I second LordKat on the rules re: the first question, but I will answer in terms of frequency:
1. How much T you are injecting or (in the case of cream or gels) rubbing on? The frequency of injections or applications (weekly, monthly, every other week, etc.).
Pre-filled syringes (Enanthate) every 18 to 21 days. Most guys typically use the dosage that I'm on at bi-weekly frequency, but I've been on 2 1/2 to 3 weekly injections since I started and it's worked fine for me.
2. Your last measured blood levels of T? Provide details like bound versus unbound if you know them and only if you want.
Testosterone: 16.9 nmol/L (reference range 8.0 - 30.0)
SHBG (Sex Hormone Binding Globulin): 33 nmol/L (reference range 17 - 66)
FAI (Free Androgen Index): 51.2 % (reference range 23.3 - 103.0)
3. How you are feeling?
I feel fine, though I've been on T for over 2 years now. I can always tell when I'm due for an injection because I break out with acne.
