I don't know much about Anadrol, but that is a legit package probably got the image off of the British Dragon website, and from what I know they are a pretty reliable source and have good stuff. 20-30 lbs probably at the point of heaviest weight while using the drug, but you can use other things to keep off this excess water bloat.

I BELIEVE Tamoxifen would help keep off some of the excess water bloat but of course do your research and don't quote me on this one.

If this is your first cycle I would just recommend a test instead of jumping into other things (anadrol) and before you do anything make sure you have pct outlined properly and you have your pct gear before you start, just to be on the safe side of things
