@Neil-McCauley
Just picked up two gansulins, hoping virgin needles will be more gentle..
They'll always be superior, its one of the advantages of using a pen, fresh needle. I can tell a difference myself, when I get to the end of a bottle, often I will just pop the vial cap off (I have pliers specifically made to do this) and insert syringe directly into peptide and pre load last 2-3 dosages to empty the vial out, not going through rubber stopper.
Those fresh ones I can tell never give my rat any issues, always clean injects, no bruising
