I use the slin pins up to 2 times IM if I'm doing bilateral shots , Sub Q, 4 times ,after that it hurts too much, and you're right you end up spending more on pins than on the goodies if only used once, just be sterile with the whole process . Blessings, Minister.
agreed, think about some of these protocals of peps 3 times per day, plus bi lateral IM's, that is a possible total of 5 pins per day and that could go higher, that is around $50 per month on darts!!
