Labrada Nutrition A2-Pump Overall Review: 3 out of 5.

A2-Pump by Labrada Nutrition is made of one hundred percent Arginine Ethyl Ester HCl. Each serving offers a 1590mg dose of this esterified form of arginine that is designed to penetrate the plasma membranes of muscle cells and increase nitric oxide production. A2-Pump claims it can increase muscle pumps, escalate vascularity, and improve muscle hardness and definition – and do all this in just days. Arginine is a semi-essential amino acid and is a precursor to nitric oxide, which is a blood vessel-widening agent (or vasodilator). It may also trigger the body to make protein. Your body may have all the arginine it needs, so supplementing may not be effective for you.

Taking arginine supplements may cause side effects or allergic reactions. Some of these include bloating, diarrhea, nausea, and stomach pain. It also may increase the risk of bleeding and may affect blood sugar levels. It is important that when taking this supplement you talk to your doctor to make sure it won’t interfere with any medications or medical conditions.

One serving is 3 capsules and each container has forty servings. It is recommended to take two servings worth each day. On training days, take one serving with 12 oz of water twenty minutes before working out, and take one serving thirty minutes after workout. On non-training days, take one serving in the morning and the other serving in the afternoon/evening on an empty stomach – or with a meal.
