LuvionBio 回复2026-04-30Hi Katie,
Thanks for taking the time to leave a review. That said, I own the company and did email you you a detailed response which i will post here. I think there may be some confusion around the intent of cold-chain shipping. We guarentee stability, potency, and purity, not a cold arrival.
High level, we want to protect against large temperature swings that could actually damage peptides. As long as the lyophilized vials arrive in two days, the research (which you can verify online or with ai) indicates there is zero concern unless temps exceed 140°F Our cold chain shipping process has been tested extensivley, and the data is solid. During summer months we will switch to a foam with a better MKT and R-value, but still the risk to freeze dried powder is near zero.

Hi Katie,
Thanks so much for reaching out and for letting us know about your concern. I completely understand why you'd be worried seeing the ice packs arrive warm, but I want to put your mind at ease.
It's actually totally normal for the ice packs to melt during transit. The real purpose of our cold chain packaging is to prevent massive temperature spikes that could degrade the peptide quality, especially during the summer months when delivery trucks can reach up to 140 degrees in the back. We've done extensive stability testing on our current system, and I'm happy to report there has been zero decrease in purity or potency, so you can rest assured that the research you intend to conduct is fully protected. Lyophilized powder at ambient temperature is extremely stable, which is why your order is perfectly safe to use.
Now, if your peptides had been reconstituted and arrived warm, that would be a different story and you'd absolutely need to discard them. But in this case with the lyophilized powder, we are rock solid. To give you even more confidence, we've shipped the same way to our contract development and manufacturing organization in Germany for cell-based assays to evaluate potency and safety. That shipment was in transit for 12 days, and the testing confirmed zero degradation. We'll be publishing those reports shortly, which is really exciting. Those tests cost around $25,000 each and were conducted by Reaction Biology, a company that works with all major pharmaceutical companies, so the data is beyond reproach.
I hope this puts you at ease, and thank you so much for asking the question and for your continued support. We're always working to improve our packaging, and we'll soon be switching to higher-rated insulated packs and different ice packs to give our customers even more peace of mind.
If you have any other questions or concerns, please don't hesitate to reach out anytime.
Warmly,
CJ
CEO
