Just to confirm, sorry...

What virus are you concerned about that would survive in large enough numbers to cause you issues that wouldn't also just be in the air in what ever room you're injecting in? If you have a specific concern, I might be able to find someone with expertise who can address it.

I mean, you do you. But there are 10s of thousands of people injecting this stuff every day without any filter.

Not a particular virus, but just general QC concern. Plus some pathogens can take a long time to show themselves.

A few thoughts on this whole filtration rabbithole:

1) As someone relatively new to this, it’s hard to know what’s truly necessary. What would help ease that uncertainty is some kind of consistent voice from the community—but that’s not what I’m seeing. After doing my homework, comparing vendors, and placing an order based on what seemed to be a solid reputation, I then came across threads harshly criticizing that same vendor. The level of disagreement makes it tough to know who or what to trust, and as a newcomer, I can’t assume that any advice is universally reliable.

2) This is, at the end of the day, gray market territory. We don’t really know what’s in some of these products. There have already been reports of contamination, which makes it clear that proper handling isn’t guaranteed. With that in mind, I see little downside to exploring extra precautions.

3) When you compare the cost of peptides through a U.S. pharmacy to the cost of basic lab equipment, the equipment starts to look like a pretty modest investment. I've already spent thousands at my local pharmacy, and if I’d taken this route earlier, I could’ve had a solid setup by now. Plus, much of that gear is a one-time purchase—not a recurring cost.

I’m not saying any of this is necessary. I’m just acknowledging that I don’t know for sure—and with all the conflicting opinions I see, it’s hard to rely on anything but my own judgment.

At what point do we filter out the peptide we are seeking?

as of a few months ago Jano stated he uses 0.22um and TrustPointe uses 0.45um filters for HPLC testing to prevent damage to their equipment.

Tirz is roughly 5kDalton which is roughly 1nm (0.001um)

No, I understand where you're coming from. Which is why I'm trying to ask pointed questions to help you think about it.

1) Agreement is never going to happen. And you shouldn't take everything I say at face value either. The best thing you can do is ask someone WHY are you stating something. What knowledge or experience are they basing it on. I'm an engineer not a medical professional. What I will tell you, is you've just barely started to scratch the surface of this community.

2) Agreed, but some kinds of contamination are more likely than others. Also, what is the consequences different kinds of contamination. What about heavy metals, what about endotoxins. (These are also not a concern, but at some point you should learn why they aren't)

3) It definitely feels that way when you're getting started. But I also don't believe in spending money for no good reason. (And I'm one of the rare few around here that could easily afford to pay full pharma prices)

To put it in perspective, I think most of the experts would liken using a centrifuge to walking through the park with a motorcycle helmet on. Are you safer? Theoretically...
