i started bodybuilding around mid august this year
and gained 10 lbs of muscle. my diet would be considered
Optimum nutrition 100% gold standard whey protein power
that is pretty much all i ate and NOTHING else
around mid september the gain leveled off and i noticed a hard lump under my right nipple and today its around grape size.
and its pretty bogus that this is happening and i pretty did it on the safe side. theres nothing on the left side.
the milk or protein are the only thing i suspect could be the cause of it
1) Do these products have secret hormones that the consumer does not know about?
2) How to do i stop this from growing?
