SLU-PP-332 reconstitution woes!

Hey all, I'm in a bind. I got some SLU-PP-332 to inject, but didn't realize how tricky it is to mix. It seems like just using bacteriostatic water is a no-go because it's so hydrophobic.

I saw some videos suggesting using 0.5ml of DMSO followed by the same amount of BAC water. But everything I'm reading says injecting DMSO is super toxic at that concentration. I also found some info on using DMSO, then polysorbate 80, then buffered saline to dilute the DMSO to around 1%. Anyone have experience with this? I'm open to suggestions – and yes, feel free to point out my mistake, LOL.
 
Okay, so nobody else has tried this either, haha. Well, I kept digging, and found this:

Apparently, to dissolve really hydrophobic peptides, you can use a tiny bit of DMSO (like 30-50 μl at 100%), and then slowly drip that into a stirring buffered solution like PBS. They said if it gets cloudy, you've used too much peptide. Sonication may also assist.

They also had this handy rule of thumb:

* 0.1% DMSO: Usually safe for cells.
* 0.5% DMSO: Commonly used in cell culture without problems.
* 1% DMSO: Okay for some cells, but 0.5% is better.
* 5% DMSO: Has been used successfully in some cells.

Still researching...
 
That's precisely why I chose capsules. I'm unsure if they are more effective or not, but they definitely offer superior convenience.
 
I've seen people mention using 0.2mL or 0.3mL of DMSO with 2.3mL or 2.2mL of BAC water and claiming decent results. Maybe diluting the DMSO with more BAC could help?
 
Reconstituting peptides can certainly be tricky. While DMSO can be used, it's crucial to minimize exposure. The suggestions of using a small amount of DMSO followed by a buffer like PBS are reasonable. Ensure the final DMSO concentration is as low as possible, ideally below 0.5%, to minimize potential toxicity. Also, remember sterile technique is paramount.
 
Concerning pre-reconstituted peptides, I'd advise caution. I saw a discussion where someone received ipamorelin/cjc-1295 already mixed. It's best to inquire about shipping conditions, specifically if it was shipped cold. The stability of peptides in solution is significantly affected by temperature. If unsure, it's generally safer to reconstitute yourself. It sure would be nice to have a reference guide for proper handling of different peptides.
 
I've been wondering about the best reconstitution liquid. I've seen some mentions of acetic acid instead of bacteriostatic water, supposedly for longer shelf life, specifically for IGF peptides. Has anyone looked into this?
