Question regarding injections I was one once every 2 weeks 400 mg which I know is not good etc.. 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.
