"mainly stuck with the tabs due to the injection pain I have heard of from the liquid. "
I don't understand what the problem is. I use Zambon Winny EOD without incident. I use a 22 guage needle and stick it in my ass alternating cheeks. There are no nerves, no major blood vessels, very low risk of hurting yourself. No matter what, ingesting a 17aa substance is worse for you than injecting it. I know the thought of piercing your skin with a needle can be a bit daunting, but it's only daunting the first time. I was definitely anxious the first time I did it but after that, it's not a thought.
It's almost like you have to say to yourself, ok, if I'm gonna do something as serious as dope my body with an anabolic steroid, I have to be able to be tough enough to stick a tiny needle into my ass. The pain of the needle is so minute it's not even worth writing about. Your muscle is a bit sore for the next 12 hours, but after a few times you don't even notice it anymore. It's such a non issue.
Regarding buying needles- in order to stop the spread of HIV, NY state law (and some other states now) allow you to buy pins at a pharmacy with no prescription and no questions asked in packets of 10 or less. Just ask. (They will think you're a heroin junkie so don't do it in your own neighborhood).
Long story short. Don't believe the hype, stick yourself with a pin and save your liver some stress. An added benefit is that you don't miss a dose because you can always tell the last time you injected by just touching your ass. If there's a dull pain, you just did it, if it's gone, it's been a day for that cheek.
