Is your goal to build serious muscle mass? Looking to make drastic gains in strength and power? How does burning fat while you build lean, dense muscle sound? Outstanding, right? Introducing Andromass by Phase 1 Nutrition!
The Andromass supplement is a combination of two potently dosed and clinically proven ingredients that will turn your body into a muscle building powerhouse! Up first is 3b-hydroxy-5a-androstan-17-one, or Epiandrosterone (also commonly known as Epi-Andro). This powerful compound is extremely effective at building lean muscle mass and strength, all without having to worry about side effects that can come along with aggressive supplementation cycles. 
Because of it’s anabolic properties, you can use Epi Andro for both bulking and cutting. During a bulk, you can expect it to help you with putting on a good amount of size. It’ll also help with improving strength and overall performance. Especially when you are in a caloric surplus, this compound can be an excellent addition. When you’re trying to get lean this compound can also be extremely beneficial. This is mainly because it also has the ability to help preserve muscle when you’re in a caloric deficit. It will also produce a muscle hardening effect, as well as increase vascularity giving you a lean, dry, ripped physique!
Next, we have Androsta-3, 5-diene-7, 17-dione, or Arimistane: a potent and powerful aromatase inhibitor that keeps your estrogen level in check and subsequently boosts testosterone. This is important in bodybuilding because increased levels of testosterone help you not only burn excess body fat but also gain strength and develop muscles. Arimistane is known to be a completely naturally occurring substance. It simply works on balancing your levels of the two most important hormones in your body, the one known as male, and the other known as a female hormone. This leads to an increase in your energy and more efficient workouts.
