I just started my first ever cycle of test. I have a couple questions I hope you all can answer for me. First question I took my first 1 cc shot of sus yesterday. I'm going to do 2 cc's a week (500 mgs). how long before I start noticing a change in my body, libido, ect (how do I know it's working)? Secondly I used an 18 gauge pin in my quad and today someone told me that was way to big. Does it really matter if I don't notice any major pain or discomfort, or do I need to buy some new sticks?
