I'm finding the .3 cc pins don't have as much suction and the IGF-1 sticks on the sides, bypassing the plunger and staying on the body of the syringe. Seems like a lot of waste.
IS THE 1CC syringe volume even better than the .5cc for IGF-1 (reconstituted in AA)?
And, is 29 ga. too small for Jin injections?
