Extreme BCA-311 are branched chain amino acids (BCAA's) are an important tool for any athlete who is either looking to build new muscle or preserve existing muscle by preventing your body from going catabolic during a dieting phase for example or by being involved in prolonged high intense sports like triathlon, rugby, Cross Fit, MMA and bodybuilding.

BCAA's cannot be produced within the human body and MUST be sourced from your diet/supplementation. Nine amino acids are classed as essential because they MUST be consumed from our diet; the other 13 can be manufactured by the body. All three Branched Chain Amino Acid’s (BCAA’s) are classed as essential.

Extreme BCA-311 has an anabolic effect on protein metabolism by increasing protein synthesis and decreasing the rate of degradation in resting human muscle tissue. This makes them important to anyone looking to add or even maintain muscle tissue and those who suffer from post exercise muscle ache due to the benefits of enhanced recovery offered by BCAA’s.

Branched chain amino acids make up 1/3 skeletal muscle tissue and play such a crucial role in protein synthesis they are used clinically to help heal the injuries of burn victims. It has also been demonstrated that supplementing BCAA with carbohydrates immediately following exercise vastly increases insulin output. When combined with the body’s post workout nutrient requirements this increases protein absorption.

In studies BCAA supplementation has been linked with better immune system function. BCAA’s may also offset serotonin production, this promotes alertness and mental focus due to serotonin causing a feeling of relaxation and sleepiness, so not only will Extreme BCA-311 increase protein synthesis they may enhance your focus too.

Excellent value
I normally pop a handful of these on an empty stomach before cardio, or before a work out. Ideal for the low carb dieter and those looking to preserve lean muscle tissue in addition to other supplements.

I think that capsules are a lot more convenient than powders - I take 4 in the morning, 3 before training and 3 after training - I can definitely feel an increase in my strength when my diet is supplemented with these. Don't miss out on those important gains! Get some BCA's

Should i take extreme aminos along with my protein shakes?
You don't need to take them with shakes, but they are worth taking between meals to keep you in a positive nitrogen balance (anabolic).

Is it ok to take these at the same time as taking extreme trib-z and reload?
Yes, they will work well alongside each other and will not clash. Trib-Z and RELOAD are both natural test boosters, increased testosterone will bring greater results if protein intake is increased too and BCA-311 will assist with protein absorption so they will complement each other.

I am lactose and gluten intolerant, can i still use them?
Yes, they have no allergenic ingredients whatsoever.
