funny thing is i dont seem to need any ai's lately. my last blast i may have used a total of 2mg of adex and 100mg of nolva during trt and i havent used anything yet for this 1 at about 13 days in. i think the no ester in some way helps to prevent conversion to estro and i also think that injecting 30mg of estriodol with every 300mg of suspension keeps the balance right so the body doesnt have the need to convert the test but maybe thats just for me i dont know. people usually freak when i mention that i do that. i wonder how many if any have tried it and actually had a same or worst estro problem as they do without the estriodol.
