How long can you take it before you should stop?
Provided you follow the cycling instructions on the label (5 days on/2 days off), you can use Alpha Male indefinitely.
It’s still not a bad idea to consider a week or two off after 12 or so weeks. But, as per the label, you’ll want to use it for at least four weeks to attain full effects.
Do you need to take Rez-V when taking Alpha Male?
