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.
Regulatory interest in AOD-9604 increased after high-profile anti-doping cases involving peptide products. In some cases, the substance was supplied under alternative names or in compounded preparations, complicating traceability. Sports tribunals and anti-doping panels have discussed whether the peptide was explicitly banned at the time of use, leading to clarifications by the World Anti-Doping Agency. For consumers and researchers, the legal status can vary by jurisdiction, and products marketed as research chemicals may lack independent quality verification.
AOD-9604 is listed as a prohibited substance in sport by the World Anti-Doping Agency. It falls under the peptide hormones, growth factors, related substances, and mimetics class on the prohibited list. Anti-doping organizations treat its presence in an athlete's sample as an adverse finding unless a therapeutic use exemption applies. The prohibition reflects concerns about performance enhancement in competitive settings and the difficulty of distinguishing exogenous peptide use from endogenous hormone fragments.
Detection of AOD-9604 in biological samples relies on analytical techniques capable of distinguishing a small synthetic peptide from related endogenous sequences. Liquid chromatography coupled with tandem mass spectrometry is commonly used for confirmatory analysis. Sample preparation may involve immunoaffinity enrichment or solid-phase extraction to concentrate the peptide. Because the molecule is small and may be present at low concentrations, assay sensitivity and specificity are ongoing analytical challenges. Laboratories also validate methods against reference materials when available.

The two-star award was restored a year later in the 2009 Michelin Guide, as had been predicted by a number of Bosi's fellow chefs including Tom Aikens, Antonin Bonnet and Richard Corrigan. Sat Bains went a step further and said "I would love to see Claude Bosi regain his second star at Hibiscus and win his third in time. He's probably the best chef I know." The restaurant closed permanently in 2016, two days prior to the announcement of the 2017 Michelin Guide for UK and Ireland.

=== Nicole Craig === Nicole Craig (Sarah Parish) is the CEO of investment fund Mallon Mercer, and a major Pierpoint client. Despite being an outspoken feminist in public, she repeatedly engages in predatory sexual behavior toward junior bankers. In series 1, Nicole makes a drunken sexual advance on graduate Harper Stern following a client dinner. Harper initially maintains the relationship to protect her job but later deliberately antagonizes Nicole into severing ties with Pierpoint. In series 2, Robert, looking to make more outgoing calls, wins Nicole back as a Pierpoint client by being endearingly honest about feeling out of his depth at the job. The two connect over dinner, and Nicole masturbates him in the car on the way home. The two continue an illicit sexual relationship for months onward, with Robert projecting many of his unresolved issues with his late mother onto the domineering Nicole. Robert later learns from Harper that Nicole made an advance on her the previous year. Nicole later sexually assaults new hire Venetia Berens, who Robert left alone with Nicole during a client dinner that went sideways. Venetia’s attempt to report the incident is suppressed by Pierpoint management. Robert tries to cut ties with Nicole afterwards, but she reestablishes her control over him after bailing him out when he is arrested for cocaine possession. In series 3, Robert and Nicole are still involved; Robert spends a night with her, only to suddenly find her dead the next morning.

A study by Kim et al. investigated the nutritional value of S. mutilans hoping to extend the application of this species from traditional medicine only. Nutritional analysis on this species found that it is high in crude protein (around 55%) and fat (around 26-30%). Essential amino acids were present, with lysine being the most common (around 3.5% of all essential amino acids), and glutamic acid being the most common nonessential amino acid present in the centipede (around 7% of all nonessential amino acids). Unsaturated fatty acids were also present, with oleic acid being the most common (around 41-48%). Mercury was found, but the concentration was below food safety limits. Pathogenic microorganisms were not found in the centipede samples. From these findings, the researchers suggested that S. mutilans has the potential to be a medicine and food ingredient.
=== Fructose metabolism === Fructose must undergo certain extra steps in order to enter the glycolysis pathway. Enzymes located in certain tissues can add a phosphate group to fructose. This phosphorylation creates fructose-6-phosphate, an intermediate in the glycolysis pathway that can be broken down directly in those tissues. This pathway occurs in the muscles, adipose tissue, and kidney. In the liver, enzymes produce fructose-1-phosphate, which enters the glycolysis pathway and is later cleaved into glyceraldehyde and dihydroxyacetone phosphate.
=== Continued hostilities (30 May – present) === On 30 May 2026, five TTP militants were killed in combat in Darra Adamkhel in a military operation and in the same operation, eight more insurgents including two Afghan Tariq Gidar group affiliates were killed, the following day. Insurgents attacked a police station in Wana. On 1 June 2026, four TTP militants were killed during an attempted VBIED suicide attack on a military post near Miranshah. Two civilians were injured in a mortar attack in Salarzai Tehsil. Pakistani forces start "Operation Iron Fist-3" in Miranshah. From 1-3 June 2026, Pakistani forces cleared the villages of Nadeem Kot and Khuzai from TTP control, killing eight insurgents and wounding 14 to 16 under Operation Iron Fist-3 in Miranshah. On 3 June 2026, allegedly Pakistan-linked hacking group "SideCopy" conducted a cyberattack against Taliban Finance Ministry, provincial financial and revenue offices, Pashto-speaking officials and local government employees. On 4 June 2026, ISPR claimed that Pakistani forces had killed two TTP militants in Dera Ismail Khan District and two more in Sheikh Banda area of Mohmand District. Pakistani forces began the second phase of Operation Iron Fist-3 in Miranshah. Taliban and Pakistan held an informal talk in Termez, mediated by Uzbekistan. On 5 June 2026, Pakistan reiterated that it has the "right" to strike militant targets inside Afghanistan. Two sons of a tribal leader were killed in Wana. On 6 June 2026, ISPR stated that Pakistani forces had killed 27 TTP insurgents in and around Miranshah, over the last three days.
This can be the case, for example, if one kidney has already become a non-functioning shrunken kidney due to urinary retention and the second suddenly swells acutely due to urinary retention (hydronephrosis) and is damaged ("large kidney-small kidney syndrome") or if hyperthyroidism is treated and the glomerular filtration rate is suddenly reduced as a result.

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.
Because it is a fragment rather than full growth hormone, it is generally described as lacking growth-promoting effects. Some studies suggest it may influence fat metabolism without the same systemic growth effects, though evidence is limited.
Human trials have measured body weight, fat mass, lean mass, lipid levels, and adverse events. Most have been small or short-term, so conclusions about long-term outcomes are limited.
Yes, the World Anti-Doping Agency classifies AOD-9604 as a prohibited peptide hormone and related substance. Its use by athletes is banned under the relevant anti-doping code.
