Filter Loss - Am I Doing This Right?

[not-today-scale]

Hey all, just started using filters on my peptides and I'm noticing a significant amount gets left behind – like almost a full ml. Is that normal? Seems like a big waste every time.

Yeah, that's the solution stuck up in the filter. I usually push it through with an extra half ml or so of bac water.

 

[not-today-scale]

Awesome, good call. I was overlooking the obvious lol. Thanks!

That's why I like pre-measured extras. Even if you lose some, you still get the amount you paid for.

I talked about this when I mentioned filtering, but someone told me it was just my imagination, even though you can CLEARLY see the peptide in the filter. I prime and flush, but it's hard to tell how much is really in there. Someone claimed they knew how to avoid absorption, but I bet she isn't using your typical filter. I'd like to know her secret.

A ml is a lot. Are you using a huge filter? Here's the breakdown on filter size:

The goal is to use the smallest filter possible since peptides get stuck in it. Small filters like 4mm retain only about 0.07ml, while 13mm filters hold about 0.28ml, and larger 33mm filters can soak up 0.65ml.

In practice, you should be using a 4mm filter if your solution is less than 4ml, or a 13mm if it is more. I also pre-wet my filter with a little extra BAC after reconsituting. I take off the recon needle, put the filter on and push the liquid through.

That's what I do too! Smart minds think alike!

Are you using a huge filter?

Yep, you're right. I was using a filter that's too big. I appreciate the heads up!

I'm not a fan of overfills personally.

 

[Glp-Won-Kanobi]

So, like, a 4mm filter is the way to go? I think mine might be too big too then.

But you can avoid any loss! Just flush it with bac water that's equal to the amount trapped in the filter. There ya go!

You'd have a point except people like Alice actually track what happens. If you get steady weight loss at 1.5 to 2 per week on a lower amount with no side effects and no weakness, why bump it up and invite more problems?

 

[Cut_xx]

Wow, you cracked the code! Tell everyone!

 

[not-today-scale]

Exactly - flush with more bac to make sure you get the most out of it. Then measure the final volume (using a fresh syringe, no need to remove the needle) to get the exact concentration.

 

[Driftwood_99]

I was stoked I got all 6ml through the 4mm this time without it clogging or bursting.

 

[Cut_xx]

I'm new to this. Do you need to filter Reta or Tirz? What IS a filter anyway? Where do you get it? I'd just figured you add bac water and inject. Sorry for the dumb question.

 

[Driftwood_99]

It's good to filter out any gunk. The link in the link is a filter you can use for GLP-1s.

 

[Cut_xx]

I'll order some. Thanks!

 

[Tone-Tale]

I figured they meant 3-4 units, not ml.

Do the 4mm filters come with a pre-filter by default? My 13mm ones from Cobetter had a pre-filter (0.65+0.2μ) but I'm wondering if that contributes to greater loss. Does anyone know?
