AOD-9604 (Research Grade)

AOD-9604 is a 16-residue analog of the C-terminal 176-191 region of human growth hormone, with an added N-terminal tyrosine and a disulfide bridge that reproduces the loop geometry of the parent fragment. It isolates the lipid-metabolism-associated region of the hormone from its receptor-binding regions, which is why it is used as the fragment arm against full-length hGH in comparative metabolic research.

AOD-9604 specifications

Reference data researchers look up before ordering aod-9604. Every lot ships with documentation matching the batch number printed on the vial.

  • Class: hGH fragment 176-191 analog
  • Sequence length: 16 amino acids, disulfide-constrained
  • Molecular weight: approximately 1,815 g/mol
  • Storage: -20°C lyophilized, 2–8°C reconstituted

AOD-9604 purity testing and certificate of analysis

Each aod-9604 lot is released only after an independent purity panel. HPLC quantifies purity, LC-MS confirms molecular identity, and the lot-matched certificate is published so the number on your vial matches the report you download.

  • ≥99% HPLC purity specification
  • LC-MS mass confirmation on every batch
  • Endotoxin and sterility panel documentation
  • Lot-matched aod-9604 COA published on the certifications page

AOD-9604 reconstitution and BAC water ratios

AOD-9604 ships lyophilized. Reconstitute with bacteriostatic water containing 0.9% benzyl alcohol. The ratios below assume a standard U-100 insulin syringe.

  • 5mg vial + 2mL BAC water = 2.5mg per mL (10 units = 250mcg)
  • 10mg vial + 2mL BAC water = 5mg per mL (10 units = 500mcg)
  • Direct water down the vial wall onto the side of the cake, then swirl until clear
  • Never shake or vortex — a disulfide-bridged peptide scrambles at the air-liquid interface

Where to buy aod-9604

PX1 Research synthesizes and fills aod-9604 in a US cGMP-compliant facility rather than reselling imported material, so purity documentation traces back to the production lot. Multi-vial pricing steps down at 3, 5 and 10 vials, and subscription intervals are available on the product page.

Frequently asked questions

What is AOD-9604?

A 16-residue analog of the human growth hormone 176-191 fragment, with an added N-terminal tyrosine, supplied as a lyophilized research reference compound.

How is AOD-9604 different from the 176-191 fragment?

AOD-9604 adds an N-terminal tyrosine to the natural 176-191 sequence, which improves synthetic tractability and analytical detectability while preserving the disulfide-constrained loop.

How much bacteriostatic water for a 5mg AOD-9604 vial?

2mL yields 2.5mg per mL, so 10 units on a U-100 insulin syringe equals 250mcg of blend solution.

Is a certificate of analysis provided with aod-9604?

Yes. Every aod-9604 lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.

How should aod-9604 be stored?

Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
