Everything below concerns Reconstitution. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-10-18. Where a claim depends on a specific study, the study is described rather than over-claimed.
Naming in this area is inconsistent, and readers should treat product labels with care. In much of the literature and in vendor catalogs, the unqualified term refers to the albumin-binding version, while the version lacking the DAC group appears as modified GRF(1-29), mod GRF(1-29), or the same name with a without-DAC qualifier. Because one abbreviation has been applied to both materials, the only reliable way to identify a sample is to check the stated sequence and the presence of the linker.
CJC-1295 is the name used for a synthetic peptide modeled on growth hormone-releasing hormone, the hypothalamic signal that prompts the pituitary to release growth hormone. The compound was described by a Canadian drug discovery company in the mid-2000s as a long-acting research tool. Two closely related molecules share the name in practice: one carries a drug affinity complex, or DAC, group, and one does not. The distinction matters because the two behave differently in circulation.
Both forms act at the pituitary receptor for growth hormone-releasing hormone and increase growth hormone output, which in turn raises insulin-like growth factor 1. A long-acting analog produces sustained rather than pulsatile stimulation, and the physiological consequences of that pattern are not fully settled. Published human data on the extended form remain limited, and much of what circulates in discussion traces to early company reports rather than independent replication. How sustained exposure affects normal feedback remains an open question.
The distinguishing feature of the DAC form is a maleimide-containing group that reacts with the free thiol of cysteine-34 on human serum albumin. This reaction forms a covalent bond without enzymatic assistance, and it takes place after the peptide enters the bloodstream. Because albumin is abundant and long-lived, the attached peptide is carried through circulation far longer than an unmodified fragment would survive. The chemistry is a deliberate pharmacokinetic strategy rather than a change to receptor activity.
Enzymatic protection is a separate mechanism from plasma protein binding. The four substitutions in the backbone reduce recognition by dipeptidyl peptidase IV, which normally cleaves the natural hormone within minutes. Without the reactive group, this resistance still yields only a short window of activity, generally reported in the range of tens of minutes. With it, reported half-lives in early human work extended to several days. The size of that gap is the main practical distinction between the two materials.
| Property | Value | Notes |
|---|---|---|
| Molecular class | Synthetic peptide | GHRH analog, not a steroid |
| Backbone length | 29 amino acids | Based on GRF(1-29) |
| Substitutions | Four positions | D-Ala2, Gln8, Ala15, Leu27 |
| Appearance | White to off-white powder | Typical lyophilized research material |
| Common synonyms | Modified GRF(1-29) | Usage varies between sources |
Pharmacokinetic behaviour differs sharply between the two forms. The DAC-bearing peptide shows an extended circulation time measured in days, whereas the version without the complex is cleared within roughly half an hour. This gap shapes how researchers design dosing schedules in animal models. Whether the prolonged presence of the DAC form produces effects meaningfully different from the short-acting variant remains an open question, since comparative human data are scarce.
CJC-1295 is a synthetic peptide designed to mimic growth hormone-releasing hormone (GHRH), the endogenous signal that prompts the pituitary gland to release growth hormone. The compound is a modified fragment of the natural hormone, spanning the first twenty-nine amino acids of GHRH with several substitutions that slow enzymatic breakdown. Two variants circulate in research settings: one carrying a drug affinity complex (DAC) and one without it. The DAC-free form is frequently labelled Mod GRF(1-29) in catalogs and discussion forums.
The peptide binds GHRH receptors on somatotroph cells within the anterior pituitary, triggering a signalling cascade that increases growth hormone secretion. Its improved resistance to dipeptidyl peptidase IV degradation distinguishes it from the parent hormone. In the DAC-bearing version, a maleimide group reacts with a cysteine residue on serum albumin, forming a covalent bond that keeps the peptide in circulation far longer. That albumin attachment is the central design feature separating the two research variants.
The drug affinity complex is a maleimidopropionic acid group attached to a lysine side chain. It reacts with the free thiol of cysteine-34 on circulating albumin, forming a covalent bond. This conjugation keeps the peptide in the bloodstream and shields it from rapid renal filtration and proteolysis. Reported circulation half-lives for the albumin-bound form fall in the range of roughly six to nine days in early human studies.
