First pin is in the bag. 500mcg was 7.4u based on the pinch of an overfill in this vial. I'll only be dosing in the AM and will go outside to get some sun on my face for a few minutes after pinning as there are reports of this helping. I'll go into this detail in my next update post. Short on time today.
Injection was painless. No sting. No injection site reaction at all such as welts or redness. Almost as big of a nothing burger as Reta, which for me Reta is the most painless pin around –– like it never even happened.
