Nasal sprays

Nasal sprays hold a ready-made solution of the research material in a 10 ml spray bottle, with the total amount stated on the label and the product page, so there is no powder to dissolve. The range covers neuropeptides such as Semax and Selank, tissue-research peptides such as BPC-157, melanocortin analogues, bioregulators, NAD+ and a retatrutide spray. A solution keeps for a shorter time than lyophilized powder, so keep each bottle closed, refrigerated and away from light, and choose the vial form when you need your own concentration or longer storage. For laboratory research use only.
