@WisGal64 That's interesting about Southern Aminos directing traffic to Coastal Peptides at one point. Makes you wonder how many of these companies are connected behind the scenes or sharing infrastructure. Out of curiosity, what's your go-to vendor these days?
Glow and flawless are sister companies from what I understand. Not sure if there is an affiliation with southern. When I first started receiving emails from Southern amino’s a few months back, when I clicked on their advertisements, it navigated me to coastal peptides found that one interesting. It no longer does that.
Good results so far and shipping was fast. Just my preference which may seem petty but I prefer a plastic label than a paper. I like to reuse my labels, after filtering into a pen cartridge, so I have the batch and all the info on my pen from the lab.
