Just did my first shot. It stung a little afterwards. Doing one 100 mg shot every MWF for the last 6 weeks of my sus. 500 mgs/wk cycle for 10 weeks. I have the clear primo amps with the white paper label on them. There is a blue dot right above the neck. The amps have air in them, so when you hold them upright, there is some in the neck. When you break off the top, you loose some. How do I counter this problem of the primo in the neck? I tried letting it sit upright for a while and tipping it a couple of times, it didn't work. Any suggestions???
