I'm on my third pin and am having second thoughts about taking Test-Sust. I'm 24 years old and been training for 8 years, never took anything and was gonna run a Sust only cycle. I have no sides yet and no shrinkage. I did get the Sust flu my first pin but honestly I was a little bit under the weather before my first pin. Although the workouts have been great and I gained 10lb of mostly muscle, I feel like this will be a decision that will cause me to be on and off for the rest of my life. I have an addictive personality, I already am feeling consumed by the slight gains I made, so I might be tempted to abuse it later on, or raise the dosage like many people in my gym. I also have a drug test coming up and they may test for steroid usage. I did three pins of test Sust at 250 each, is it safe to stop without a pct at this point or should I begin my pct?
