Hi Gybryl. Please can you check you have the 50mg dosage right? 50mg sounds like a large dose.

Ampoules usually have 1mg, 1.5mg or 5mg in 1ml or 2mls of fluid.

Oh, and...ampoules are for single injection use only...I wouldn't use as multi-dose.

Thanks for reply,ya i check again and ampoules are 500mcg wich is mean 0.5mg isn't?Thanks for quick answer

Yep...usual dose for B12 injections is 1mg, so you'd need two ampoules if you wanted to take the 1mg B12 dose that is usually prescribed 👍
