In the past I've done cycles without arimidex (nolva only) and encountered testicular shrinkage unless hcg was used periodically throughout the
cycle(s). I never do AAS without the use of arimidex anymore and have found that my "guys" never atrophy, even without the use of hcg. Does this stand true for everyone else out there? I'm wondering if there is a requirement for hcg if testicular atrophy doesn't occur? Thanks y'all.
