You plan A is what you should be doing. On the aromasin, I would start at 3x per week and see where you are after 6 weeks with bloods.
For PCT you will wait 3 weeks after your last shot before starting.
This is what ot it should look like.
50/50/25/25/12.5/12.5 This is daily dosing per week for 6 weeks.
Please start training log in the training logs section so we can follow progress and you can ask there is you need help. Tag me @s.gentz. That way all info will be in one thread.
