For seasoned muscle enthusiasts, this product complements your highly developed stamina and strength, allowing you to burst through plateaus and shake up workouts with new, more grueling strategies, such as pyramiding, drop sets and negative reps.
What’s in SizeOn Maximum Performance?
A proprietary SizeOn Blend is the workhorse complex of ingredients that Sizeon Maximum Performance contains. This blend is essentially creatine, carbs and protein. The foundation for this blend is a decent array of vitamins and minerals, such as vitamin C, five vitamins from B-complex, calcium, magnesium, phosphorus and sodium.
The C and B vitamins help your body to manage the “stress” that lifting places on your body, boosting your immune system, nervous system, circulation and energy production. Vitamin C is also a powerful antioxidant, neutralizing free radicals and the damage they cause.
The four minerals in this product provide some electrolyte support, enabling muscle contractions and mental clarity while minimizing the risk of cramps.
The remainder of the ingredients in this product make up the SizeOn Blend, which amounts to 63 grams of compounds and nutrients. The blend consists of two matrices and two complexes.
Carbohydrate Energy Matrix
This matrix includes several sugars, such as dextrose and trehalose. Dextrose is a form of glucose, one of the simplest, basic sugars that your body utilizes immediately after it enters your bloodstream.
Trehalose, naturally present in foods like shrimp, mushrooms and lobsters, is another simple sugar consisting of two small glucose molecules. Although trehalose is a simple sugar, it is a slow-digest carb. Trehalase, the enzyme required to break down trehalose, exists in the human body, but it works very slowly on trehalose.
Consequently, trehalose takes longer to impact blood sugar, supplying a steadier and more gradual stream of simple energy during your workout. This keeps your energy at an even keel and prevents the dreaded experience of crashing.
Protein Synthesis Acceleration Matrix
Whey protein hydrolysate and the BCAAs l-leucine, l-isoleucine and l-valine constitute this matrix. Recall that BCAAs are essential amino acids, which means you’re body requires them but can only obtain them from external sources. In your body, BCAAs stimulate the synthesis of new protein (muscle).
The combination of BCAAs and whey protein furnish your body with the necessary tools to promptly begin rebuilding the muscle you’re breaking down so as to maximize your gains. This matrix also ensures that your body does not enter a catabolic state, which is always a danger during hardcore lifting.
Catabolism is the breakdown of muscle for energy, a regrettable outcome of working out for extended periods at high intensity without sufficient carb energy in your blood, muscle glycogen and or available protein.
PhosphoDrive Endurance Complex
This complex features an assortment of creatine supplements, such as creatine monohydrate as Creapure, magnesium creatine chelate as Creatine MagnaPower, and disodium creatine phosphate.
Each form of creatine offers the same benefit to your body. Creatine is the basic energy your body uses for muscle contraction. Creatine also ushers extra water (electrolytes) into your muscles, giving them a fuller, more beefy look.
Creapure and Creatine MagnaPower are trademark forms of creatine by AlzChem and Albion Human Nutrition respectively. Both are highly respected manufacturers of sports nutrition ingredients in the business-to-business sports nutrition market. Creapure is micronized, while Creatine MagnaPower is creatine and chelated magnesium.
Each has superior loading affects, saturating muscle with creatine more efficiently and quickly.
Osmodrive Advanced Hydration Complex
This complex helps your body to replenish, rehydrate and recover. A mixture of glutamine, taurine, magnesium, calcium and potassium, this complex flushes lactic acid out of sore muscle and stimulates the rebuilding of muscle and tissue. It helps you to bounce back more swiftly between workouts, to workout more often and improve the rate at which you gain lean mass.
Clinical research and studies confirm the efficacy of the high quality ingredients in SizeOn Maximum Performance. As with any supplement, consistent dosing over a period yields the most noticeable results. Depending on genetics, diet, level of experience and your workout regimen, your results while using SizeOn Maximum Performance might different from some other guy’s results.
