AOD-9604 is a synthetic peptide that corresponds to a short section of human growth hormone. It is commonly identified as hGH fragment 176-191 because its sequence matches residues at the C-terminal end of the hormone. The molecule contains sixteen amino acids and is made by solid-phase peptide synthesis. Researchers study it for metabolic effects rather than for the growth-promoting actions associated with full human growth hormone. Its small size distinguishes it from the complete 191-amino-acid hormone.
Several names appear in scientific and commercial settings. AOD9604 and AOD-9604 are development codes used interchangeably, while hGH fragment 176-191 describes the same region. The peptide includes a disulfide bond between two cysteine residues, which helps shape its three-dimensional structure. Different suppliers may provide acetate or other salt forms, and purity can vary. These differences matter because analytical tests and biological assays can respond to the specific form being studied.
AOD-9604 drew attention in the 1990s and 2000s as a potential anti-obesity agent. Early work explored both injectable and oral routes, which is unusual for a peptide of this size. Animal studies reported changes in fat metabolism without the growth-promoting or insulin-like effects associated with full-length growth hormone. Subsequent human trials produced mixed or modest results, and the compound did not obtain regulatory approval for weight management in major markets. It remains known mainly through research literature, sports anti-doping listings, and non-approved supplement advertising.
AOD-9604 is prohibited in sport by the World Anti-Doping Agency under the peptide hormone class. Its presence in a sample can be detected through mass spectrometry-based methods, although the exact assay depends on the laboratory. In research settings, material is often supplied as a lyophilized powder for reconstitution. Buyers and researchers should note that products labeled AOD-9604 may vary in purity and actual peptide content. Analytical certificates and independent testing are common ways to verify identity, but no global harmonized standard exists for all commercial lots.

AOD-9604 is a synthetic peptide modeled on the C-terminal region of human growth hormone. It corresponds to residues 176-191 of the 191-amino-acid hGH sequence. The fragment is not the full hormone and lacks the receptor-binding region associated with growth and metabolic effects of hGH. Researchers developed it to isolate a specific portion of hGH for study. Its exact sequence and length are often stated in peptide catalogs and patents.
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.
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.
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 parathyroid glands, of which there are 4–6, are found on the back of the thyroid glands, and secrete parathyroid hormone. This causes an increase in blood calcium levels by targeting bone, the intestine, and the kidneys. The parathyroid hormone is the antagonist of calcitonin. Parathyroid hormone release is triggered by falling blood calcium levels and is inhibited by rising blood calcium levels.
Generally all gingival diseases share common features such as signs and symptoms being restricted to gingiva, clinically detectable inflammation, and the potential for the gum tissues to return to a state of health once the cause is removed, without irreversible loss of attachment of the teeth.
14N, though also theoretically usable, has an integer nuclear spin of one and thus has a quadrupole moment that leads to wider and less useful spectra. 15N NMR nevertheless has complications not encountered in the more common 1H and 13C NMR spectroscopy. The low natural abundance of 15N (0.36%) significantly reduces sensitivity, a problem which is only exacerbated by its low gyromagnetic ratio, (only 10.14% that of 1H). As a result, the signal-to-noise ratio for 1H is about 300 times as much as that for 15N at the same magnetic field strength. This may be somewhat alleviated by isotopic enrichment of 15N by chemical exchange or fractional distillation. 15N-enriched compounds have the advantage that under standard conditions, they do not undergo chemical exchange of their nitrogen atoms with atmospheric nitrogen, unlike compounds with labelled hydrogen, carbon, and oxygen isotopes that must be kept away from the atmosphere. The 15N:14N ratio is commonly used in stable isotope analysis in the fields of geochemistry, hydrology, paleoclimatology and paleoceanography, where it is called δ15N. Of the thirteen other isotopes produced synthetically, ranging from 9N to 23N, 13N has a half-life of ten minutes and the remaining isotopes have half-lives less than eight seconds.
Gifts were presented to the Grand Lodge of Cuba from the various delegations. Brother Winslow, from the United States, presented a ceremonial folded American flag as a gift, and read from a handwritten letter by Freemason and former President of the United States, Harry S. Truman. In the letter, the Truman apologized that he could not attend the event due to poor health, but said that he was with them in spirt, wishing them good fortune and prosperity. The Grand Lodge of Chile presented a group of sculptures, including a prominent sculpture of Bernardo O'Higgins riding victorious on a sorrel horse. The Grand Lodge of Florida presented a plaque that would be installed in the lobby of the National Masonic Temple. The delegation from the Grand Lodge of Pennsylvania brought out the original Charter of the Temple of the Theologic Virtues No. 103, written in 1804, of which they had kept safeguarded in their custody at the archives of the Masonic Temple in Philadelphia since 1821. Jorge Luis Cuervo Calve gave the closing speech. In it, he explained that Cuban Freemasons had led the charge to free Cuba from viscous dictators. Freemasonry itself guided them to independence and liberty. He told the history of Cuban Freemasonry "without omitting any detail." Then, he specifically thanked the delegation from Chile for being there that night, and emphasized their fraternal bonds. He then ended by stating that the spirit of the Mambises was still alive and well in the Grand Lodge of Cuba.

