You could try weekly injections of 10-12mg. But that will peak and wear off. Better injected twice a week, but injecting 0.025-0.030 ml of 200mg/ml twice a week might seem odd. T creams work OK and allow a daily dose. Best applied to inner arms and as I indicated above. Need to not apply then gym, sweat and shower loosing the transdermal before it absorbs. My wife has been using T-creams with her HRT for years.
100mg/ml T cyp/eth might be easier to manage than 200mg/ml.
Inject SC, not IM, with #29 1/2" 0.5ml insulin syringes. Pinch up a fold of skin and inject into the end of the fold, needle parallel to muscle. After injecting, press finger on injection side for 10-15 seconds to allow vessels to close off to prevent bleed bruising.
What T levels should you have? There really are not good known levels for female hormones as these vary greatly from one woman to another and then change drastically during the month. With T, you need to watch your confidence, libido and assertiveness and try to see that through the fog of your changes during the month. Female HRT is very difficult as lab numbers are not really that useful. My wife and I have been through a lot over the years.
Speaking of labs spot-on: Thyroid lab numbers are insane. TSH should be near 1.0, T3, T4, fT3, fT4 better near mid-range. You can best eval overall thyroid function this way:
Evaluate your overall thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid hormone fT3 is what gets the job done and it regulates mitochondrial activity, the source of ATP which is the universal currency of cellular energy. This is part of the body's temperature control loop. This can get messed up if you are iodine deficient. In many countries, you need to be using iodized salt. Other countries add iodine to dairy or bread.
