Semaglutide vs AOD-9604
Semaglutide sits in metabolic / weight loss, while AOD-9604 sits in fat loss — so despite being mentioned together they are used for different things. A mixed vial also keeps differently: about 56 days for Semaglutide against 30 for AOD-9604. The table below sets out the differences. We give no dosing guidance.
Side by side, in plain English — what each one is, where they overlap and where they genuinely differ.

The differences that actually matter
They aren't really substitutes: Semaglutide sits in Metabolic / Weight Loss while AOD-9604 sits in Fat Loss. People usually pick between them because of a shared secondary effect rather than because they do the same job.
Once reconstituted, Semaglutide keeps noticeably longer than AOD-9604 (~56 days vs ~30 days), so vial waste is a real difference between the two.
Where they overlap: better glucose control.
Reported mainly for Semaglutide: suppressed appetite, weight loss.
Reported mainly for AOD-9604: fat oxidation, cartilage support.
What Semaglutide is
Semaglutide functions as a glucagon-like peptide-1 (GLP-1) receptor agonist, meaning it mimics the action of the naturally occurring incretin hormone GLP-1. Biochemically, it binds to and activates GLP-1 receptors located in various tissues, including the pancreas, brain, and gastrointestinal tract. In the pancreas, this activation promotes glucose-dependent insulin secretion and suppresses glucagon secretion, contributing to improved blood glucose regulation. In the brain, it influences satiety centers, leading to
What AOD-9604 is
AOD-9604 is a synthetic peptide derived from the C-terminal fragment of human growth hormone (hGH), specifically corresponding to amino acids 177-191. It was engineered to mimic the lipolytic (fat-mobilizing) effects of hGH while minimizing its impact on glucose metabolism and insulin-like growth factor-1 (IGF-1) levels. The peptide is thought to exert its effects primarily on adipose tissue by stimulating the breakdown of fat and inhibiting the formation of new fat. While the exact receptor mechanisms are still un
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — Semaglutide and AOD-9604 are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between Semaglutide and AOD-9604?
They aren't really substitutes: Semaglutide sits in Metabolic / Weight Loss while AOD-9604 sits in Fat Loss. People usually pick between them because of a shared secondary effect rather than because they do the same job.
Can you log Semaglutide and AOD-9604 in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, Semaglutide or AOD-9604?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
