puffy nipples , the itch like feeling in that area and basically fatty buildup in your lower pecs might be a sign of it.
what to do if you're getting it, drop the prohormones and cut your alcohol consumption to 0% until you have lowered your bodyfat % considerably then work your pecs to shreds especially your upper pecs, avoid lower pec work like decline presses at this stage.
Do this until the pecs regain their manly shape.
But if gyno is at a pronounced stage then I suppose all you can do is join the bitch club and do a bit of crossdressing!
sorry only taking the piss!
surgery would be your only alternative if gyno is at a pronounced stage of development.
Oh I forgot to mention that pot smokers have the highest incidence of gyno along with heavy drinkers and steroid/hormone users.
the standard price for surgery is approx$3000 and it has its risks.
still reducing your Bodyfat % to 7-10% or thereabouts is a recommended precaution and potential remedy to gyno in its early stages.
