Cheap Pfizer/Hospira BAC may be about to end

It's a tough one..cause some peps like NAD+ are better at higher ph..and don't want to use something like 5.7..then you have some that do better in lower ph...like Glutathione...The last thing you want is to use the wrong ph..and make your pep useless...

Lab grade PBS sterile solutions are easy to get at multiple ph points (just need to know what ph your peptide is most stable at) but getting one that writes "for injection" is rare...

While I'm fairly confident if it's from a genuine lab supply it's probably safe for human use (it's used with live tissue experiments after all), I'm much more comfortable with human grade WFI based PBS,
 
If you're going to make your own, then do yourself a favor and make Phosphate Buffer Saline (only the type using Water for Injection) and add USP Benzyl Alcohol.

This is the same buffer solution used in pharma pens for Tirz, Sema, and rHGH to maintain ideal PH 7.2-7.4. Not only is this physiological pH so injections are comfortable, it keeps these compound far
more stable, with less degradation and aggregation.

UGL GLPs and rHGH almost never include pH control excipients, and end up acidic 5-6 pH after reconstitution with BAC. Acidity damages these proteins and can cause injection site reactions.

Most peptides do best at this pH, but not all. Some are more stable when in a slightly acidic solution, so check the specific compound. But for all GLPs and rHGH this buffer solution will give you better results.

This is the cheapest PBS with Water for Injection I've found. Shipping is high but it's still not bad, esp if you buy a few bottles at a time.

Reta can't be recon with saline water.

Fyi
 
pH of SSA T15 reconstituted in hospira bac water is around 5.95 according to my meter. It’s not perfectly calibrated but it’s a rough idea.

Solubility of peptides in Phosphate Buffered Saline is different than saline.

Saline is just salt (NaCl), which makes peptides aggregate and come out of solution.

PBS has salt as well, but also a mix of other ions that keep things balanced and neutral preventing aggregation.

It's interesting that in QSCs last months they started offering a variety of reconstitution solutions. I asked but he never specified which of the "non standard" ones were needed for which peptides.

yuuuup, missed the the boat, i was just being a "glutton",, ;)

It’s too late for Medex. It’s no longer in stock. And AMSCO is $8-9 a bottle if you can get around their medical credentials requirements.

Worth a try. Sometimes it's an empty request. See if you can put in the order on the website & pay.

Worked for me with CIAMedical. They emailed for credentials after I paid on the website. I said no and asked for a refund. They said OK. The pack landed.

(they no longer carry Hospira BAC)

I thought about trying that with AMSCO but I still have 35-40 bottles of Hospira. Before I pay $8-9 a bottle I’ll make my own. Some sites are selling a case of 25 for $300-400. Crazy prices.

Not too long ago they were $15 per bottle. Then Medex came along.

But yeah making it is so easy. It's not like setting up a whole home brewing station.
 
Okay I saw Medex is out but they still have Hospira Sodiun Chloride .9%. Is that adequate for peptide reconstitution? I can't find a straight answer.

PBS will absolutely destroy your NAD+ in days..
 
Over here in Aus if you go name brand like Hospira you can easily pay $32 per 30ml bottle of bac water.
I sooner pay my measly $4 for 1000mls of water for injecting in the bladders and then add BA.
Bac water should be the least complicated of issues.

Essentially no.

A few can be reconstituted without being damaged by it, BPC-157, TB-500, Selank, Semax, but usually only used if someone gets an injection site reaction. Even then you'd want the Bacteriostatic Sodium Chloride .9%

Hospira makes a .9% BA Sodium Chloride Bac Water.

I snagged a case off medex since they were out of normal bac water. Just in case it was usable lol.

Now im just looking to see what I can use it for... essentially im wondering if its usable for HGH reconstitution.
