Acetic water / Acetic Acid is a research water that has a lower PH level as apposed to bacteriostatic water.Acetic Acid water is used in a research environment that helps "clear up" and "un-clump" certain Peptides yet mandatory fully for others based on the Peptides amino chain, sensitivity and purity.Peptides with much higher purity and or sensitivity within the amino acid chain can cause a slight cloudy appearance from not being totally broken down as can Peptides not reconstituted properly with water being "blasting" into the vial with high pressure and or shaking the reconstituted product roughly can also cause "cloudiness".Store in a cool, dry place away from light. Once reconstituted, please refrigerate. For long term storage, freezing at -20°C is recommended to maintain integrity.All products are shipped in lyphollized or powder form and must be reconstituted to a liquid for research and testing.We do not provide dosing instructions or research guidance.
