Any tips on how to properly inject glutathione using the syringes? I’ve tried over 10 times and still can’t seem to get it right. Is anyone using a different syringe length that works better?

Just good my Peptides's in!!! I ended up buying 5 of the amino should I fill them all up now with the B~water and put all in the refrigerator or should I only fill them up with the b-water when I need them? If the second do they stay outside the refrigerator or inside ?
