{"id":210,"count":9,"description":"Nasal Sprays groups peptide spray formulations that are already dissolved and filled at a defined concentration \u2013 usually in a 10 ml container. The methodological difference from a lyophilisate in a vial is that no reconstitution step takes place: concentration and solvent composition are fixed at the point of manufacture, and the quantity delivered results from the calibrated pump stroke rather than from withdrawal by syringe. This reduces transfer errors but shifts control over the formulation entirely to the production side. Substances offered in this form include Selank, DSIP, BPC-157, NAD+ and Ipamorelin. With dissolved formulations, storage is the decisive factor: peptides in aqueous solution are more sensitive to temperature, light and oxidation than a dry lyophilisate, so cool, light-protected storage and a documented shelf life after opening belong in the laboratory protocol. The opening date and storage conditions should be recorded, since both influence the validity of later measurements. The spray format is purely a laboratory formulation and in no way a recommendation for use. Each batch is tested in-house by HPLC and UV\/Vis spectroscopy, and the batch certificate of analysis is viewable before purchase \u2013 the COA Guide explains how to read it. <strong>For research use only. Not for use in or on the human body.<\/strong>","link":"https:\/\/peptelia.com\/en\/product-category\/nasal-sprays\/","name":"Nasal Sprays","slug":"nasal-sprays","taxonomy":"product_cat","parent":0,"meta":[],"menu_order":0,"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Peptid-Nasensprays kaufen \u2013 mit COA | Pept\u00e9lia<\/title>\n<meta name=\"description\" content=\"Peptid-Nasensprays als Forschungsformulierungen: Selank, BPC-157, DSIP, NAD+, Oxytocin und mehr \u2013 mit COA je Charge.
