At almost 3 weeks from my last Cyp shot my total T was 18. That's with low dose opiate use as part of my pain mangement regimine which crushed my T to begin with.
If I ever have a question where my blood work stands I always get my tests done through private md first. My doc doesn't get when tests should be done I regards to injection time so any high tests I have had screwed up my doses for rest of year. I don't leave anything to chance now since being at 750 plus T levels has really made a hughe diffence for my quality of life.

How old are you? There's a much easier way to drop your levels with out using test.
My last time I went to blood work my test levels were 86. I did it to get my dose uped

My test is usually a little higher in the morning and drops through day so later in day may also lower you a few (not many) points good luck feel free to pm me if I can help in any way like t-luva said you really don't want to start if not needed but has made huge difference for me

I've gotten results back in as little as 2 days. Just plug in your location where to get blood drawn. You'll keep the Dr out of it until you feel ready....

Not a problem bro, anything to help when I have the experience and knowlege to do so. I tell ya what tho since I've gotten on TRT every aspect of my life has gotten way better, I feel like I did in high school and before I started abusing my body with bullshit. Definitely worth it.
Now as for getting blood work I've seen some peeps on here talk about being able to get private blood test done, not sure how that works or what it's about but I'm sure someone on here who has done it could lead you in the right direction for that which would help you find out your levels before you go to the doc and get your levels checked.

Have you gotten blood work done at any time in the recent past that shows your low test levels? If so what was your level?
I am currently on TRT and will be for the rest of my life, due to heavy heavy opiate abuse for around 7-8 years, along with a few other reasons my levels plummeted to a whopping 200.... At age 30, yeah it sux. After rehab and rebuilding my life for a year and working out and eatting right and all, things just didn't feel right, so I got blood work done and that is what my test level came out to be. My doc explained the reasons why this was and that my best option was to go on the treatment.
I would say 2 weeks is a correct time lapse for your level to be low but I wouldn't recomend trying to get on TRT if you don't have to. There are many other ways to increase your test levels naturally, if you haven't jacked up your free test production to no return.
