Believe what they say. They speak the truth. I had 10cc of Sust on my first cycle and was very pissed off in the 5th week because that's when it kicked in.
You are just going to start to feel the Sust in the 4 week and you will be saying to yourself I wish I had more of this shit.
I know it's hard, not to start your cycle right now with those pretty little ampules in your hand, waiting to be broken at the top to suck that sweet ass nectar out.
Get you 20cc's for 10 weeks if you are going to do it or 24cc's for 12 weeks. You will be happier.
