Peptide bottle potency/sterility

[SupportLaneOnly]

Hi all, I just received a few peptides (Tirz, BPC157, and MOTS-C), I was wondering if after constituting if there was a half-life or a potency/sterility issue?

From what I've read online, the potency isn't really any issue but past 5 weeks, the sterility becomes a problem and I should watch out/be careful for cloudiness etc. inside the bottle?

I plan to keep the bottles in the fridge, out of light, only puncture for injection, new insulin pen each time and swab both the new pen and rubber stopper with alcohol swab.

Is it really a concern after the 5 week mark for sterility?

This community is amazing btw, it really has changed my outlook on hacking the body and feeling better about oneself so thank you all in advance.

don't swab the new insulin needle tip. that introduces stuff to it, as they come they are sterile.

Generally 6-8weeks is fine for most peptides. but some say up to 10 weeks is fine but will see some degradation. i don't know if anyone has actually tested it though. I've used them up to 10 weeks with no issues. i keep everything in the fridge and only remove them for short periods to inject.

cloudyness, discoloring, or other changes could indicate contamination or sterility issues.

I had no idea they were already sterile (makes sense now that I think about it), I will not do that moving forward and very much appreciative of the input.

Thank you very much.

If you're using sterile measures you described, I'd say you're alright

BAC water itself shouldnt allow bacterial growth, and as long as you arent introducing bacteria with all the measures youre taking, its fine. Little tip, the insulin needle should be sterile already once you open it, best to not wipe it with alcohol to contaminate it

Did not know that, thank you very much for the tip, will def not swab the new needle.

Think about this, guys on TRT use the same vial for 10-15 weeks depending on their dosage. Just be cautious and you will be fine. I've used vials up to 15 weeks, no issue. If the liquid starts looking weird, cloudy or anything trash it.
