Question 1

Where to Buy AOD-9604 for Research: Sourcing and Quality Checklist

Accepted Answer

AOD-9604 is available from research peptide suppliers as a lyophilized powder for in vitro laboratory use. Spartan Peptides carries AOD-9604 with HPLC-verified purity and mass spectrometry sequence confirmation. Researchers sourcing this compound should verify third-party testing documentation before beginning any laboratory protocol.

Question 2

What Is AOD-9604?

Accepted Answer

AOD-9604 is a synthetic peptide fragment derived from the C-terminal region of human growth hormone (hGH), specifically residues 177-191. It was originally studied by researchers at Monash University in Melbourne as a potential metabolic research tool. The fragment was of interest because it appeared to retain lipolytic signaling properties observed in full-length GH models without some of the mitogenic effects associated with the intact hormone. Early published research by Heffernan et al. examined the compound's activity in adipose tissue models. AOD-9604 reached Phase 3 clinical trials for obesity before the program was discontinued. Today it's sold exclusively as a research compound.

Question 3

What to Look for When Sourcing AOD-9604

Accepted Answer

Not all peptide suppliers maintain equivalent quality controls. For AOD-9604 specifically, researchers should confirm: HPLC purity greater than 98% (the standard for research-grade material), mass spectrometry confirming the correct molecular weight and sequence, a third-party COA issued by an independent analytical lab (not the supplier's own facility), sterility testing (important for any compound used in cell culture models), and lot-specific documentation (each batch should have its own COA, not a generic reference document).

Question 4

Storage Requirements After Purchase

Accepted Answer

AOD-9604 in lyophilized form is stable at room temperature for short periods but should be stored at minus 20 degrees Celsius for long-term research use. Avoid repeated freeze-thaw cycles. Once reconstituted with bacteriostatic water, the solution should be stored at 4 degrees Celsius and used within established windows documented in the supplier's handling protocols.

Question 5

Why Sourcing Quality Matters for Research Validity

Accepted Answer

Research outcomes depend on compound identity and purity. An impure peptide preparation introduces confounding variables that can invalidate in vitro results. The research community has documented cases where inconsistent findings across labs traced back to differences in compound quality rather than experimental design. For AOD-9604 research, this is especially relevant given the compound's modest receptor binding affinity, where impurities can disproportionately affect signal-to-noise in assay systems. Spartan Peptides publishes lot-specific COAs for AOD-9604 and all compounds in the catalog. Independent analytical data is available before purchase for researchers who need to document sourcing in their experimental records.
