Has anyone here looked into using an additional third-party lab for compound identification and sterility testing of the gear? I trust Jano and have used his services in the past, and plan to keep doing so, but I think it could be beneficial to have another independent lab to verify the compounds and ensure sterility.

All due respect to Tracy, as I believe his product is solid, but in the spirit of harm reduction, I think running additional tests would be valuable. I’m new here and want to contribute to the community, so I’m curious if this has already been discussed or if anyone has experience with this. Any thoughts?
 
smart people… probably just buying peptides from China and te selling… idk how some claim to make them here… isn’t it illegal? Rick Collin’s will deff get them out the pinch lol
Not illegal, some of the (larger) compounding pharmacies do it, usually minus HGH, but no matter what any of them do, Rick would definitely get them out!

It’s not the first time someone has raised the idea of using other labs more, but the other labs always end up getting caught engaging in some sort of fuckery and we all go back to Jano.
 
Could you please confirm the material identity on batches moving forward?




[Because XIANGYI is the manufacturer of the serum stopper, we can customize the color of the stopper, such as red serum stopper, gray serum stopper, pink serum stopper, Serum Stoppers in Red Natural Rubber, Gray Butyl, and Silicone, and we can customize the size of the serum stopper, such serum stopper with Straight Sided Plugs, 11mm, 13mm, and 20mm, serum bottle stoppers with Blow back finish, 20mm and 30mm.]
Silicone is not good and it's useless anyway without a PTFE coating.

Butyl stopper is fine for not super long term storage.
 
Just wondering cause normally ships in the us… now from china so confused a little. Thanks
It’s an international order, right? If you enter your tracking number into parcelsapp.com you might be provided a different USPS tracking number called Last Mile Tracking. If the only number you were provided is the USPS # you can manually add it to Informed Delivery.

I have used silicone stoppers for years and have never detected a problem with them deteriorating. That is not to say it’s not happening, but I have not Visually seen any deterioration. When googling it, I don’t see anything about BA or BB causing any issues. I am not saying it does not happen somehow but I can’t seem to find documentation saying not to use it.
 
Benzyl Benzoate turns silicone to goo and causes chemicals to leech into the solution making it unsuitable.

PTFE coated bromo or chloro butyl rubber is the ultimate non-reactive stopper, especially for long term storage.

Was interested in Tracy's thoughts. I had thought they were common for lyo vials.

To Ghoul's point. See benzol and benzyl group entries above.

Shows BB in the worst category of silicone compatibility here as well:
