Tribex use with prohormones

Guys, i have a question: if using prohormones at the age of 21, is it beneficial to use Tribex during the two weeks (Androsol) to keep the nads from shutting down or just use for two weeks after the cycle - or both?? Thanks in advance for any adivce i get…

What I am doing is using 4 AD without Tribex/Vitexor M for one week. The second week I add Tribex/Vitex or M. The third and fourth week I take only Tribex/Vitex or M. The next week I take the 4 AD and drop the Tribex/Vitex or M and am going to use that cycle for a while until I am ready to go on a bulking phase.
