Newbie On Sustanon

I just found out that a pal who’s never tried roids started a Sustanon 250 cycle almost 10 weeks ago. I’m still growing my knowledge on the matter, but it would seem that he should probably come off the cycle very soon.

As a novice, is a three weeks on, four weeks off regimen more advisable? Also, he only has the Sustanon. He does not have any other substance he can use to taper or kickstart his own body’s T-production when off-cycle. What would be recommended in this scenario and in a 3 week on, 4 week off scheme?

Thanks for any help.
