I am new to this community and I found it by searching for "B12 Australia". I am B12 deficient and I notice that the availability of Methylcobalamin is a topic of discussion. I am able to access injectable methylcobalamin from one specific GP in Perth. The methylcobalamin is manufactured in Melbourne and comes in vials of 10,000 ug in 2 ml. The manufacturer is Biological Therapies and you can contact them on (03) 9587 3948. I found the local GP (my supplier) by contacting the manufacturer directly. The price per vial is about $25 and one vial lasts me about a month. I inject about 0.2 ml every 3 or so days using insulin syringes.

Prior to finding this supply of B12 I used the standard cyanocobalamin injectable for a while and also tried some Methylcobalamin from USA until Aus customs stopped a package getting through (with only 1 bottle!).

Methylcobalamin has assisted greatly with my recovery from depression but it also had some spectacular side effects.
1. I had been diagnosed with Asthma at age 4 and I was on daily medication until 2 weeks after taking B12. Havent had asthma medication since.
2. I had a fluttering upper left eyelid for a couple of years - totally gone after geting onto B12
3. My receding hair began to re-grow on my forehead and in my thinning top area. Confirmed by both my doctor and hairdresser.
4. My fingernails went from chalky to strong and now grow at twice the previous rate.
5. My eysight was deteriorating fast at the time of diagnosis but the deterioration halted and has been effectively steady since.
