Anavar is so damn expensive, its a bad idea to not do PCT, its like throwing away a bunch of money if you lose any gains. Besides, clomid and nolvadex are cheap as hell.
Since anavar only cycles are geared towards no side effects nolvadex would be your best pct choice. Clomid has a bunch of side effects which you'll want to avoid.
Nolvadex at 40mg/day for the first 10 days and then 20mg/day for the remaining 18-20 days. I saw great results from protein factory's unleashed and post-cycle. So I would throw those in too.
I gained about 5 pounds and I still weigh the same (It's been two months). I was able to do a set of 5 at the squat with 415 and I did a set of 8 with 395 last week.
IN my opinion, keeping the gains (especially for strength) is more a psychological thing than a hormonal thing. I fyou expect to have diminishing strength, that's what will happen, whether you use clomid or not.
