Well today was the first day on TRT. I was given 200mg of Test Cyp by my doctor. He will be administering 200mg every 10 days. He mixes it with Vitamin B12. They do not give any HCg or anything for gyno prevention. He says it is not needed with 200mg e10d,s So does this sound right? I also wonder about roller coaster affect since it is every ten days. So I feel better already my question is should I try to find a estrogen blocker on my own and can I gain muscle mass on this program? I am 45 years old and have been lifting on and off all y life but have been lifting steadily now for last year.
