Well, now that is a little bit of an abuse of statistics. I understand your point, but comparing a filter on a peptide syringe and Russian roulette is kinda the definition of a strawman argument. While dying from Russian roulette is always 1 out of 6 (assuming revolver, etc) each and every time you do it, I am pretty certain the odds of dying from not using a filter on a peptide is a little different. I would go so far as to say that no one in this forum can give accurate safety data on it. I think the take home here is 1.
@Augu5+1ne was not hugged enough as a child and 2. Filtering, while always should be a part of best practices, should be implemented at a user level based on their comfort with both the perceived and real drawbacks to not doing it.
