To filter or not to filter, that is the question

Do you filter your peptides?

Yep. Purity tests are about looking at the state of the peptide. Degraded aggregates, incomplete synthesis, etc. The way the tests work doesn't allow for it to test for purity in the way people tend to think.

 
I dont bother filtering. Imo if it's lyophilized it's already filtered and sterile enough for me. Ive done worse. I've already died (twice). I'll take my chances.
☆I respect that that everyone does not feel the same as I do. We are all entitled to our own thoughts opinions.

Thanks for those screenshots, My immediate thought was heavy metals. That eases my mind somewhat but I still might look into filtering. I'm not in the medical field or a chemist so there is a lot I'm still learning.
 
I am beginning to think that I get fewer ISR's when I filter. I'm trialing this hypothesis with SS31 today, I had to stop pinning it because the ISR's would burn/itch for like a week. They usually hit about a day after I pin. After a two-week break I filtered a fresh vial and hopefully, no ISR tomorrow.

I was limiting filtering to anything I put into a cart because it will be around more than just a few days. I might start filtering everything to see how I fare.
 
I've only been filtering my tirzepatide, because that's what I've read about.

Do you all filter your GLOW? Haven't done enough research to understand if it's OK or not (meaning if using .22 filter will not mess with the compound effectiveness).
 
i don't like that. test it they way you get it.
They can't.

If there's any (relatively) large particulate matter in the vials it's going to get stuck in the columns and ruin them. It won't show up on the HPLC either way, but this way it will also cost thousands to fix.

(Paraphrasing from memory their explanation, this is the limit of my understanding).
 
Thanks for this post. Had not been filtering but after reading up on the subject due to these posts, I have ordered filters starting asap. small price for peace of mind. As a doc I am always reminded "do no harm".
 
I see some discussion about filtering peptides. If they are 99% pure, then what are you filtering out? One of my worries is introducing a contaminant.
All the testing facilities filter first before testing the purity. Besides that, they are testing the purity out of just the peptides present, not all the substance in there (of which only 1% might be peptides)
