sens en pleine forme et ne vois pas d'effets secondaires "style hyper activité ou trouble de sommeil"... un bon complément de vitamine pour être en forme pas plus j'ai commencé ces compléments (serious mass+ bcaa) avec 15min de sport intensif par jour et en 15 jours, je suis passé de 54kg à 59kg pour 1m75 Donc à poursuivre jusqu'à 65kg + des scéances de plus en plus long... doucement mais surment

This works to remove muscles pains after hard exercises . I take them straight after omg I have done too much exercises and next day I never experience any pains . Sometimes my club pushes us far too much or I had taken too many classes in a week . I also sometimes overdone with machines . Last time I bought 400 capsules but no longer available and the price got slightly inflated but I cannot live without these ! My favorite. I can be brave for sports without worrying next day !
