Been taking this for over 2 weeks now. I didn't feel any different and my sleep did not improve at all even with 6mg of melatonin. Testo booster doesn't work either. Instead, take Muscle Pharm Amino 1 for better recovery results.

This is an amazing product! Guaranteed deep sleep. Brilliant when doing heavy training to help the body rest and recover.

I've been taking z-core for a year now and its made a big difference to my sleeping pattern without relying on it to sleep. I much prefer it to a regular zma product

I was shopping around for a testosterone product suitable for female consumption and z-core did not disappoint! Sidenote: I do have hypothyroidism but so far no side effects, also i did notice faster muscle definitions and yes I do sleep a little better. Might not work for everyone but it sure does work for me.
