I may be wrong but I don't think you want the injectable.
Apologies for jumping into the middle of the conversation, I'm not sure if the discussion is regarding using it as an injectable.
But...you can purchase the injectable, pull out the required human dose with a syringe, squirt it into a liquid (juice, etc.) and drink it. For human use it's not used as an injectable, just an alternative to the horsepaste or the expensive pills.
Seems to have worked for some people; taken orally or even rubbed on inner wrist. I am working on collecting info just in case.
The injectable for is fine but you have to calculate the correct dosage because it is more concentrated.
I think you technically could inject it but that is not required.
You drink it.
