I don't know if the gains will last, but in 1 week and 1 day (this morning), I was 12 pounds up. I'm using the Finasol method ... I wish I'd not wasted my time with all the androsol / nandrosol stuff but live and learn I guess. I also didn't anticipate the nip issues, otherwise I would have waited until I'd secured something to combat it ... but I don't feel any hard mass forming, just puffy on the left side. I've read at least one other post about nip sensitivity while using fina.
