The half life of hCG really wants dosing every other day.
250-300iu SC EOD is a replacement for natural levels of LH.
For that to work, your testes need to be in good condition.
Low dose hCG typically does not cause any problems with high T-->E2 inside the testes. I have seem that in one or two guys here. Nothing recent for a long time.
hCG does not travel well or easily. You could use Nolvadex when traveling if traveling is a problem.
If you have lower T levels, E2 management may be more critical, considering T:E2 ratio.
