You will day in and day out be able to push yourself harder and longer than with any other intra-workout product on the market today. You will see greater results in less time, bringing you that much closer to attaining your goals. SUSTAIN is the best intra-workout supplement if your goal is to improve workout performance and build muscle.
- Enhance endurance and increase training volume
- Stimulate muscle protein synthesis
- Buffer acidic metabolites (i.e. lactic acid)
SUSTAIN is formulated with 25g of dextrose to provide the body with a quick source of calories to replenish cellular energy. Dextrose, chemically identical to glucose, is one of the quickest digesting carbohydrates and is an excellent source of energy. The body quickly converts glucose into glycogen, the stored form of glucose within the body. Glucose also triggers the body to release insulin, which in turn brings additional glucose and other nutrients into cells. In turn, consuming dextrose during your workout will allow the body to quickly replenish muscle glycogen. More glycogen means more reps, more sets, and better results. SUSTAIN also includes beta-alanine to buffer lactic acid to diminish the “burn” felt during your hardest sets.
SUSTAIN includes 7.5 of branched-chain amino acids, also known as BCAAs, to stimulate muscle protein synthesis. The BCAAs are part of the nine essential amino acids that cannot be synthesized by the body. It is very important to ensure ample BCAAs are consumed post-workout to prevent a deficiency that may prevent proper recovery. The BCAA leucine has shown particularly useful in preventing muscle protein breakdown and stimulating new muscle growth. Studies have shown that post-workout leucine ingestion stimulates mTOR activity thus leading to more muscle growth. SUSTAIN also includes a massive 10g dose of l-glutamine per serving. Glutamine is the most abundant amino acid within muscle. It also plays an important role in both intestinal health and the immune system. Although the body can synthesize glutamine on its own, strength and resistance training induce a demand for glutamine that the body cannot accommodate. Supplementing with glutamine while training ensures the body has an ample amount of this amino acid to fulfill its needs.

I got this with the preworkout. The taste is awesome and I’ve noticed recovery has improved. I do crossfit and normally I’m pretty worn out after workouts but since taking this I don’t feel as drained. I recommend this for anyone that does extended workouts.

I found this product being advertised on Instagram with a discount code. I used to mix BCAAs and carbs for my workout drink and liked that this product had that plus 10g of glutamine. The Blue Raspberry flavor is amazing. It’s the best version of that flavor that I’ve ever tried. I’ve noticed I don’t get tired as quickly while working out and I feel more hydrated.

I got a sample of this and their preworkout at a local gym. Blue raspberry tastes just like koolaid. I’ve been able to workout for longer than I could before taking this product. I can’t wait to try other flavors.

I was getting headaches after cardio and wanted a product that could help keep my blood sugar up and had BCAAs. I use 16oz of water over ice and I feel great when I’m done with my morning cardio. This brands version of blue raspberry is the best I’ve ever tried.

I can’t understate this enough, the blue raspberry flavor tastes amaaaaaaaazing. Over some ice it tastes just like koolaid. Definitely noticed I was able to get of few more reps out of each set and I didn’t feel completely drained at the end of my workout. Great bcaa product.
