So.
Amp for water.
Vial for hgh Powder.
"Opening" a vial is just removing the cap to get access to a rubber membrane.
You draw water from the amp and put this water in the vial by passing through the rubber of the vial.
You wait for the mix to be clear and then you draw the amount of hgh you want (0.1ml is 1ui if you put 1ml of water inside)
The rest of hgh stay in the vial that you put in the fridge for next time. Rubber protects against external pollution.
Don't forget to clean with 70% modified alcohol before piercing the rubber with a needle and afterwards as well. The same goes for your skin.
Just look for "peptide mix" in YouTube.
Something like that:
