Great Product
One of the best products that I have consistently taken for over 5 years. No need to cycle off. Amazing quality of sleep, I usually sleep well anyhow, but with Ztest my quality of sleep is better and deeper sleep. Wake up feeling great and ready for my crossfit workout. I workout 5 days a week, and Ztest provides me with the recovery I need to start the day strong. Recommend taking it with test 600.

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.

How long can I use safely?
A shopper on Mar 17, 2017
BEST ANSWER: I take it the time. From what I researched and have been told, you don't need to cycle off Ztest. Although I always like to take a one or 2 weeks break from my supplements every three/four months and do a complete body cleanse/detox.
Why can't you take Ztest with dairy products?
A shopper on Feb 12, 2019
BEST ANSWER: The milk coats/puts a lining around the supplement making it less effective.
How many a day is required to take?
