For a 1st cycle I'd recommend test.
Most sides can be avoided with reasonable doses and the proper ancillaries, but I think the answer you're looking for in anavar. 40mg/ed for 6-8 weeks.
Well, is this your first cycle???
For my first cycle I did 12 wks of 500mgs Sustanon (250mgs twice a wk, Sun and Wed)/ .50mls Deca Durabolin/ DBol 30 mgs x day, first 6 weeks of cycle (10mg morn, 10mg mid day, 10mg before bedtime. I put on 30lbs with this cycle and kept 20 at age 42
Good luck to ya.
