First I posted a while back about knots under the skin w/ Ghrp injections. Its been over a week and the pain has gone away but the knot remains... how long will these solid masses be under my skin for? Second. I have gyno lumps under both my nipples which are solid and painful. How should I go about getting rid of these? Letro? If so how much and for how long... I want to be rid of these puffy nipples and the hard tissue underneath.
