Phenol vs BAC

[Labcat]

Curious if anyone uses phenol/water as their preservative to recon? It’s supposed to be a much stronger and broader spectrum agent.

Or both phenol and BAC? (I read it is how insulin, the classic peptide, goes beyond 28d)

I don't know why we'd need a stronger and more wide spectrum bac agent.

If benzyl alcohol is good enough for pharma, it's good enough for me.

That’s one way to think about it, but it’s not really true about pharma?

My vials I just got from pharma use phenol.
Mounjaro kwikpen uses both.
Zepbound has neither.

So there must be a reason, and it might make a difference depending on my situation (my usage pattern or maybe the cleanliness of the powder I get).

Of course it's true.

Pharma uses BA in some medicine.

Pharma also uses phenol in some medicine.

One does not negate the other.

Theorycrafting this sort of stuff is fine, but I'd catagorize it as overthinking. BA has been demonstrably fine in both pharma and gray use cases, changing it up for some theoretical benefits is a waste of time.

I asked whether anyone is doing it,
but thank you for your opinion

You're welcome.

Don't neglecte everyone's own risk tolerance.

I don't lock my door, but I won't try to convince others that having security cameras is useless.

Benzyl stops the growth of anything it touches, but does not kill anything.

Phenol may be better in some cases, but its harder to obtain (at least in Canada).

If its also hard for you to obtain, you're best bet would be to strengthen your sterile standards/procedures.

Some tips for you :

• split into single dose aliquot
• reconstitute in a clean room with as little as possible air movement.
• clean everything you use including your hands twice.
• avoid reusing the same needle/syringe when reconstituting.
• use syringe filters.
• work fast.

Its not possible to get to 100% sterile, but these tricks may help you.
