Whoa.
Curious, how big are you, like height weight and BF%?
You don't have to be huge to do chest, if that is what you are implying. I used to do them when I would use more short esters (basically tren ace as the more I put in one spot the more I possibly would cough, etc.) so needed pinning spots for the amount I was taking at the time and I am far from a mass monster. Always felt a bit weird to me even though they were pretty easy.
