MPA Muscle Intrusion

It is time to rethink your intra-workout nutrition with the arrival of LA Heavyweight Champion & Europa Super Show Overall Winner Matt Porter’s cutting-edge supplement, Muscle Intrusion! Muscle Intrusion is the first product to be released as part of the new Matt Porter Approved label, providing only the highest quality ingredients for unmatched recovery and results.*

Induce the state of Hyperemia‘ with MPA Muscle Intrusion!

MPA Muscle Intrusion is a precisely-formulated ‘Intra-Workout’ drink that is intended to be consumed throughout your intense weight training session or endurance exercise. Each ingredient is readily absorbed into the bloodstream, minimizing gastrointestinal distress throughout the digestive process. The synergistic effects of the powerful new ingredients Highly Branched Cyclic Dextrin and Agmatine Sulfate work in conjunction with Matt’s signature essential amino acid complex to offer the potential to significantly increase blood flow, improve Mtor signaling, lower cortisol levels, replenish glucose and glycogen levels, and provide unrivaled nitric oxide-induced muscular pumps while helping to keep you hydrated.*

Just how exactly is this achieved? Let’s take a closer look at the active ingredients in this ground-breaking formula for the answer.

Highly Branched Cyclic Dextrin is the engine that drives all other ingredients into the bloodstream. Highly Branched Cyclic Dextrin is derived through the enzymatic breakdown of amylopectin into smaller clusters, which are then reassembled into large cyclic chains using a branching enzyme. This process forms a unique carbohydrate material with a higher molecular weight profile and lower osmolarity than most other dextrins, as suggested in separate studies conducted by Hiroki (et al.)1 and Takii (et al.)2. Their claim is that the Highly Branched Cyclic Dextrin may exert an amount of osmotic pressure that is lower than that of the blood and other bodily fluids, creating a hypotonic environment which allows the material to bypass the stomach and enter the small intestine at a much more rapid rate as compared to other carbohydrate sources1,2.

A previous study presented in the Scandinavian Journal of Gastroenterology serves as additional support to the claim, suggesting that materials possessing a lower osmolarity may allow for an increase in gastric emptying times3.. A more recent study shows a strong correlation between the rate of glycogen replenishment in muscles while using carbohydrates with a high molecular weight and low osmolarity before exercise as opposed to carbohydrates with a low molecular weight and high osmolarity4.

The intended result is to increase the absorption rate of energy-producing carbohydrates, as well as reduce the transportation times of vital fluids and electrolytes that are essential to your strength and recovery.* Highly Branched Cyclic Dextrin demonstrates the potential to replenish energy levels at speeds that may surpass those of other industry-standard carbohydrates, including dextrose, maltodextrin, and waxy maize starch following intense exercise.* Rapid gastric emptying may also help to reduce the cramping and bloating effects that are often experienced with other carbohydrate sources.*

When it comes to increasing blood flow and the production of nitric oxide, nothing can compare to the effects of Agmatine.* Agmatine is derived from arginine using a chemical reaction that eliminates the carboxylic acid end from the molecule5. The resulting structure serves to regulate the production of nitric oxide synthase (NOS), which then influences the amount of nitric oxide that is released into the bloodstream6. Increased blood flow, in turn, creates an increase in the amount of vital nutrients and oxygen that can be supplied to the muscles, which is a key component in healthy exercise7. This has led many to label agmatine as a form of “Super Arginine.”*

Studies suggest that agmatine may also be responsible for the production and release of several peptide hormones, including the growth hormone (GH), luteinizing hormone (LH), and pituitary hormone6. As a neurotransmitter, agmatine is released through the process of membrane depolarization to block NMDA receptors and other cation ligand-gated channels7. This poses the potential for increased learning and memory functions7.

With Highly Branched Cyclic Dextrin providing the method transportation for the uptake of vital nutrients, muscle cells are rapidly replenished with the energy and aminos that are needed most for proper muscle metabolism.* Each serving of Muscle Intrusion comes packed with a complete essential amino acid complex that has been specifically-designed to prevent a fight for absorption and to fuel muscle cells with the exact combination of ingredients that are needed for growth.* In addition, Matt has included L-Glutamine to restore depleted levels in the bloodstream following intense exercise, and Creatine Gluconate to help restore ATP and transport energy to the mitochondria and myofibrillar cross-bridges in order to generate increase muscular contractile force8.*

It is essential to remain properly hydrated while undergoing extensive exercise in conjunction with the use of this product, which is why Matt has also been sure to include added electrolytes to aid in the flow of liquids throughout the body. This not only helps to prevent cramping, but will fight the effects of dizziness, fatigue, muscle spasms, severe dehydration, and abnormal heart rate while you work to increase your endurance and efficiency in the gym.* Matt recommends that no less than 48-64floz of water be consumed during use to maintain proper hydration, experience maximum cellular swelling, and to increase overall digestion of the materials.*

MPA Muscle Intrusion (30 Servings)

Directions: As a dietary supplement, a recommended 1-3 servings (1-3 scoops depending on individual requirements) of Muscle Intrusion may be mixed into 48-64floz of water to SIP between sets, or during periods of intense endurance exercise. NOTE: It is important to ensure adequate amounts of water are added to the formula to dilute the ingredients and allow for better digestion and assimilation of ingredients while providing the proper hydration to muscle cells. 48-64floz of water is recommended.
