I wont be running a log, but I have been using cel formestane. Luckily for me the first bottle of cel was running out so I jumped right in with forma.
Other than the minor pump issues this shit is awesome. I can feel the skin on my chest tightening very soon after applying, and it lasts for some time. This stuff is awesomein the 2 days Ive used it.
Gotta love stuff that you notice instant results from!
