You never have to aspirate bro, that's old school which isn't even practiced in hospitals anymore.
You can literally inject 40cc of air straight into a vein and nothing will happen except short of breath and violent coughing for 1-3 minutes.
Plus, to actually hold a vein you need to be at 90 degree angle and not a 180 straight above, it's not as easy as people think, why do you think all junkies have so horrible veins? (yes some is fentanyl but not all of it...)
What? That's just poor planning on your part, 4 weeks is ending any cycle, how are you handling injecting prop during the vacation?
I don't think 500 iu per week is enough, I personally do 1500 iu split on 3 injections and I feel so much better and so does my balls lol. It also helps a lot with the shelf life, each 5000 vial ends up being used in 3.3 weeks and shelf life is about 30 days, so playing it safe and helping my balls more, win win
If you do for example 500 iu per week, thats 10 weeks and 6 weeks over the shelf life, which means you could almost inject water and get the same result for the last 5 weeks or 10 injections... 1000iu per week is 5 weeks, which means you'll be one week over the shelf life. Food for thought.
Of course you could pre load and freeze and avoid the shelf life issue but damn, not worth my time, that's for sure.
Could you explain this vacation thing because its weird to start a cycle and then just bail on it for 4 weeks, like, you will feel like total shit lol...
