    Are you sure about subQ? I just asked my hrt doc last week. He said testosterone ok for subQ, but B12 has to be IM. Would sure love it if he was wrong. Can you please provide some backup to this claim?

    I inject it subQ twice a week. Only time I go IM is if I mix it with oils. I have no idea where your doc came up with that nonsense

    Strong claim and Docs can be wrong, but since my Doc is one of the top hrt docs in the U.S. if not the world I'll stick with his opinion until I see strong proof otherwise.

    And by all means prove him wrong. The truth is all I care about. Don't worry about ruffling my feathers

    Not a strong claim. Very common. Here's is my prescription vial, as HRTstudent stated, it clearly states for IM or SC use.

    I think your doc probably just prefers IM. but if he is saying no subq whatsoever, he is very far from 'top doc'. This is very entry level knowledge.

    He never said "cannot". It may have to with which he believes is more effective.

    Here's the results of my last 3 blood draws the first was before I started, the second was injecting 1000mcg every 10th day, the last was 500mcg every 10th day. IM of course.

    Vitamin B 12 (800 - 2000) "390", "1230", "808"

    Would you be willing to share your labs? If your numbers are good doing subQ, I"LL SWITCH STARTING TODAY !

    Next time I talk with him I'll ask why he wants IM. Don't really want to get into defending him, but look him up: Dr Rothenberg. He trained alot of the top HRT docs in America and is very well respected in the field of HRT.

    I'm not really concerned with your doctors credibility, I just wanted to give you info that you're more informed when speaking to him. I think you guys just had a misunderstanding is all.

    Your test was for B12 looks like unsaturated serum binding capacity (based on those ranges), not B12 serum levels. Serum levels ranges are generally 200 to 1000 pg/ml.

    My levels aren't really something you want to compare to. My results show >1100. I use B12 more than most desire to. Sometimes up to 1000mcg daily.

    I inject subQ if all Im injecting is B12. If I mix it with testosterone, I go IM. Because I don't like injecting more than 1/2 CC subq. So I alternate depending on what i'm injecting that day.
