Luke,
I'm not all that familiar with Taurus M1P but it's undoubtedly progestin based. I would highly recommend a good AI alongside this product. It's just good insurance against possible gyno sides. Althoough progestins don't convert directly to estrogen they have a history of causing gyno in addition to other potential issues. Typical progestin realated sides are gyno symptoms, libido loss and aggressive mood swings. Part of the reason gyno may be a problem with this compound is because it lacks androgenic potency and down-regulates DHT levels during cycle, which is the body’s natural estrogen blocker. However, users usually experience rapid gains in strength and aggression, followed by significant weight gain after several weeks. The results are generally fairly lean with only minor bloat due to the progestational effects.
