For me:
Pro's: Increased weight from 252 - 262 in three full weeks time with a low dosage of 10/10/20.
Con's: Torn left pectoralis, bad lower back pain (feels like getting kicked in the balls, only higher)..
Lots of people report torn muscles/tendons while on these types of designer steroids. In all my recent research, it looks like you'll have a healthier time using the injectables. I've just finished reading one person's ordeal with their lipid levels and liver getting destroyed...
http://forums.bulknutrition.com/?showtopic=27951 When I torn my pec, I wasn't lifting anywhere close to my 1 RM..I was doing sets of 5 reps (no failure) with 345 lbs. In nine years lifting in the mid three hundreds for most of that time, I've never had anything like this happen.
After reading through your journal, I don't believe you need it yet since you most likely haven't ventured anywhere close to your potential naturally...When your journal starts to look like mine, you'll be ready grasshopper.
