Depends on what your expectations and goals are.
If you are a lard ass, you won't see much. (sorry)
If you are lean and only after pecs and abs for your next model shoot, you will be more than pleased with the results.
However it would be wiser to go 50mg for 10 weeks instead of a higher dose for a shorter time. I mean, muscle isn't going to magically appear in places that quickly and stick around when you discontinue.
Many people focus all their efforts on making gains from roids, but totally ignore the more important aspect of maintaining gains that were made and nuturing them until they are permanent lean muscle additions.
