This is the third time that I've ran the product solo. I've never had any problem before. It wasn't for post cycle therapy or anything. About two days after I finished the bottle I noticed my right pec flaring up. I've had the problem a few times before on cycles and zapped it with nolva. I ordered some nolva and got to start taking it about 1 1/2 weeks after I noticed the gyno. I've been taking 80mg Nolva ED for 5 days and I haven't noticed any change in the size of the lump or the puffyness. Any other suggestions? I've tried Letro on gyno before and it never worked, nolva has been the only thing that has ever helped, but this time it doesn't seem to be working.
