Very effective estrogen blocker
Z--Test is one of the best estrogen/cortisol blockers I have ever used. I always get my estrogen levels checked before and after I run any product like this, and Z-test was one of the only ones to actually lower my estradiol levels 22 pts, down to 25pg/ml - which is a great place to be post cycle. Very impressive. Z-Test did exactly what it claimed to do and more- I enjoyed running it, and will definitely be using it again for my next cycle.
