I just had my 4 week trt bloodwork results come back. Everything came back normal. My total t came back at 600. I get once a week injections of Testosterone at 150 mg a week. The lab draw was taken right before my weekly shot so it had been a full 7 days since my prior shot. (I go to the office for injections, thus injecting more frequently is not an option). On another forum, I was told this probably means (though impossible to tell without bloodwork) that at the beginning of the week right after my shot I am probably at the upper end of normal (1,000) for total t, then it drops off later in the week, especially after the 5th day. Is this true? Also, while I know getting shots more frequently would be more ideal, for someone who is only able to get shots once a week, is a 600 total t after 7 days mean I am probably at optimal levels (i.e. above 800) for at least the first 5 days of the week after my weekly shot?
