Nice watch

@ResearchCat what!!

Jeff’s hand modeling gig, and why he wore gloves for this clip. [image: 1793591335574-img_7400.png]

I bought a thymosin alpha 1 kit of 10 from Lily peptide. It had no date on it. And it had butterflies on the cap. I’m sure they got it from someone else because it didn’t look like the other kits of different peptides that I ordered in the same shipment . I reconstituted it with bacteriostatic water and it was very clumpy and gelled. I contacted her about it and she told me to add acetic acid. It didn’t make sense to me that the peptide would be good just because I use acetic acid. She told me to reconstitute another file and see how that one turned out. That one was cloudy as well. I never did try the acetic acid cause I don’t trust the peptides in the first place. I’m glad I came across your video verifying what I felt. Thank you.

There was a wonderful 10min video that was once on YouTube but was deleted due to Eli Lilly. It was titled "How to Reconstitute Retatrutide | Step-by-Step Guide to Filtering Into a Pen Cartridge" (Peptide Critic, Nov 11, 2025, 10:05) https://www.youtube.com/watch?v=Bdh3NTir03w It was a wonderful video and I was very sad to see that the whole channel was wiped from YouTube. Can you please re-upload it here?

That’s a whole lot of effort to be a complete piece of garbage. Stick with the vendors who have everything to lose if they did this

@OscarMc This may not answer your question, but... I always go with my preferred combination of BAC/saline. Some people want more bac, some want more saline for less burn, etc. No matter what, I use a nasal spray calculator to see how much of each peptide I'm getting per spray. It's usually not perfect for me, but it works

Those graphics were state of the art in 2001. the video actually went viral back then

Yeah, I missed the demo because I was watching Randy play some awesome guitar. Your spread needs your black pen and Black Sabbath album cover to go with those black gloves.

Good lord. Even Jano tested the theory that you have to be gentle with the peps. That was proven bunk. Sure, you don't pretend it's a morocco, but you can really be quite aggressive to get the pep dissolved. Peps that tend to have a history of gelling, I would be a gentle with. That being said, it's an easy print (thanks for letting me know it's on makerlab,have it going in the print lab) and will use for some like Cagri or ARA. No supports needed, always a win.

@PeptideCritic Randy, will you ask Jeff to do a video spotlighting the V3 Ultra. Pretty, pretty please

@alwayslooking documentary work for ngo's

@Shifted some people wont and this tutorial is for them. we have tutorials for with and without filtering.

Perfect! Sent that to some friends.

@Showme24 bigger hole on the needle less resistance.
