lipolysis raises a handful of sensible questions. This page answers them in order, starting with the fundamentals and moving to applications.
Reviewed 2026-07-16. Anything still debated is marked as such rather than presented as settled.
The peptide is frequently described as a growth hormone fragment, although it is chemically distinct from full-length hGH. AOD-9604 contains 16 amino acids and includes two cysteine residues that can form an intramolecular disulfide bond. In solution, this structural feature can influence folding, aggregation, and stability. Published descriptions sometimes call it hGH 176-191 or AOD9604, with spacing and capitalization varying. Such naming differences can complicate literature searches, database entries, and product verification.
Researchers have studied the fragment in cell and animal models to understand its metabolic actions. Some experiments report effects on fat breakdown and fat storage pathways, but the underlying mechanism remains incompletely defined. AOD-9604 does not appear to stimulate the same broad growth hormone receptor signaling as full-length hGH. Whether its observed activities arise from direct receptor interactions or downstream metabolic changes is an open question. Results from different assays are not always consistent.
Proposed mechanism focuses on lipolysis, the breakdown of stored triglycerides into free fatty acids and glycerol. AOD-9604 is thought to act on adipose tissue without stimulating appetite or affecting blood sugar in the same way as growth hormone. Laboratory studies report increased fat oxidation in some models. The precise receptor interactions and signaling pathways remain incompletely characterized. Researchers have proposed that the peptide may influence fat mobilization through pathways distinct from the full hormone.
Research has examined whether the peptide affects fat mass independently of growth hormone's other actions. Early animal studies suggested reductions in body fat, but species differences and small sample sizes limit interpretation. Human studies have generally been short and have not consistently shown large effects. Some trials measured body composition, lipid profiles, and safety parameters, but the overall picture is one of suggestive yet inconclusive metabolic activity. Findings vary across study populations and protocols.
A central uncertainty is whether observed metabolic changes translate into meaningful clinical benefits. Study designs vary in dose, duration, and participant characteristics, making comparisons difficult. Independent replication is limited, and the field lacks consensus on optimal endpoints or treatment duration. Ongoing or future studies may clarify mechanism and effect size, but current evidence does not establish a clear therapeutic role. Researchers often call for larger, longer, and better-controlled trials, while questions remain about which patient groups might respond.

Development of AOD-9604 began in the 1990s as scientists sought to isolate metabolic effects of growth hormone without its growth-promoting actions. Early laboratory work focused on fat cells and animal models. Several human trials followed, examining changes in body composition and fat mass. Results have been mixed, and the peptide has not progressed to widespread clinical approval. Interest continues in research settings, particularly regarding its mechanism and potential metabolic targets.
Regulatory status varies by country. In the United States, AOD-9604 is not approved as a prescription drug. It is sometimes sold as a research chemical or dietary supplement, though such marketing may fall outside legal frameworks. The World Anti-Doping Agency prohibits its use in sport. Researchers must obtain it through legitimate suppliers and follow institutional rules. Its legal classification continues to evolve as authorities increasingly assess peptide products more broadly.
AOD-9604 is a synthetic peptide whose sequence matches the C-terminal fragment of human growth hormone, specifically residues 176 through 191. This region differs from the full hormone in its receptor interactions. The peptide is not a growth hormone secretagogue and does not bind the growth hormone receptor in the same manner. Researchers have examined it for effects on lipid metabolism, but its exact pharmacological profile remains an active area of study.
AOD-9604 is a synthetic peptide whose structure corresponds to a C-terminal segment of human growth hormone. It is often described as hGH fragment 176-191, a 16-amino-acid sequence. The peptide was designed to isolate a region of hGH associated with fat metabolism while avoiding the full hormone's growth-promoting actions. Laboratory and commercial materials typically present it as a lyophilized powder for research use. Its identity is defined by amino acid sequence, not by a single brand.
The fragment includes residues that can form an internal disulfide bond between two cysteine positions. This structural feature can influence how the peptide folds and how stable it is in solution. AOD-9604 differs from full-length hGH in size and receptor interactions; it does not contain the entire growth hormone sequence. Published descriptions sometimes use slightly different residue numbering, so sequence information should be checked against primary sources. The molecule is small compared with intact hGH, which affects analytical detection and purification approaches.
Interest in AOD-9604 arose from attempts to separate metabolic effects from growth effects attributed to hGH. Early work explored whether the fragment could influence lipolysis or fat oxidation without promoting growth. Those questions remain partly unresolved because human data are limited and results have varied across studies. The peptide is not a hormone replacement for hGH and is not equivalent to hGH in clinical use. Its research history includes both laboratory studies and commercial marketing claims that are not the same as regulatory approval.
== History == Founded in 1972, the company was originally known as Bio Medical Data, Inc. until the early 1980s, when it changed its name to Doctor's Data. It was originally owned by Miller Pharmacal, which was founded by John J. Miller, former research chemist for J.B. Roerig, which was purchased in 1953 by Pfizer. Miller died in 1977, and three owners took control of the company with Ted Lueken as president.
In 2007, videos were shared on YouTube of alleged salvia users laughing uncontrollably, apparently unable to perform simple tasks or to communicate. In an interview published in the San Francisco Chronicle in June 2007, Daniel Siebert said that the videos "make salvia look like some horrible drug that makes people nuts and dangerous ..." and that it stops people from realizing "there are sensible ways to use something like this." Waco Representative Charles Anderson (R), who is sponsoring one of several bills to ban salvia in Texas, told colleagues at a legislative hearing about a video that depicts a salvia user behind the wheel of a car. "What we really worry about, is youngsters doing this and then getting in a vehicle or getting on a motorcycle or jumping in a pool somewhere." Michigan Representative Michael Sak (D) submitted a bill which proposed Schedule I classification of Salvia divinorum and salvinorin A. He said that if people had questions about the deleterious effects of salvia, they should go on YouTube to watch the videos. A reporter questioned Sak as to whether he had ever seen a "Girls Gone Wild" video, and whether that would incite him to make alcohol illegal (Sak replied that he hadn't yet had a chance to review the material).
== History == The first pharmacokinetic model described in the scientific literature was in fact a PBPK model. It led, however, to computations intractable at that time. The focus shifted then to simpler models, for which analytical solutions could be obtained (such solutions were sums of exponential terms, which led to further simplifications.) The availability of computers and numerical integration algorithms marked a renewed interest in physiological models in the early 1970s. For substances with complex kinetics, or when inter-species extrapolations were required, simple models were insufficient and research continued on physiological models. By 2010, hundreds of scientific publications had described and used PBPK models, and at least two private companies have based their business on their expertise in this area.

