Everything below concerns anti-doping. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2026-03-10. Where a claim depends on a specific study, the study is described rather than over-claimed.
Regulatory bodies have taken different approaches to AOD-9604. It is not approved as a prescription medicine by major agencies such as the U.S. Food and Drug Administration or the European Medicines Agency. In sport, the World Anti-Doping Agency prohibits peptide hormones, growth factors, and related substances, and AOD-9604 has been treated as a prohibited substance. These regulatory decisions reflect concerns about safety, efficacy, and potential misuse rather than proof of benefit.
Research on AOD-9604 also examines how the peptide is measured in biological samples. Analytical methods may include liquid chromatography coupled with mass spectrometry, immunoassays, or both. Detection can be challenging because the peptide is small and may be present at low concentrations. Published methods vary in sensitivity and specificity, so comparative interpretation requires attention to validation details. The presence of related hGH fragments can complicate identification in some matrices.
AOD-9604 has been investigated mainly in the context of body fat and metabolic endpoints. Some early animal and small human studies reported changes in fat mass or lipid markers, but findings were not uniform. Larger, well-controlled trials that would establish efficacy are lacking in the public literature. As a result, claims about weight loss or metabolic benefit remain investigational rather than established. The distinction between a research finding and a proven clinical outcome is central to discussing this peptide.
In the scientific literature, AOD-9604 appears in reviews of growth hormone fragments and in discussions of peptide-based metabolic research. Some sources distinguish it from growth hormone itself, while others group it with compounds marketed for weight management. The evidence base is small compared with approved obesity medications. Questions about long-term efficacy and clinical relevance remain open, and independent replication of key findings is limited. Most published reports are early-stage and exploratory.
AOD-9604 is a synthetic peptide modeled on the C-terminal region of human growth hormone. It is often described as hGH fragment 176-191. Research interest arose because it was designed to isolate possible effects on fat metabolism from other actions of growth hormone. It is not a full growth hormone molecule. Its development history includes early laboratory and animal studies followed by human trials. The peptide has been examined in laboratory, animal, and limited human studies.
The compound has been studied as a potential treatment for obesity and related metabolic conditions. Published trials have examined changes in body weight, fat mass, and safety markers over limited durations. Results have been mixed or modest, and no large-scale outcome trials are established. Regulatory agencies in several countries have not approved it as a therapeutic drug. Some commercial products have been marketed outside regulated pharmaceutical channels, which raises questions about quality and claims.

The ability to control the size, flow rate, and composition of droplets provides an option to fine tune the morphology of fibers to fit a specific use in bioanalysis and emulation of anatomical functions.
Very low voltages are inefficient since the lead wires would conduct too much heat away from the filament, so the practical lower limit for incandescent lamps is 1.5 volts. Very long filaments for high voltages are fragile, and lamp bases become more difficult to insulate, so lamps for illumination are not made with rated voltages over 300 volts. Some infrared heating elements are made for higher voltages, but these use tubular bulbs with widely separated terminals.
On July 6, 2025, furious that their Acting Grand Master had been arrested, dozens of members of the High Chamber held a large protest in front of the National Masonic Temple in rejection of Filema Duarte's authority to call any session of the High Chamber. The session had been scheduled to occur later that day. However, when they tried to enter the building, the Tyler was joined by three Freemasons who sided with Filema Duarte – Jesús Martínez Frómeta, Raúl Pérez Martín and Rolando Céspedes Mena – who refused the protesters entry to the building. The two sides pushed and shoved. The protestors cried and shouted for Filema Duarte to exit the building, and he did come down to try and meet with them. But Former Grand Master Ernesto Zamora Fernández then, in a video which appeared on Zamora Fernández's Facebook profile, was seen leading a chant of "Out, traitor! Get out!" Filema Duarte retreated back into his office, with the Freemasons still shouting at him that he was a traitor to the Brotherhood and a puppet of the Cuban government. Filema Duarte issued a statement that he had cancelled the session of the High Chamber, in which he also stated that he would not be stepping aside as Grand Master. On Facebook, Zamora Fernández wrote: "This is the face of the dictatorship dressed as the Grand Master of the Cuban Masons, his name: Maikel Filema. He is worse than Agent Collera Vento. Dismissed by the Masons, he clings to power with the support of the government... Your betrayal, your lack of civility, your lack of morality, your ignorance. Your baseness, your lack of ethics.
====== Palliative medicine ====== To train in the add-on specialty of palliative medicine a physician must first be a specialist in one of the pediatric class specialties, one of the independent class specialties (excluding occupational and environmental medicine, clinical pharmacology, clinical genetics, forensic medicine, and social medicine), one of the internal medicine class specialties, one of the surgical class specialties, one of the neurological class specialties (excluding clinical neurophysiology) or one of the psychiatric class specialties.
Opioids are a class of drugs that derive from, or mimic, natural substances found in the opium poppy plant. Opioids work on opioid receptors in the brain and other organs to produce a variety of morphine-like effects, including pain relief. The terms opioid and opiate are sometimes used interchangeably, but the term opioid is often used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain, while the term opiate is often used to refer to alkaloid compounds naturally found in the opium poppy plant Papaver somniferum. Medically they are primarily used for pain relief, including anesthesia. Other medical uses include suppression of diarrhea, replacement therapy for opioid use disorder, and suppressing cough. The opioid receptor antagonist naloxone is used to reverse opioid overdose. Extremely potent opioids such as carfentanil are approved only for veterinary use. Opioids are also frequently used recreationally for their euphoric effects or to prevent withdrawal. Opioids can be fatal, and have been used, alone and in combination, in a small number of executions in the United States. Side effects of opioids may include itchiness, sedation, nausea, respiratory depression, constipation, and euphoria. Long-term use can cause tolerance, meaning that increased doses are required to achieve the same effect, and physical dependence, meaning that abruptly discontinuing the drug leads to unpleasant withdrawal symptoms. The euphoria attracts recreational use; frequent, escalating recreational use of opioids typically results in addiction.