Binding to GHRH receptors on pituitary somatotroph cells triggers cyclic AMP signaling and stimulates growth hormone synthesis and release. Because the peptide acts upstream of the pituitary, effects are mediated through endogenous growth hormone rather than direct receptor activation in peripheral tissues. Increases in insulin-like growth factor 1 are generally described as a downstream consequence. Most published human exposure data come from small early-stage studies, and the clinical significance of the pharmacokinetic profile remains incompletely characterized.
CJC-1295 is a synthetic analogue of growth hormone-releasing hormone, built on the 29-amino-acid GHRH(1-29) fragment. Four substitutions distinguish it from the natural sequence: D-alanine at position 2, glutamine at position 8, alanine at position 15, and leucine at position 27. These changes reduce enzymatic cleavage and extend the peptide's persistence in circulation. The compound is discussed in two forms, one carrying a drug affinity complex and one without it.
Peptide degradation proceeds mainly through hydrolysis, oxidation of methionine, and deamidation of asparagine or glutamine residues. The maleimide group on the albumin-binding variant can also react with thiols or hydrolyze in aqueous media. Because these pathways accelerate with temperature and pH extremes, handling conditions strongly influence measured stability. Stability data in the public literature are limited and often generated under differing conditions, so general statements about shelf life should be read as approximate.
Research material is normally supplied as a freeze-dried powder in sealed vials. In that state the peptide is comparatively robust, but prolonged exposure to warmth, moisture, or light accelerates degradation. Storage at minus twenty degrees Celsius or lower, with desiccant and protection from light, is the commonly described practice. Vials should be allowed to reach room temperature before opening to limit condensation on the powder. Moisture uptake during handling is a recognized source of variability in later measurements.
== Personal life == On 6 March 2024, al-Burhan's son, Mohammed Fattah Burhan Rahman, was severely injured after his motorcycle collided with another vehicle in Ankara, Turkey. He died of his injuries on 3 May after spending nearly two months in intensive care.
=== Product invention === As recently as July 21, 2011, LifeVantage credited McCord as the creator of Protandim on its website. At a 2011 conference for LifeVantage distributors, McCord stated, "I was presented with a list of 41 potential ingredients for a product they wanted to call Protandim, and I went through the list and penciled out, rapidly, about 36 of those ingredients," leaving the 5 ingredients in the current formulation of Protandim. In March 2009, former LifeLine Therapeutics executive, Paul Myhill stated, "We initially decided to hide that fact [that Myhill derived the core composition for Protandim] for marketing purposes and instead rely on the impeccable background of Dr. McCord." In April, 2005, Myhill produced a signed letter from McCord in which McCord stated, "I do not honestly feel that I have made contributions to the intellectual property, up to this point, that would qualify me as an inventor...I must congratulate you and Paul for having framed the concept of Protandim so close to its final embodiment, prior to the beginnings of our association."
The bioavailability of spironolactone when taken by mouth is 60 to 90%. The bioavailability of spironolactone and its metabolites increases significantly (+22–95% increases in levels) when spironolactone is taken with food, although it is uncertain whether this further increases the therapeutic effects of the medication. The increase in bioavailability is thought to be due to promotion of the gastric dissolution and absorption of spironolactone, as well as due to a decrease of the first-pass metabolism. The relationship between a single dose of spironolactone and plasma levels of canrenone, a major active metabolite of spironolactone, has been found to be linear across a dose range of 25 to 200 mg spironolactone. Steady-state concentrations of spironolactone are achieved within 8 to 10 days of treatment initiation. Little or no systemic absorption has been observed with topical spironolactone.
