What are the Main Benefits of this product?

XL Synthesis is the ultimate post workout supplement. As recovery serves as one of the most important factors in growth, it is essential that in the post exercise window, the body is supplied with all the nutrients it needs, rapidly. XL Synthesis contains 4 key products designed to aid this process. Firstly Waxy Maize Starch, a rapidly absorption carbohydrate that does not cause bloating and because of its high molecular weight [1], causes other nutrients contained in XL Synthesis to be absorbed quicker.

Secondly Whey Protein Hydrolysate (WPH), a pre-digested form of whey protein. As it is pre-digested it is absorbed and assimilated quicker by the body [2, 3]

Thirdly the amino acid L-Leucine, shown to independently stimulate protein synthesis (anabolic) pathways, thus causing a direct increase in protein synthesis post ingestion. [4, 5, 6]

Finally the worlds most researched and used ergogenic acid, creatine monohydrate. Creatine acts as temporal and spatial buffer of ATP, our bodies primary energy source. Many years ago it was found that creatine monohydrate helped to raise muscle phosophocreatine [7] and a plethora of studies have shown it to improve exercise performance [8]

What are the ingredients?

Waxy Maize Starch (Amylopectin), Hydrolyzed Whey Protein, L-Leucine, Creatine Monohydrate, Flavouring, Sucralose

How many servings are there per Tub?

Our Excel Whey+ comes in two sizes: 2KG and 960g. A serving sized is based on bodyweight to give an accurate amount of carbohydrate after exercise for maximal recovery. Please see the table below which will also give an indication of servings per tub

How long with the tub last?

The total time that the tub lasts will depend on how frequently you exercise and your bodyweight (to determine a serving size)

When should I take it?

XL Synthesis should be solely taken after exercise, after a match or during a half time interval.

And what with?

Only water, this will depend on amount used and taste preferance, however we recommend drinking water after ingestion to aid gastric emptying and absorption.

How does this Product taste?

XL Synthesis was designed in performance enhancing and recovery in mind, we took our selection of ingredient, formulated them and then flavoured them (not the opposite way which some companies do which reduce the effectiveness of the performance ingredients!). Due to this method, this product does not taste like a whey protein supplement or a very sweet sugary shake. However it does have some flavouring to mask the taste of the ingredients but this is not a nice flavoured and tasting drink, it is the ultimate post exercise recovery drink.

What other Excel Products work well with this?                       

A variety of other supplements work well with XL Synthesis. We recommend that users be taking XL Whey to ensure a high protein intake through the day. Synthesis can also be taken alongside XL Creatine to ensure that on offdays one can maintain their creatine intake (does not need to be taken on training days as XL Synthesis contains creatine)

Is this product safe?

This product is entirely safe with no shown adverse health effects. Due to the milk fractions used, those allergic to milk are advised to use caution when using this product Always read the label before use.
