Trouble getting pep into pen catridge with filter

[cookieguggleman]

Ugh I need some advice—I'm trying to recon a vial of ARA 290 into a pen cartridge with a filter and I'm almost at the end, trying to filter it into the cartridge and it WILL NOT BUDGE through the filter. Tried using a really low gauge luer needle, too. Any thoughts on why or what to do? I'd REALLY like to filter it (I forgot to wipe the vial top with an alcohol wipe🫣)

Anyone experience this? Is it this particular peptide?

This happens to me with the Tisch 4mm filters frequently. Try a new filter. . Some just seem to be difficult. I wet mine first with bac water, which seems to help, but not always.

Thank you. I asked Chat and chat said ARA 290 doesn't filter well, it sticks to the filter and clogs it instantly. So i'm going to go commando with this one.

Which ones do you have the most success with and are quality filters? I've started thinking about using them, but I've read that some brands have a high clog rate. Some as high as 25%. I've also looked at some high quality ones, like Fischer Scientific, and they can cost as much as $10 each.

Though Uther suggests PBS as a buffer for ARA, Gemini and others suggest a pinch of sodium bicarb instead for ease of filtering.

I don't know about ARA, but I had trouble with reta, mots etc.
It helped to have an extra needle in the cartridge, for venting, did you do that ?

I don’t know what that means… Does that mean adding it into the vile? And how much?

Vent needle is important... Without it you risk pushing the stopper right out of the cartridge. Ask me how I know...
