How much weight loss does Tesamorelin cause?

In the LIPO-010 trial, Tesamorelin 2mg daily reduced visceral fat by ~18% after 26 weeks vs placebo. Individual results depend heavily on diet and baseline adiposity.

What is AOD-9604 used for?

AOD-9604 was developed and Phase 2/3 trialed as an anti-obesity agent. It was granted FDA Orphan Drug status. It is now primarily used as a research chemical for its selective lipolytic properties.

What is the dose of AOD-9604?

Research protocols typically use 250-500 mcg subcutaneously once daily, often in a fasted state before morning exercise. For research use only.

Does AOD-9604 cause hunger?

AOD-9604 does not stimulate ghrelin or appetite pathways. It may actually have mild appetite-suppressing properties. In contrast, GH released by Tesamorelin can transiently increase appetite.

Is Tesamorelin available as a research chemical?

Yes, Tesamorelin is available from research chemical vendors as a lyophilized peptide, though its FDA-approved form (Egrifta) requires a prescription. For research use only.

Can AOD-9604 be used with semaglutide?

Preclinical evidence supports combining GLP-1 agonists with lipolytic peptides like AOD-9604 for additive fat loss via complementary mechanisms. This combination is being studied informally in research communities.

Which is better for stubborn belly fat?

Tesamorelin is clinically superior for visceral (belly) fat specifically, given its FDA-approved trial data. AOD-9604 targets general lipolysis but may have some visceral fat preference via beta-3 receptor distribution.

AOD-9604 vs Tesamorelin: Dosing, Half-Life, Side Effects + Which to Choose (2026) | PeptiDex

Quick Verdict

Tesamorelin drives stronger fat loss via GH receptor activation (FDA-approved for lipodystrophy). AOD-9604 offers targeted lipolysis without GH receptor binding — ideal for subjects who need fat loss without GH-axis concerns.

Which one should you choose?

Tesamorelin produces substantially greater fat loss via powerful GH spikes; AOD-9604 offers a safer, gentler lipolytic effect without affecting blood sugar. Tesamorelin is FDA-approved for visceral fat and works by triggering massive GH release (activating the full GH receptor pathway). AOD-9604 is a GH fragment (177-191) that directly stimulates beta-3 adrenergic receptors in fat tissue — bypassing the growth receptor entirely. Choose Tesamorelin for aggressive visceral fat reduction. Choose AOD-9604 if you need fat loss without any GH-axis stimulation (e.g., active cancer concerns, blood sugar sensitivity).

Who Should Choose AOD-9604?

Choose AOD-9604 if you:

Want direct lipolysis without GH receptor stimulation
Are sensitive to blood sugar disruption from GH elevation
Are researching fat loss as an add-on to an existing GH protocol
Need a very mild, well-tolerated fat loss agent

Who Should Choose Tesamorelin?

Choose Tesamorelin if you:

Want the most aggressive visceral fat reduction available
Are comfortable with the full GHRH mechanism and GH stimulation
Are researching lipodystrophy or metabolic syndrome specifically
Want an FDA-approved mechanism with clinical trial data

Can you stack AOD-9604 + Tesamorelin?

These can be stacked carefully. AOD-9604 acts peripherally on fat cells; Tesamorelin acts centrally via the pituitary. The combination may produce additive fat loss effects. However, researchers should monitor IGF-1 and blood glucose when stacking any GH-axis peptide.

Frequently Asked Questions

No — this is AOD-9604's key advantage. It does not bind the GH receptor and does not raise IGF-1 or affect blood sugar, unlike full-length GH or GHRH analogs like Tesamorelin.
