psychedout, I get asked that alot. When I used to cycle, they strank, would get big again, shrink again on and on...
Now that I stay on, they have returned to normal size and basically stay there. No problems with load volume either. Actually in January a fuck buddy of mine actually commented on me having a large amount of volume sometimes. I do notice that if I dramatically increase my dose quickly, like go from 75 mg to 125 mg overnight, or stack in tren or winstrol at 50 mg ed that they shrink again for up to a week before returning to normal.
I've talked with other guys who stay on year round and found that they seem to have the same effect.
No I've never used HCG. I've seen it in friend's medicine cabinets, but have never actually used it. When I cycled, I used clomid and nolva post cycle, and generally had my test levels around 800 ng/dL within 4 weeks.
