What is Tesamorelin?
Tesamorelin is a stabilized analog of growth-hormone-releasing hormone studied for its reported effect on visceral adipose tissue - the fat surrounding internal organs - in metabolic research models.
Tesamorelin stimulates endogenous GH release like other GHRH analogs, with research focused specifically on visceral-fat endpoints rather than subcutaneous fat.
What is AOD 9604?
AOD 9604 is a modified fragment (residues 176-191) of human growth hormone, representing the region associated with fat metabolism. It is studied because it isolates the lipolytic portion of GH without the growth-signaling or glucose effects of the whole hormone.
AOD 9604 research focuses on stimulation of lipolysis (fat breakdown) and inhibition of lipogenesis without acting on the IGF-1 axis or blood glucose - the defining research feature.
Key research differences
The two are best understood by what each is studied for. Tesamorelin: Tesamorelin is studied for visceral fat specifically, distinguishing it from AOD 9604 (general lipolysis) and the GLP-1 peptides (appetite). AOD 9604: Unlike GLP-1 peptides that act on appetite, AOD 9604 isolates the fat-metabolism portion of GH and does not affect blood sugar - a distinct research mechanism.
How researchers choose between them
Because Tesamorelin and AOD 9604 both sit in the fat loss & weight management category, the choice is a research-design question: match the compound to the exact signal or endpoint your model targets, and in many protocols the two are studied in parallel or in sequence rather than as either/or. Whichever you select, compare on verified quality: both are third-party tested to a 99%+ purity target with a COA on request.

What is the difference between Tesamorelin and AOD 9604?
Tesamorelin is a GHRH analog studied for visceral-fat and metabolic research, while AOD 9604 is a growth-hormone fragment studied for lipolysis research without blood-sugar effects. Both sit in the metabolic research category. Both are research-use-only. Tesamorelin: Tesamorelin is studied for visceral fat specifically, distinguishing it from AOD 9604 (general lipolysis) and the GLP-1 peptides (appetite).
Can Tesamorelin and AOD 9604 be studied together?
Yes - within the same category they are often studied in parallel or sequence to compare or combine effects. Any combination work is laboratory research only. AOD 9604: Unlike GLP-1 peptides that act on appetite, AOD 9604 isolates the fat-metabolism portion of GH and does not affect blood sugar - a distinct research mechanism.
Which is better, Tesamorelin or AOD 9604?
Neither is universally "better" - the right choice depends on the research question. Match the compound to your model's target signal, and compare suppliers on verifiable third-party purity, not sticker price. Tesamorelin is a stabilized analog of growth-hormone-releasing hormone studied for its reported effect on visceral adipose tissue - the fat surrounding internal organs - in metabolic research models.
What sizes are Tesamorelin and AOD 9604 supplied in?
Tesamorelin is supplied in 5 mg and 10 mg research sizes and AOD 9604 in 5 mg and 10 mg, both as lyophilized (freeze-dried) powder in sealed vials that are reconstituted in the lab before use in a liquid research model.
Are Tesamorelin and AOD 9604 FDA approved?
No. The research-grade Tesamorelin and AOD 9604 supplied here are not FDA-approved drug products; they are sold strictly for laboratory and in-vitro research. Where an approved pharmaceutical form of either compound exists, it is a separate prescription product made to clinical standards. Research material is not for human or animal consumption.
