Recreational or Professional

It matters not whether you are a recreational or top-flight athlete, nutrition is still important to promote recovery from exercise, to minimise injury risk and to replenish your body after exercise. XL Synthesis contains nutrients that can do all these things.

Why is XL Synthesis so good?

One of the claims of XL Synthesis is that the carbohydrate source (Waxy Maize Starch) will not cause bloating as other products do. This is a very tangible benefit and the fantastic advantage here is that all you need to do is try the product to test this claim.  After using XL Synthesis you will feel ready to eat again within around 60-90minutes, a time period that most top nutritionist would have you eat in after consuming a post-workout shake. You may even find you are more hungry than after using other products due to the rapidly absorbed ingredients being taken up and used for the recovery process.

The protein source in XL Synthesis is hydrolysed whey protein (HWP). This is the most expensive and highest quality of all the whey proteins. HWP is broken down and absorbed much quicker than whey protein concentrate or isolate and therefore gives a quicker and greater spike of amino acids in the blood stream, ready for muscle growth and repair. This is also further enhanced with the inclusion of L-Leucine, an amino acid which has been shown to activate growth and repair of muscle tissue.

Some people have asked why Excel Labs have not added a large amount of the branch chain amino acids (BCAAs) to XL Synthesis. The answers is that with the use of the Hydrolysed Whey protein and Leucine there is both no need to add BCAAs as well as there being a detriment to the formula. With the whole ethos of XL Synthesis being on fast delivery of nutrients, having BCAAs in the formula would further increase the osmolality of your shake which would mean it would take longer to get from your stomach to your intestine where it can be absorbed.
