Taken on it's own I would think the likelihood is very low but could be a contibuting factor when combined with AAS. I would need to research further but sure I have read at some time that HGH can increase expression at the prolactin receptor so you couple this with a rise in estrogen from AAS use and you certainly increase the chances of gyno if not mitigating them with ancillaries to lower both estrogen and prolactin.
was just curious. Had sensititive nips for the first time in 3 years of heavy juicing but had some letro on hand and i'm good to go now. probably was the deca.
