Nootropic peptides · ACTH-fragment analogue studied for brain and nerve effects.

Comes as: Community-reported freeze-dried powder vials, labelled 5 or 10 mg, Home-mixed nasal sprays.

Mixed with: Community reply: nasal saline, 10 mL for a 10 mg vial. No verified human injection-mixing protocol was found..

Common vial sizes: 5, 10 mg. Common water amounts: 10 mL.

  • A poster assumed 0.1 mL per spray. Actual pump output was not measured, so this is not a verified delivered dose.
  • A shared bottle or combined solution has no verified compatibility or microbial-safety data.
  • Russian finished nasal drops need no mixing; their historical storage instructions are recorded with those clinical-practice protocols.

Before mixing: No validated storage conditions or shelf life were found for unregulated powder vials. Finished-medicine instructions do not establish powder stability.

After mixing: No validated after-mixing shelf life was found. A saline recipe does not establish stability, preservation or microbial quality.
