If they are not growing I'd take enough AI to keep it like that and worry about shrinking them when off cycle. If you try to do while on you will inhib gains and so waste the gear you are on. Take as much anti prolactin ad you want as low prolactin won't inhibit gains like crashed or very low e2 would.

letro man, it is the strongest AI.....chemical need will have it. go 2mg ED for 10 days, than 1mg for 10 days, than .5mg for 10 days. hopefully that blast will shrink it, and get rid of it. add the prami if you want your dick to work while on the letro.
than switch over to a lighter OTC ai like forma stanzol. (formestane)