Preservative food additives can be antimicrobial – which inhibit the growth of bacteria or fungi, including mold – or antioxidant, such as oxygen absorbers, which inhibit the oxidation of food constituents. Common antimicrobial preservatives include nisin, sorbates, calcium propionate, sodium nitrate/nitrite, sulfites (sulfur dioxide, sodium bisulfite, potassium hydrogen sulfite, etc.), EDTA, hinokitiol, and ε-polylysine. Antioxidants include tocopherols (Vitamin E), butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). Other preservatives include ethanol. There is also another approach of impregnating packaging materials (plastic films or other) with antioxidants and antimicrobials.
=== Mental health === Transgender individuals may experience distress and sadness as a result of their gender identity being inconsistent with their biological sex. This distress is referred to as gender dysphoria. Gender dysphoria is typically most upsetting for the individual prior to transitioning, and once the individual begins to transition into their desired gender, whether the transition be socially, medically, or both, the distress frequently lessens. Transgender individuals may be bullied as a result of the gender norm. Studies revolving around the effects of bullying have shown that bullying is associated with a declining mental health. Past experience predicted more depressive symptoms and a low self-worth. A study also revealed that those who came out to school peers or staff had a greater psychological well-being despite being bullied. The effects of bullying include higher risk for substance abuse, risky behaviors like drunk driving, and higher engagement in sexual risk behaviors. Being bullied also increases absenteeism and poor grades among LGTBQ individuals. Physical symptoms can also manifest as a result including abdominal pain, poor appetite, sleeping problems, increase in blood pressure, etc. These experiences as an adolescent can have negative consequence in adulthood as well. These consequence include depression, suicide attempts, lower life satisfaction, etc. Those who are transgender are significantly more likely to be diagnosed with anxiety disorders or depression than the general population.
This accounts for the majority of the other 15% of cases of CJD. Acquired CJD, caused by contamination with tissue from an infected person, usually as the result of a medical procedure (iatrogenic CJD). Medical procedures that are associated with the spread of this form of CJD include blood transfusion from the infected person, use of human-derived pituitary growth hormones, gonadotropin hormone therapy, and corneal and meningeal transplants. Variant Creutzfeldt–Jakob disease (vCJD) is a type of acquired CJD potentially acquired from bovine spongiform encephalopathy or caused by consuming food contaminated with prions. Sporadic CJD, while transmissible through tissue transplants, may not be transmitted through blood transfusion.
== History == Clocinnamox (CCAM) was first described in the scientific literature by 1992. MCCAM was first described by 1995. It was developed by researchers at the National Institute on Drug Abuse (NIDA) of the United States National Institutes of Health (NIH). The drug was of interest in the possible treatment of opioid dependence. However, it was never marketed. Methocinnamox (MCAM), a close analogue of MCCAM, was first described in 2000. MCAM was under development for the treatment of opioid dependence and opioid overdose by 2020.
Illegal efforts to weaponize methaqualone have occurred. During the 1980s, the apartheid regime in South Africa ordered the covert manufacture of a large amount of methaqualone at the front company Delta G Scientific Company, as part of a secret chemical weapons program known as Project Coast. Methaqualone was given the codename MosRefCat (Mossgas Refinery Catalyst). Details of this activity came to light during the 1998 hearings of the post-apartheid Truth and Reconciliation Commission.

No. It is not approved as a therapeutic drug by major regulators. It is sold for research purposes in many settings, which is not the same as clinical approval.
It is classified among peptide hormones and related substances that are prohibited in sport. The ban reflects anti-doping rules rather than a judgment that the peptide is effective for performance enhancement.
Human studies are limited and have not produced consistent evidence of meaningful clinical benefit. Some early trials examined metabolic endpoints, but larger confirmatory trials are generally lacking.
It is a synthetic peptide fragment derived from the C-terminal region of human growth hormone, commonly referred to as hGH fragment 176-191. It has been investigated for effects on fat metabolism, but it is not an approved medication in most jurisdictions.
