Question regarding injections I was one once every 2 weeks 400 mg which I know is not good etc.. :mad: I have changed to Monday and Thursday 100mg each injection. If I did one weekly injections of 200mg would that make a big difference?
 
I've never done once weekly injections, I do know it will cause spikes in your testosterone levels and more problems. Higher estrogen levels, injecting twice a week will keep your T levels nice and even.
 
Injecting once a week in a general sense would have youre T very high for ~3.5days and then would taper off to very low the end of the week. Twice per week is the commonly accepted bare minimum to give you a smoother ride on TCyp. The half-life of TCyp is about 72hrs, reason for the 3.5D dosing.
 
Definitely stay with 2 injections a week for best results. Consider using insulin syringes and injecting in the shoulders - you don't even feel them that way.

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.
