I've tested this source across plenty of different peptides, even some of the trickier ones that usually cause headaches. It has worked without any issues at all for me so far. The main practical complaint centers on their glass vials, which stand high but sit on a narrow bottom, making them tip and slide around if touched and possibly tumble from a countertop. To be fair the alternative option also performed fine in my experience, though it costs more, proves tougher to locate, comes from large drug firms that I view negatively, and uses plastic containers that I prefer to avoid.
Has anyone found any peptides that this water will not work for? I keep seeing people state that they have a certain amount of another brand in reserve or just in case or for more delicate peptides, but does anyone have experience with this brand failing to reconstitute?
