BAC vs Sterile water for Tirzepatide?

That's very true. My real question was why they're both called bac water when just one actually qualifies as that - seems like an unnecessary risk to put people through. Could you tell me where you're getting your hospira? Is that something sourced here on the forum?

Ive tried a bunch of BAC waters, Amazon ones, other brands and Hospira. My 30ml vial never lasts a month anyway, and even the last dregs after mixing have caused me no problems, and that peptide holds up to 2 months. Could be luck, but I honestly think the Hospira obsession is just hype.

So BAC water is apparently either unavailable or costs around $80 a bottle? We need an alternative. Even the UK only just got regular stock of the standard brand!

dozydabbler Mostly I've used hospira. I also tried a 10ml bottle from a different source and it was fine, plus some little 3ml kits. Now I have some nacl bac water I'll try on my tirz.

go with the bac. the benzyl alcohol in it is a preservative so a vial can be drawn from over and over, plain sterile water has none so it's really a one time thing once you poke it. just make sure it's a sealed vial with the stopper intact, brand matters less than that

Thanks, already deep into researching this myself. Running 7.5mg of tirz currently, so a 60mg vial should work out fine size-wise. Read somewhere that the powder needs freezer storage, is that actually necessary given it's lyophilized? One snag though, Hospira water just isn't available where I am in Germany. Thinking about placing my first order through one of the sources people here speak well of, hoping the BAC water quality holds up.

did some more digging and the general advice seems to be stay away from bac water that comes from random sellers. now im just trying to find bac water that'll actually ship to japan. since reta is where im starting out, figure a couple of the 30ml bottles should cover me - hospira or one of the other two you mentioned, genetek or lambda.

congrats on getting started! for uk-specific bac water options, it might help to ask around in the european crowd here, people there tend to skip random sourcing in favor of stuff that's actually been tested and proven reliable. i know hospira in particular is tough to track down in your area, and bac in general seems less common over there compared to other reconstitution products. wishing you the best with it!

Justinb always found it odd that folks stress so much over pharma grade mixing water when the peptides themselves are research grade to begin with. making sterile water correctly is honestly way simpler than making peptides properly. the bigger pharma bottles get stretched out over months by most people anyway, so by the end they're not really pharma grade in practice either. i've switched to smaller research grade bottles from legit research sellers and it's worked fine for me. early on i grabbed a generic unbranded bottle from an online marketplace and ran it for a whole year, though honestly knowing what i know now i wouldn't do that again.
