I do not know what the domestic price of Korean Prop is. Supply and Demand will determine what a good price for you may be. I get it dirt cheap...absolutely dirt cheap...
1cc in the glute will be no big deal. 2-3cc's is another story. You'll be fine at work. If you're injecting in the quad, it will sting a little more. Everybody's different of course, but I experience more pain from winny injections than prop. I've used prop twice and believe me it's worth any pain you may feel tomorrow. Good Luck.
