Take it at night, it does work

Posted by Reviewer1413779 on Jan 27, 2016

I've taken many test boosters, this is the most consistent. I take it at night before bed. It does work, mine kicks in around 7 days others may be different. It's an excellent ZMA, with extra ingredients also to help boost test.

Been taking it for two weeks and haven't notice anything. Going to finish the bottle just because I got it.

not as good as testo jack 200 was for me

Posted by 5189986367392137070 on Jan 04, 2014

I tried test Jack 200 a long time ago and it seems to work really good but it was just kind of expensive at the time to repurchase.so I bought the test jack 100 this time and it doesn't work as fast . I think if you buy jack 200 you're going to be better off IMO.