Supermarket News ranked 7-Eleven's North American operations No. 11 in the 2007 "Top 75 North American Food Retailers", based on the 2006 fiscal year estimated sales of US$15.0 billion. Based on the 2005 revenue, 7-Eleven is the 24th largest retailer in the United States. As of 2013, 8,144 7-Eleven franchised units exist across the United States. Franchise fees range between US$10,000 – $1,000,000 and the ongoing royalty rate varies. 7-Eleven America has its headquarters in the Cypress Waters development in Irving, Texas. Small-size Slurpees are free on "7-Eleven Day", on July 11. This holiday first became widely celebrated on July 11, 2008, when first discovered by J. Brabank and C. Johnson. One exception is 2020, when the COVID-19 pandemic caused that year's cancellation. 7 Rewards members got a free medium Slurpee in their app instead. 7-Eleven Stores of Oklahoma operated independently beginning in 1953 under an agreement with the Brown family. As part of this franchise agreement, 7-Elevens in Oklahoma bore slight differences to stores elsewhere: for instance, products such as Big Bite hot dogs were not sold there, the Slurpee was branded as the "Icy Drink", and Oklahoma stores operated their own loyalty program called "Thx!", which did not intersect with the national 7Rewards system. On March 2, 2020, 7-Eleven, Inc. announced it had officially closed on the acquisition of over 100 of these independently operated 7-Eleven stores in Oklahoma. All of these 100 stores were in the greater Oklahoma City metropolitan area.
== History == The dish is named after one of the members of the Stroganov family, a Russian noble family. It has been debated whether it is named after the diplomat Pavel Stroganov or the politician Alexander Stroganov. According to legend, while stationed in Siberia, Pavel Stroganov's chef found the beef to be frozen so solid that it could only be cut into small strips. Another legend attributes its invention to French cooks working for the family, but several researchers point out that the recipe is a refined version of older Russian dishes. In Russian, the dish is called Бефстро́ганов, from the French bœuf Stroganoff.
== Measurement == Molar masses are almost never measured directly. They may be calculated from standard atomic masses, and are often listed in chemical catalogues and on safety data sheets (SDS). Molar masses typically vary between:

=== Compounds === Vacuoles in the tuber of S. affinis are rich in stachyose. Stachyose is a tetrasaccharide, consisting of galactose, glucose and fructose. Stachyose is evaluated to be about 230 mg/kg in dry tubers.
=== Glycolysis === Glycolysis is the process of breaking down a glucose molecule into two pyruvate molecules, while storing energy released during this process as adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide (NADH). Nearly all organisms that break down glucose utilize glycolysis. Glucose regulation and product use are the primary categories in which these pathways differ between organisms. In some tissues and organisms, glycolysis is the sole method of energy production. This pathway is common to both anaerobic and aerobic respiration. Glycolysis consists of ten steps, split into two phases. During the first phase, it requires the breakdown of two ATP molecules. During the second phase, chemical energy from the intermediates is transferred into ATP and NADH. The breakdown of one molecule of glucose results in two molecules of pyruvate, which can be further oxidized to access more energy in later processes. Glycolysis can be regulated at different steps of the process through feedback regulation. The step that is regulated the most is the third step. This regulation is to ensure that the body is not over-producing pyruvate molecules. The regulation also allows for the storage of glucose molecules into fatty acids. There are various enzymes that are used throughout glycolysis. The enzymes upregulate, downregulate, and feedback regulate the process.

No, it is a synthetic peptide fragment corresponding to a small portion of hGH. It is not the full 191-amino-acid hormone and does not reproduce all of hGH's effects.
It is commonly described as a 16-amino-acid peptide based on residues 176-191 of human growth hormone. Some sources vary in notation, so checking the stated sequence is useful.
It is not typically described as a standalone natural hormone. The sequence is derived from the C-terminal region of human growth hormone, but the synthetic peptide is a laboratory-made construct.
It is proposed to promote lipolysis in fat tissue, the breakdown of stored fat into fatty acids and glycerol. The detailed receptor and signaling mechanisms are not fully established.
