Benefis of taking XTEND Original BCAA:

BCAAs are commonly used in the fitness and athletic training world. Some of the potential benefits described by manufacturers include:



  • Performance improvement: BCAAs are essential for muscle protein synthesis, so they are believed to help improve performance during training.
  • Reduction of muscle pain: Some studies suggest that BCAAs may help reduce muscle pain after exercise.


  • Prevention of muscle loss: BCAAs may help prevent degradation of muscle proteins during intense training or during fasting periods.
  • Improved recovery: Some studies suggest that BCAAs may help improve muscle recovery after training.
  • It is important to note that although BCAAs play a role in protein synthesis and may have some positive effects, these have not been clearly demonstrated in large-scale research and may vary from person to person. Additionally, it is possible to get enough BCAAs through a balanced and protein-rich diet. It is recommended to consult with a health professional before taking BCAA supplements.

User reviews:

In general most of the reviews are good from users however there are also some not so good things: this is what people say:

1. @Yesica77 : 

"I bought this BCAA supplement to help with recovery from workouts. First time I tried it, I followed the instructions to mix two scoops into a glass of water and drank the whole thing. Super-sweet, but not awful. I then did a heavy weightlifting workout without problems.

That evening, however, I began to feel a migraine headache coming on. By the next morning, it was hitting me full force. It lasted roughly 36 hours.

I did some research that revealed BCAA's can trigger headaches in some people. Some other reviews of this product note that it triggered headaches.

But... my post-weightlifting soreness was noticably better. That's a big deal for me. When I lift heavy weights, I usually get a ton of soreness that can last several days. After consuming a full dose of this stuff, I had a headache, but experienced almost no soreness in the days following my lift.."

2. @Jhon Ruiz: 

"I had this product before and it does the job, it works for me but what Amazon is doing is sending the product that is about to expire! I do not understand if I ordered a product that contains tablets that will last for a year, and we have to take 2 a day? why send a product that is about to expire?."

3. @Noele:

"This lasted a long time for me, and it doesn’t taste bad at all in my opinion. And I just mixed with water. Usually drank it before and during my workout."
