To be honest, you'll see much more gains in terms of strength and size with a 1 month cycle of somethign like SD, M1T, or Halodrol than you would on 3 months of say 500 mg of test enan per week (a beginner dosage). The orals do have sides that are a bit more harsh than the said amount of test. Just because these PH's were legal in the recent past, do not be fooled, they are just as potent (esp in terms of sides) as the tried and true compounds such as Dbol, anadrol, tbol, etc. I have a lot of gear experience and have tried everythign except M1T and I can honestly say the only AAS thats in a league of its own in trenbolone. Things like deca and DBol have their place for sure, as does test (I've never run a cycle to date without test) but pound for pound, you cant beat these new designer steroids. However, as said earlier, the sides can be NASTY.
Anyhow, ideally you'd want to stack test with something like SD or Halodrol, but we're getting ahead of ourselves. For a first cycle, knowing what i know, I'd go with test for 3 months, recover with a proper PCT, then depending on how i responded, assess my need for further cycles and what they should consist of.
Good luck.
