I inject 1000 mcg intramuscular weekly. I am thinking of upping the dose because I haven't noticed anything substantial yet. Been takingit for a month +.
You probably are aware bro that inject B12 doesn't stay in your blood for that long, so don't expect an injection on Monday to give you a boost on Saturday. If I understand your post correctly, I wouldn't suggest boosting a single shot concentration too much higher than what you are already doing. Consider multiple doses per week, see if that helps.
Also, all in all, B12 is pretty safe, but you still don't want to use indiscriminantly. If you use the injectable at high doses consistently for too long a period of time (really hard to say what that is - months, years, ?), your body may become dependent/accustomed to the inject B12 (intramuscular) and the ability to absorb the protein bound form starts to diminish (which is already low). This is one reason why I don't particularly advocate long term injectable B12 use, but it in the short-term, it sure is useful and helpful to me when I need a boost for leg night or a race, plus I have had bouts of anemia.
Note, there are a lot of different opinions and research on this, and you can certainly find out a lot more online. A LONG time ago I learned this feedback from a doc after AAS became illegal, and he switched from giving me cypionate to B12. Obviously wasn't the same.
You can also e-mail/contact AG guys if you have any more specific questions about dosages and usage, or consider a PM to one of their reps on the board.
