How to reconstitute AOD-9604: mixing and storage

A growth-hormone fragment whose largest obesity trial failed to show meaningful weight loss.

Also called: AOD9604, Tyr-hGH177-191, LAT8881, LAT-8881, HGH fragment 176-191.

Fat-loss peptides · Modified C-terminal growth-hormone fragment.

Comes as: Community: lyophilized powder vials for injection., Oral capsules, tablets and troches are described in FDA’s review of marketed products..

Mixed with: Bacteriostatic water is reported. Some posts discuss dilute acetic acid; no home-mixing method is clinically validated..

Common vial sizes: 5 mg. Common water amounts: 2, 3 mL.

  • Community handling only: 5 mg vials with 2 or 3 mL water are reported, not a validated formulation.
  • Users report gelling. Adding acid or more water does not establish purity, sterility or stability.
  • Do not equate an opened diluent’s discard date with stability of a mixed peptide.
  • Sterility, formulation and storage conditions matter; oral trial safety does not validate home-prepared injections.

Before mixing: Forum users discuss refrigerating powder. There is no approved consumer-product storage label.

After mixing: Advice conflicts, including room temperature and refrigeration. No validated home-mixed shelf life was found.
