A good oral is Turinabol, like a dry Dbol or a juicy Anavar if you want a different analogy - created by those clever East Germans purely for performance (no medical usage as far as I know) and a nice compromise between estrogenic orals like Dbol & Adrol but stronger than Avar and Winnie....very popular in the UK currently.
You’re going to plateau after a while, that’s why cycles have a duration (10 weeks, 12 weeks, 16 weeks etc) - you’re supposed to come off/PCT get blood done and go back on when everything returns to normal...unless you plan to cruise on TRT doses between cycles?
Don’t up the dose, 750mg/week is plenty - try micro dosing instead, lots of top guys in Europe have abandoned the once or twice weekly Test shot in favour of daily injections instead (less scar tissue, better uptake, fewer sides, stable blood levels, better utilisation etc), guys who were using 500-750/week are now getting better results on 50mg/day (350/week) -
Give it a go.
