Good product but rarely in stock
I think this is an excellent product but it hasn’t been in stock for at least 4 weeks.  Hard to rely on steady use of a product if you can rely on a steady supply. Â

Not good bad batch
Received 500g of leucine. Â When opened I noticed a very foul smell. Strong ammonia , and strong smell of sweaty feet. Just finished an earlier pouch which was ok. Been using this product for yrs never a problem. Obviously some sort of contamination. Goes Well With:Bin

Poor packaging!
The product is ok, however, the pouche it comes in does not reseal, so I have had to empty the contents into my own container - to maintain freshness. The pouches they use have always been difficult to reseal, in my experience. Annoying! Goes Well With:Another container.

Setting the record straight
Okay here it goes, this is to all the bad reviews of this product..... I would like to point out that stupidity is not an excuse and if you want to slate a product do some research! 1. The reason it doesn’t mix well is because baca’s are non water soluble which means they will not dissolve in water, so the worse they mix the higher the quality!! 2. Most branch chain amino acids taste like ear wax end of get over it!!!!! And if your taking a product that mixes well and tastes amazing well done you’ve brought rubbish bcaa’s Covered in sugar

Very effective
Most of the time, I have a problem when consuming protein powders (my stomach just tends not to agree with it) and I steer toward consuming protein and other nutrients through food. I was advised by my personal coach to use this because I do quite a lot of weight lifting and L Leucine is very beneficial towards muscle recovery. I mixed this with some squash and I have to say that this gave me such a big energy boost during my workout. It really does help and depending on how much you put in your liquid, you hardly to cannot taste it. I put about 6g in about 500ml of water with 150ml of squash and there was an ever so slightly metallic/unusual taste but I hardly noticed it.Goes Well With:Fruit juice, Squash

Essential Amino Acid
L Leucine is an essential Amino Acid. Its main function is to aid recovery and build muscle after strenuous exercise. I use it for recovery protein drinks after long cycling rides. Since I started using it on a regular basis I have found a big improvement in my recovery window. Out of all the Amino Acids required to form good quality protein, L Leucine is probably the most important for athletes to take. So if you do take protein it is a good idea to supliment it with additional L Leucine.Goes Well With:L Leicine on its own doesn't taste too good so I mix it with MYPROTEIN Impact Whey Protein powder mixed in a shaker with a little honey. I sometimes add a little fruit like Bleuberries or Banana.

the must have supp
This is the must have supplement! Take 3-3g before and after workout with the basic supps (BCAA, Glutamin, Beta-alanin and whey, etc) and your goals are fullfilled. And let me tell you the secret about mixability: like all BCAAs mix it in warm (~body temperature) water (or tea)!Goes Well With:Everything
