Yep you will get aching, and more than likely it is because the skin and head are getting stretched! Adjust dosage to avoid prolonged erection and ENJOY!

Complications are a risk but a risk I'm taking for a HARD ON!

Yep, I've injected two days in a row as well.

Welcome! Lots to read about here on FT.

Sorry I sometimes use 5/16. Anything shorter may not work for most.

I don't think anyone needs a 1/2 in needle to get into the cavernosa. I've recently read using the shorter needle creates less damage to the tissues, just "bury" the needle to the hub. I stretch my penis when injecting to "even out" and insure a good penetration, usually closest ...

A typical 1cc syringe is 100 units. It is clearly marked in the syringe 10 =10 units, 50 = 50 units as so on. If you need 45 Units draw to 45!
Yes it is supposed to freeze solid, when you need a dose thaw it, draw the dose and refreeze vial.

I believe you're right. NOBODY has skin or tunica so thick that a 5/16 BURIED needle can't make it to the cavernosa.

I injected there this morning. One thing I noticed was no ache at the injection site like i get when Injecting near the base. I'm cut so I have more than an Inch from the glans thats thinner skin. Yes, nice to know I have another "target".

Ok, I'll give that a "shot" and post my results!
Thanks!
