Filter Loss - Am I Doing This Right?

[roundtwo-ish]

Wow, I feel dumb, Two-plus years of peptide research and filtering never crossed my mind. I keep wondering whether it's a scheme to get you buying extra stuff, no offense lol. Is this really what you do for every single vial?

Tone-Tale I don't flush either, and I think some folks skip it because peptides cost what they do and 10 to 15 units is not a big deal. I followed the video I watched when adding those steps. The two peptides I most recently filtered will be finished or discarded before the vial runs out, so I figured I did not need every last drop. I am also not on anything expensive right now. For something needing lots of pins and pricey, like tesamorelin, I'd be more frugal and push that holdback through. I've another peptide coming that I'll reconstitute with 3 mL of bac, and not flushing the filter for ten or 15 units, it isn't worth the effort or added contamination chance.

Peptide molecules are vastly smaller than a 0.22 micron filter pore, so filtering can't remove them. Whatever stays in the filter (I never flush mine) would make the solution more concentrated, not less. Are you asking hypothetically or did it actually happen? If so, more details would help.
