RPN Havoc represents the latest in a long, distinguished line of hormonal products designed to optimize the body's ability to maximize muscular hypertrophy. With an overall Q-ration of 12, Havoc is completely non-estrogenic and offers an ideal composition to maximize strength and lean mass gains with minimal side effects such as lethargy or gyno. Havoc is the peak of performance...period! Remember the popular pro-hormones in the past? Love to have something as strong or stronger than those products like 1-AD, Halodrol-50, PheraPlex? Havoc is the next generation hormone to deliver the amazing results: lean, dry, hard, quality chiseled gains, and without the unwanted and undesirable side effects from the old school hormones of yesterday such as acne, hair loss, etc. Havoc's active ingredient, 2a,3a-epithio-17a-methyl-5a-androstan-17b-ol, is an analog of an aromatase inhibitor used safely in Japan for decades. Independent studies have shown that Havoc is not only 15 times more myotrophic than Halodrol-50 and 20x more myotrophic than ProMagnon, but has an incredible myotrophic ratio of 12, whereas Halodrol-50 has a myotrophic ratio of 2.6 and Pro-Magnon a ratio of only 1.1.
