  • PROMASIL, our elite multi-source protein blend.
  • STEAM BCAA, our intra-workout amino.
  • ENPULSE, our herbal hormone support.
  • 2 RIVALUS Beanies, one for you and one for your sweetheart.


Proteins come in a variety of forms. Sources like whey are ideal around workouts when you want aminos - fast. Casein proteins are better between meals and before bed when slower delivery, over several hours, is preferred. Moderate-release proteins like egg and goat's milk are easily digested and contain all of the essential amino acids, which makes them great choices most other times. PROMASIL's elite blend combines fast, intermediate, and slower-digesting sources to deliver the best of all worlds: a single protein powder that is versatile enough for all day use. Whether you drink your shake in the morning, after workouts, or between meals, PROMASIL's multi-source blend provides broad-spectrum amino acid coverage in one convenient package.

About one third of skeletal muscle – the type that flexes and gets stronger when you exercise – is made up of branched-chain amino acids (BCAAs). So it shouldn’t be that surprising to learn that athlete’s requirements for leucine, isoleucine, and valine are higher, or that supplementing with these key aminos has been scientifically demonstrated to improve performance.*


STEAM BCAA helps you train longer and supports recovery with a kick-in-the-glutes combination of BCAAs (popular 2:1:1 ratio), plus added glutamine, citrulline, electrolytes, and vitamin B6. No banned substances or added sugar simply ensures training harder is also training smarter. Never run out of STEAM. *

In the quest to build bigger, more powerful muscles, many athletes seek supplemental assistance to modulate hormone levels. The goals being to safely and naturally elevate anabolic varieties that are considered beneficial for muscle building while reducing levels of others that may counteract these effects. * Formulated with extracts of eurycoma, tribulus terrestris, avena sativa, milk thistle, and maca, ENPULSE™ is designed gradually support the body’s natural anabolic processes without the use of prohormones or other illicit or banned ingredients that athletes – especially those who compete – would be wise to avoid. *

Add 1 scoop of PROMASIL™ to a glass or shaker cup filled with 6-8 ounces of cold water. Stir or shake for a few seconds until powder is fully dissolved. Enjoy. Tip: For an added treat and extra nutrients to assist with recovery, try blending PROMASIL™ with ice cubes, milk (cow’s, almond, cashew, etc.), fresh fruit (bananas and berries work well), peanut butter or peanut butter powders, and/or spices and extracts (e.g., cinnamon, nutmeg, extracts of vanilla or peppermint). Check our Recipes section for more ideas.
