Would definitely order from them again.
My summary: bought from old Amo site (don’t ask which one, it used to be renamed routinely), pinning for months, got a teensy sting maybe three times - but that is likely as I didn’t let alcohol swab dry thoroughly; that soft “sting” is NOTHING like the wasp-like sting for HOURS after pinning GHK-Cu.
I asked to for a shipment from US-based warehouse and my box showed up within a few days. Found their communication customer service to be fast/efficient (better than the Apple item I just bought online - paid to get order by a specific date and had to beg customer service to delivery by the date promised - just so sick of these tech vendors).
Although I have a freezer full, I was keeping my eye on Amo because I lived through the days of US-based grey providers (yes, I know I paid an arm and a leg) just one day up and closing shop. I felt that with the goofus screwing us all over with tariffs that things were going to become dicey. So honestly, when AMO/BFF whatever they call themselves are back on line, I am going to get some more in storage.
