Forget about what is considered a common starting dose as everyone will respond differently to the said dose of T.


Sure most men on trt are injecting 100-200 mg/week in order to achieve a healthy TT/FT level which will result in relief/improvement of low-t symptoms and increased overall well-being.


Do understand that although your weekly starting dose may seem low that there are some men who do not need higher doses.


As I stated in your previous thread levels will be in FLUX leading up until they stabilize (4-6 weeks) and it in common to experience ups/downs along the way as your hpta is also going to get shut down.


Your blood work will be done soon and then you will see where said protocol (dose T/injection frequency) has your trough TT/FT/e2 levels and if by chance your TT/FT levels are still too low then you will need a slight dose increase/injection frequency.


If you need to bring up your FT levels than going from 75-100 mg/week would be a sensible jump unless your levels were very low (doubtful) than a bigger increase would be needed.


Keep in mind that going from 75-100 mg/week that an increase of 25 mg will have a big impact on increasing your TT/FT levels.


I have seen a 300 ng/dL jump in my TT when the dose is increased by 20 mg/week.


Keep in mind that you also want to see what impact your current protocol (75 mg/week) has on increasing your hemoglobin/hematocrit.


Any time T dose is increased it will result in driving up your RBCs/hemoglobin/hematocrit levels.


Just wait until labs and then decide if any adjustments are needed.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
