@researchcat yeah, check out @southernaminos they still have SS-31, Randy said so in his last email.

The China sellers on Amazon have dropped out for the most part. My last purchase was from a HK seller. Search amazon for Biomed Solution Sterile Syringe Filter.

I'll keep that in mind, thanks. I do research almost immediately out of the fridge. I also misspoke and meant to say the needle I use to transfer the peptides from the vial to the pen cartridge is a 25 gauge.

@PeptideEd Yeah, but you can easily simplify this by figuring out where you want to get to and backing into it. If you want to get to 1mg, you just reconstitute with the same 1ml, round to 11, and at 91 units you’re getting ~1.032 mg per shot. I tend to be very precise in doing my recon math, but at the same time, when I am arguing with friends over whether they should research 5 units or 6 units, we’ve gone overboard and should either add more bac water(if possible) or worry about it less. (If a difference of 1 unit is going to make you sick or otherwise impact our research, imo, we should definitely be taking a step back to reconsider our process.) The good thing about this is that you can adjust the math a few different ways to get as precise as you want to if you don’t mind a little more work on the front end.

Randy, thank you for the feedback and direction, much appreciated!

Thank you, both!

Thanks. I looked again on Amazon but still could only find 30g or 32g luer-lock needles. The only 31g I could find were the needle/syringe combos. Strange. Oh well, I decided to buy the 32g 4mm.

The sodium from each most likely forms a bond then. Thanks!

New to this grey market but not to Healthcare. Peptides are very much part of the future of medicine imo and I'd love to see them more accessible to more people. Will post more of what I think are good deals as I come across them.

Hi, I'm looking for a source for generic, economical 0.5" core resin ribbons and small holographic label rolls with a 1" core for TTR printers. Really hoping someone here has experience with this. I would like to make some labels for my 3ml+ vials and syringe barrels