Kyiv came under air attack in the early hours of the morning. Vitali Klitschko, Kyiv's Mayor, said that debris from intercepted missiles struck the city zoo in the Solomianskyi District and the Shevchenkivskyi District, as well as several cars, and wounded three people. According to Kyiv's military administrator, Serhiy Popko, the attack was "exceptional", as it involved "the maximum number of attack missiles in the shortest period of time." Ukraine stated all eighteen missiles were shot down, including six Kh-47M2 Kinzhal missiles. The attacks came from the north, south and east while being launched from air, land and sea, according to Ukrainian military commander Valerii Zaluzhny. However, Russian Defence Minister Sergei Shoigu dismissed the Ukrainian claims, saying that they had launched a lesser amount of missiles. The Russian Ministry of Defence claimed to have destroyed a US-built Patriot surface-to-air missile defense system with a Kinzhal missile. A US official later told CNN that a Patriot system was likely damaged but not destroyed during the attack, and that assessments for potential damage were ongoing. According to a US official the Patriot system could be repaired in Ukraine. Due to modular nature of the system it may just require the replacement of a damaged component with a new one. Denis Pushilin, head of the Russian-backed Donetsk People's Republic, said that Russian forces had seized several Ukrainian positions near Avdiivka.
== Origin and foundations == Dora Kunz, a theosophy promoter and one-time president (1975–1987) of the Theosophical Society in America, and Dolores Krieger, now Professor Emerita of Nursing Science, New York University, developed therapeutic touch in the 1970s. According to Krieger, therapeutic touch has roots in ancient healing practices, such as the laying on of hands, although it has no connection with religion or with faith healing. Krieger states that, "in the final analysis, it is the healee (client) who heals himself. The healer or therapist, in this view, acts as a human energy support system until the healee's own immunological system is robust enough to take over." Justification for TT has been sought in two fields: Martha E. Rogers' contemporal "Science of Unitary Human Beings", and quantum mechanics, in particular Fritjof Capra's mystical interpretation of the latter. A 2002 review found that neither justification was tenable: Rogers's theories were found to be inconsistent with the tenets of TT, while the overlap in terminology between the two could be ascribed to a lack of precision in Rogers's works, making them multi-interpretable. The quantum physics justification holds that the possibility to heal at a distance is made possible by a "global interconnectivity" of the universe, which TT adherents ascribe to an interpretation of Bell's theorem and the possibility of quantum nonlocality; this interpretation is not supported by experimental evidence.

=== Recommended dietary intake === The WHO recommends that both adults and children reduce the intake of free sugars to less than 10% of total energy intake. "Free sugars" include monosaccharides and disaccharides added to foods, and sugars found in fruit juice and concentrates, as well as in honey and syrups. On 20 May 2016, the United States Food and Drug Administration announced changes to the Nutrition Facts panel displayed on all foods, to be effective by July 2018. New to the panel is a requirement to list "added sugars" by weight and as a percentage of Daily Value (DV). For vitamins and minerals, the intent of DVs is to indicate how much should be consumed. For added sugars, the guidance is that 100% DV should not be exceeded. 100% DV is defined as 50 grams. For a person consuming 2000 calories a day, 50 grams is equal to 200 calories and thus 10% of total calories – the same guidance as the WHO. To put this in context, most 12-US-fluid-ounce (355 ml) cans of soda contain 39 grams of sugar. In the United States, a government survey on food consumption in 2013–14 reported that, for men and women aged 20 and older, the average total sugar intakes – naturally occurring in foods and added – were, respectively, 125 and 99 grams per day. The American Heart Association recommends even lower daily consumption of added sugars: 36 grams for men and 25 grams for women.
