It takes a while for me. I found it came on in a few weeks wioth tren, tehn went away when I used bromo or came off. Then, with test, it came back fast to the point it left off before but then slowed down. Now, while still on, I can still feel some small, painless lumps but you can't tell by looking. The lumps still appear to be getting smaller. T hey went away entirely the two times it came on from fina. I'm hoping it will go away again entirely after this cycle though I can live with the way they are now I suppose. Just get leaner and you can't tell at all.
