How do you put the Pep “Inside” the dang syringe?? It will not go inside the syringe no matter what needle I use. I tried a 5/16 one and then a 23G 1 inch reconstitution needle from Amazon. I’m bummed!!
Do you mean injecting a peptide into a LL barrel? If so, I find I have to pull down slowly on the LL barrel plunger while I'm slowly pushing the plunger on the syringe. The pulling creates enough suction to pull the peptide into the barrel.
