All EONA batches are tested to this value; the result is documented in the batch-specific COA, which can be downloaded before ordering. In addition, an independent academic counter-check confirms purity and identity by mass spectrometry.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between a commercial manufacturer's COA and an independent academic counter-check?\u003c\/h3\u003e\n\u003cp\u003eA commercial manufacturer's COA is created by the producing laboratory and tests purity and identity as part of its own quality assurance. An independent academic counter-check means that a second analytical instance, separate from the manufacturer, re-measures the same batch. EONA combines both procedures: commercial batch COA plus academic counter-check. The procedure is described on the \u003ca href=\"\/en\/pages\/verifizierung\"\u003eVerification: two-stage procedure\u003c\/a\u003e page.\u003c\/p\u003e\n\n\u003ch3\u003eCan Semax be ordered in Germany for research purposes, and what is the legal classification of Selank and DSIP?\u003c\/h3\u003e\n\u003cp\u003eSemax and Selank are not approved as medicinal products in Germany and are not subject to the BtMG or the NpSG; as research substances, they can be obtained by verified research institutions and qualified private individuals. DSIP is legally classified analogously as an unapproved research substance but is not yet available for purchase in the EONA product range. EONA sells exclusively for research purposes, not for human use. When sourcing from the EU warehouse, the customs risk of a third-country import is eliminated. For specific legal questions, examination by a lawyer is recommended.\u003c\/p\u003e\n\n\u003ch3\u003eHow do Semax, Selank, and DSIP differ biochemically and in their preclinical research direction?\u003c\/h3\u003e\n\u003cp\u003eSemax is a synthetic heptapeptide, derived from the ACTH(4-10) fragment, and is investigated in preclinical research in the context of dopaminergic and serotonergic signaling pathways. Selank is a tuftsin analog (octapeptide) and is the subject of preclinical studies on GABAergic and serotonergic regulatory circuits. DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide of neuroendocrine origin and is investigated in preclinical research in the context of sleep-wake regulation. In preclinical literature, Semax and Selank are sometimes considered together in the context of serotonergic signaling pathways, while DSIP is assigned to the neuroendocrine axis. All three substances are available as lyophilized solids. DSIP is not yet available for purchase in the EONA product range.\u003c\/p\u003e\n\n\u003ch3\u003eWhat storage conditions apply to lyophilized neuropeptides as research material?\u003c\/h3\u003e\n\u003cp\u003eLyophilized research peptides should be stored cool (2-8 °C), dry, and protected from light. Unopened vials are typically stable for months under these conditions; exact details can be found in the respective COA and product data sheet. Storage at -20 °C generally further extends stability. EONA explicitly does not provide reconstitution or application instructions.\u003c\/p\u003e\n\n\u003ch3\u003eWhy is a batch-specific COA preferable to a general product specification?\u003c\/h3\u003e\n\u003cp\u003eA general product specification describes the target nominal value, not the actual measured result of the batch supplied. A batch-specific COA proves the measured purity value and the mass spectrometrically confirmed identity of exactly the batch that the researcher receives. This makes the quality of the substance directly traceable for the respective experiment. EONA provides the COA per batch; the academic counter-check forms the second verification stage.