=== Psychoactive ingredients === According to the United Nations Office on Drugs and Crime (UNODC), "the amount of THC present in a cannabis sample is generally used as a measure of cannabis potency." The three main forms of cannabis products are the flower/fruit, resin (hashish), and oil (hash oil). The UNODC states that cannabis often contains 5% THC content, resin "can contain up to 20% THC content", and that "Cannabis oil may contain more than 60% THC content." Studies have found that the potency of illicit cannabis has greatly increased since the 1970s, with THC levels rising and CBD levels dropping. It is unclear, however, whether the increase in THC content has caused people to consume more THC or if users adjust based on the potency of the cannabis. It is likely that the higher THC content allows people to ingest less tar. At the same time, CBD levels in seized samples have lowered, in part because of the desire to produce higher THC levels and because more illegal growers cultivate indoors using artificial lights. This helps avoid detection but reduces the CBD production of the plant. Australia's National Cannabis Prevention and Information Centre (NCPIC) states that the buds (infructescences) of the female Cannabis plant contain the highest concentration of THC, followed by the leaves. The stalks and seeds have "much lower THC levels". The UN states that the leaves can contain ten times less THC than the buds, and the stalks 100 times less THC. After revisions to cannabis scheduling in the UK, the government moved cannabis back from a class C to a class B drug.
=== Chest === Important anatomy in the chest includes the chest wall, ribs, spine, spinal cord, intercostal neurovascular bundles, lungs, bronchi, heart, aorta, major vessels, esophagus, thoracic duct, and diaphragm. Gunshots to the chest can thus cause severe bleeding (hemothorax), respiratory compromise (pneumothorax, hemothorax, pulmonary contusion, tracheobronchial injury), cardiac injury (pericardial tamponade), esophageal injury, and nervous system injury. Initial workup as outlined in the Workup section is particularly important with gunshot wounds to the chest because of the high risk for direct injury to the lungs, heart, and major vessels. Important notes for the initial workup specific for chest injuries are as follows. In people with pericardial tamponade or tension pneumothorax, the chest should be evacuated or decompressed if possible prior to attempting tracheal intubation because the positive pressure ventilation can cause hypotention or cardiovascular collapse. Those with signs of a tension pneumothorax (asymmetric breathing, unstable blood flow, respiratory distress) should immediately receive a chest tube (> French 36) or needle decompression if chest tube placement is delayed. FAST exam should include extended views into the chest to evaluate for hemopericardium, pneumothorax, hemothorax, and peritoneal fluid. Those with cardiac tamponade, uncontrolled bleeding, or a persistent air leak from a chest tube all require surgery. Cardiac tamponade can be identified on FAST exam.
== History == In 1975, Tony Tan Caktiong and his family opened a Magnolia ice cream parlor in Cubao, Quezon City. The outlet later began offering hot meals and sandwiches. When the food items became more popular than ice cream, the family decided to convert the ice cream parlor into a fast food restaurant, which became the first Jollibee outlet in 1978. Management consultant Manuel C. Lumba advised the family on the change in strategy. Jollibee was initially named "Jolibe", but changed its name to "Jollibee". Jollibee Foods Corporation (JFC) was incorporated in January 1978. By the end of that year, there were seven Jollibee branches in Metro Manila. The first franchised outlet of Jollibee opened in Santa Cruz, Manila, in 1979. Jollibee experienced rapid growth. The chain was able to withstand the entry of McDonald's into the Philippines in 1981 by focusing on the specific tastes of the Filipino market. The first provincial Jollibee outlet opened in Mabalacat, Pampanga. The first overseas Jollibee opened in Singapore in 1985 at the Katong Shopping Centre; that location closed only a year later (since returned in 2013). In the same year, Jollibee opened branches in the Middle East and Guam. Jollibee continued to expand and set up outlets both within the country and abroad. Jollibee first overseas outlet opened in Brunei Darussalam on 28 August 1987 at the Utama Bowling Centre which is still operating; 35 Jollibee personnel were sent to Bandar Seri Begawan for its first outlet.
