Bigdex28,
The main things I used are Pge1,Igf-1,igf-lr3,mgf,hgh,DHT and probably other things that I cant remember.
On the days I was injecting pge-1 I had a couple of hours erection followed by another couple hours of lower erection , so basicly you can't do a lot of exercises with a erection.When the erection reduced enough I was doing the exercises that you can find on this site.
Also if you want my advice go do your own research as their are people on the internet who use pge-1 the wrong way and they litteraly fucked up their penis and need 100 time the average dose to get erect.Also Don't inject each day ( Its to bad and one of the reasons why it doesnt work very well) because it will lead that your penis tissue( pge1 receptors) become very insensitive to pge-1.Also injecting each day ( forget about injecting couple times a day) there is a bigger chance of getting a priapism, most likely because the next dose is cumulative.
Good luck.
