Very interesting. I have always hheard that you should be careful with air and veins. Even if you showed me studies to prove that, I would continue to aspirate. The way I see it, it would be a shame to die a sudden death over some muscle
Thats fair and all. But there's been medical studies (i've linked them before but to lazy to find em).
So your statement is bit wrong because.
1. You wont die from injecting air, it simply expelled trough your lungs. Worst case scenario (with far more than 5cc of just air) would be shortness of breath for 2-3 minutes and back to normal.
2. You also wont die from injecting testosterone into a vein either.
Think about it...nurses or doctors dont aspirate anymore, who has done more research and would have come to the conclusion its not only safe but better? The medical field as a whole or internet science?
