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.