=== Volatile organic compounds === Individual honeys from different plant sources contain over 100 volatile organic compounds (VOCs), which play a primary role in determining honey flavors and aromas. VOCs are carbon-based compounds that readily vaporize into the air, providing aroma, including the scents of flowers, essential oils, or ripening fruit. The typical chemical families of VOCs found in honey include hydrocarbons, aldehydes, alcohols, ketones, esters, acids, benzenes, furans, pyrans, norisoprenoids, and terpenes, among many others and their derivatives. The specific VOCs and their amounts vary considerably between different types of honey obtained by bees foraging on different plant sources. By example, when comparing the mixture of VOCs in different honeys in one review, longan honey had a higher amount of volatiles (48 VOCs), while sunflower honey had the lowest number of volatiles (8 VOCs). VOCs are primarily introduced into the honey from the nectar, where they are excreted by the flowers imparting individual scents. The specific types and concentrations of certain VOCs can be used to determine the type of flora used to produce monofloral honeys. The specific geography, soil composition and acidity used to grow the flora also have an effect on honey aroma properties, such as a "fruity" or "grassy" aroma from longan honey, or a "waxy" aroma from sunflower honey. Dominant VOCs in one study were linalool oxide, trans-linalool oxide, 2-phenylacetaldehyde, benzyl ethanol, isophorone, and methyl nonanoate.
== Types of nuclear warfare == Nuclear warfare scenarios are usually divided into two groups, each with different effects and potentially fought with different types of nuclear armaments. The first, a limited nuclear war (sometimes attack or exchange), refers to the controlled use of nuclear weapons, whereby the implicit threat exists that a nation can still escalate their use of nuclear weapons. For example, using a small number of nuclear weapons against strictly military targets could be escalated through increasing the number of weapons used, or escalated through the selection of different targets. Limited attacks are thought to be a more credible response against attacks that do not justify all-out retaliation, such as an enemy's limited use of nuclear weapons. The second, a full-scale nuclear war, could consist of large numbers of nuclear weapons used in an attack aimed at an entire country, including military, economic, and civilian targets. Such an attack would almost certainly destroy the entire economic, social, and military infrastructure of the target nation, and would likely have a devastating effect on Earth's biosphere. Some Cold War strategists such as Henry Kissinger argued that a limited nuclear war could be possible between two heavily armed superpowers (such as the United States and the Soviet Union). Some predict, however, that a limited war could potentially "escalate" into a full-scale nuclear war.
=== Academia === Prior to his postdoctoral fellowship, Kopeček served as the research scientific officer for the Institute of Macromolecular Chemistry at the Czechoslovak Academy of Sciences from 1965 to 1967. He then served in the same capacity after his postdoctoral fellowship at the National Research Council of Canada until 1972, when he became the head of the Laboratory of Medical Polymers at the Institute of Macromolecular Chemistry from 1972 to 1980. Kopeček then became head of the Laboratory of Biodegradable Polymers until 1988. In 1986, Kopeček became co-director for the Center of Controlled Chemical Delivery of Utah and was a visiting professor. From 1989, he was professor of bioengineering and professor of pharmaceutics and pharmaceutical chemistry. As of 2002, Kopeček has been a distinguished professor in both pharmaceutical chemistry and biomedical engineering. In 2017, he became the director for the Center of Controlled Chemical Delivery at the University of Utah.
Treating Type 2 Diabetes with glucose mimetics Mason found the common denominator between gastric and intestinal bypass when treating type 2 diabetes in 1998. The exposure of the distal bowel to glucose or other stimulants such as glucose mimetics resulted in the secretion of GLP-1 (glucagon-like peptide-1) hormones, which could potentially treat diabetes type-2 disease. Gastric bypass surgery treated type-2 diabetes through weight loss and the release of GLP-1 hormones. To treat diabetes-type 2 patients without surgery, he thought that using a form of glucose substitute or glucose mimetic that would reach the distal ileum before it was absorbed could be a simple and cost-effective treatment. He suggested using glucose mimetic d-tagatose in addition to weight reduction with a proper diet and increased physical activity.

No. It is a laboratory-made analog of growth hormone-releasing hormone. The natural hormone is a 44-residue peptide, while the analog is built on a shorter 29-residue fragment.
The original material included a linker that binds serum albumin. A later variant removed that linker to reduce the duration of action. Catalogs and papers did not consistently adopt separate names, so both remain widely labeled with the same term.
The amino acid sequence and the presence or absence of the linker group. Mass measured by spectrometry gives an independent check that separates the two forms.
A maleimide moiety reacts with the thiol of cysteine-34, forming a covalent bond. The reaction occurs in circulation without enzymatic catalysis.
