Think of it like this; If you were to come off a cycle and your nuts were atrophied, how much harder do you think it would be to get them functioning? They have been dormant, and not functioning due to lack of LH signaling. So you would take your clomid or nolva after cycle with atrophied testes, giving the HP axis proper stimulation to begin LH production. But if your nuts have been shut down and not used to getting the signal (LH), they will take somewhat longer to restart in the overall recovery process. However, if you were to keep them functionally receptive to LH by providing HCG during cycle ( ex,whether you do 2 weeks mid cycle at 500-1000 IU/week or do 500-1000 IU weekends only throughout cycle, this is always controversial) they will never atrophy in the first place. So when you come off cycle, wouldn't it seem like your testes would be more receptive to clomid/nolva in recovery? Just a thought
