I was wondering why they used so much, also... but then I got to thinking...
They didn't state whether they used regular IGF-1 or the LR3 version... but I imagine they used the regular, because if they used the LR3 version it would be quite a bit considering what others have used (with good results) and the dramatically longer half life the LR3 has over the regular... I've talked with people taking as little as 20-50 mcg's of IGF-1 LR3 (including myself), that have gotten quite dramatic results (on muscle growth and joint rejuvenation, anyways)! If they did use the LR3 version (wich I doubt), they were giving the upper limit of doses recommended (150-200mcg) and that's been know to cause some nausious/dizziness feelings after injections unless you've worked your way up... I'm sure they would have mentioned that as a side effect.
I do know for sure that 30-50 mcg's a day of LR3 is enough to start out with, if you're interested in some muscle growth and joint rejuvenation (as well as decreased bodyfat, increased appetite and increased erections). I didn't measure my penis, so I don't know for sure if it grew from the 3 weeks I was on 30mcg's a day... but I did hang heavier durring the day and always woke up with a raging wood... as well as increased # of erections. I couldn't tell you if it will make your erections harder, because I seem to always have rock hard erection, like I just took a viagra I didn't even need (nananabubu). All kiddin aside...
In 2 weeks I'll start my last 3 week cycle and let you know if 50 mcg's a day was enough to make a difference in my Penis Enlargement gains.
Peace
