My best friend, everyone says that when its really the OP, but it really is. He's overweight about 6"1" and 343 lbs. His doc put him on test replacement due to being rather low, 378. He just had another test done and his numbers are now at 780 at 1cc per week of test cyp 250mg/cc, which seems low to me. I've seen lab results where guys have been in the 1000s at 1cc per week from the same vendor. I know the oil is good, I use it also and always get great results, as do other guys I know that also use it. My question is, will high estrogen levels drop the test levels or just make the test less effective? His estro numbers are 50 and high acceptable levels are 44. I know high estro levels will destroy natural test levels but will they bring injectable test levels down too?
