ZMA & Saw Palmetto?

Do these 2 supplements have any negative effects when taken together?

Im taking ZMA before bedtime for its sleep/anabolic qualities and will be taking Saw Palmetto to help block DHT. Anyone tried this? Ive heard mixed reports on the Palmetto such as it doesnt hinder testosterone levels it just stops DHT and others who even say it lowers T levels too much to build muscle… (!?)

…any help appreciated!

Been taking both for just over a year now. Managed to bulk up pretty nicely.

I’ll be interested in seeing those reports that claim saw palmetto lower T-levels though.
