    b12: subQ or IM

    I have been researching threads on this for a little while and notice there is a good bit of debate between the best method of administration for b12.

    I noticed though that the PDR states that b12's best method of administration is IV, then SubQ, then IM, i would like to go the SubQ route as it will cause less scar tissue and has a slower, more controlled release.

    My question is how would someone go about injecting 1cc or over SubQ, i figure a slin pin would be the best method but is it possible to do this?

    i have no problem with that, its just that if i'm gonna be doing ed or eod injections year round id perfer to be able to inject subq as well to limit scar tissue

    i'll prolly just get some 5000mcg/mL cyano so i only have to inject 20IU and just slin pin it

    To bump this thread. Does it matter if it is B12 or a B12 complex?

    Phate, my man ! B12 is one of those vits. that if u take it today and wont take any for the next 20 years. Then test urself on b12 presence - guess what ? U'll still have it in your system. Too much of B12 isn't good too. 5mg is a big dose - not human, probably bovine injections.Am I right ? Even with B12 deficiency there a special schedule of injections u should follow. Too much of b12 is a guaranteed stones in your organs bro.

    Oh yea , there's no B12 complex I believe. Vit.B complex that contains B1,B2,B6 and B12 that I can understand, but VitB12 complex ??? Right now I know there's a methylated version which is way better and more effective, but I dont understand why would anyone mixed B12methyl and B12 cyancobalamine to make complex out of it.
    You probably misprinted my brother !

    1) i said i take B Complex, which has all the b vitamins and cyanocobalamin for b12

    2) B vitamins are water soluable, not fat soluable, so you can't overdose and they are excreted out of your system quickly

    3) methylcobalamin is the version you are talking about and you are right that it is better, just very hard to get

    4) my b complex is 1000mcg/mL, i was going to get 5000mcg/mL so i could subq inject a very small volume and still get the dosage i wanted

    Are you set on taking 5,000mcgs? The body can only use so much of it so you are probably going to waste quite a bit of that out. I take 1,000mcg Every Other Day and that is more than enough

    not at all, the reason i wanted to get 5000mcg/mL was because i shoot it subQ and that way i would only have to shoot .20mL instead of 1mL. shooting 1mL in a subq shoot isn't a good idea and i would have to waste alot of pins and syringes by doubling up on the injections

    i shoot 1000mcg daily subQ, isn't the only difference here the rate of absorbtion

    it's not that big of a difference though IM or SubQ with B12 I use slimpins so it just barely makes it into the muscle but thats how every doctors office I have ever been to give B12, I don't think you need more than 1,000mcg daily and 1ml is fine SubQ or 3mL IM (max)
