Just an update that due to a cancellation my appointment was moved from late March to today.


I have been prescribed a starting dosage of 140 mg of test cyp per week.  I asked if I could split that in half and go with 70 mg every 3.5 days.  He said I could do whatever frequency I wanted as long as I hold to the 140 per week total dose.  He said to let him know if I feel any sides that could indicate he needs to control estrogen.


I just injected 70mg of Pfizer in the right quad tonight.  Used 18g to draw and 23g to inject.  The cost was only 6 bucks for the 10ml vial with my work benefits. 


I will have bloodwork done in 4 weeks to check levels and the doc will adjust dose if required.  He wants to focus on my free test getting to upper range of normal  -  about 600 pmol/L  - but will back off if sides appear.



Unfortunately, as noted on their website PEAK is no longer accepting new clients.

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.
