What are Peptides?

NAD+ (nicotinamide adenine dinucleotide) is a vital coenzyme found in every cell of the body. It is central to many biological processes, including: 

• Energy production: It helps convert food into cellular energy (ATP).
• DNA repair: It assists in the repair of damaged DNA and cells.
• Gene expression: It activates sirtuins, a class of enzymes th

NAD+ (nicotinamide adenine dinucleotide) is a vital coenzyme found in every cell of the body. It is central to many biological processes, including: 

• Energy production: It helps convert food into cellular energy (ATP).
• DNA repair: It assists in the repair of damaged DNA and cells.
• Gene expression: It activates sirtuins, a class of enzymes that regulate aging and other cellular functions.
• Metabolic regulation: It plays a role in regulating metabolic processes. 

Uses and purported benefits: 

NAD+ therapy is used for a variety of purposes. The intended use is to restore NAD+ levels, which naturally decline with age and may also be affected by stress, poor diet, and other factors. Potential benefits associated with increased NAD+ levels include: 

• Anti-aging and longevity: By promoting cellular repair and protecting against DNA damage, some believe NAD+ therapy can slow the aging process.
• Boosted energy and metabolism: It may help improve stamina and enhance metabolic function.
• Enhanced cognitive function: It may improve memory, focus, and mental clarity.
• Addiction recovery: Injections have shown promise in addiction treatment by potentially reducing withdrawal symptoms and cravings.
• Reduced inflammation: It may help reduce oxidative stress and inflammation, aiding in muscle recovery. 

"NAD+ peptide" delivery methods:

Since NAD+ is not a peptide, the term "NAD+ peptide therapy" is a misnomer for the method of administration. Delivery methods for NAD+ replenishment include: 

• Injections: The most common form of NAD+ therapy, where it is delivered directly into the bloodstream for higher absorption.

Efficacy and safety: 

While animal studies have shown promising results, and some human trials suggest benefits for metabolism and exercise performance, many of the clinical trials have been small. Some experts remain skeptical about the efficacy of NAD+ therapy and believe more data is needed to support the claims. The long-term safety and effectiveness of these therapies are still being studied.

 Tirzepatide is a synthetic peptide used to treat adults with type 2 diabetes, obesity, and obstructive sleep apnea. It is marketed under the brand name Mounjaro for diabetes and Zepbound for weight management and sleep apnea. As the first "twincretin," tirzepatide works by mimicking two natural gut hormones:

• Glucose-dependent insulinotropic polypeptide (GIP)
• Glucagon-like peptide-1 (GLP-1) 

By activating both GIP and GLP-1 receptors, the drug achieves its therapeutic effects.

 Uses for tirzepatideType 2 diabetes:

Tirzepatide is used along with diet and exercise to help adults control their blood sugar. It manages blood sugar by: 

• Increasing insulin production by the pancreas when blood glucose levels are high.
• Decreasing glucagon from the liver, which reduces the amount of sugar the liver releases.
• Slowing down gastric emptying, which helps regulate post-meal blood sugar spikes. 

Chronic weight management: 

The medication is prescribed for weight loss in adults who are obese or overweight with weight-related medical conditions. It aids weight loss by: 

• Reducing appetite and food cravings, partly by affecting appetite-regulating areas in the brain.
• Increasing the feeling of fullness, which helps decrease food intake.
• Counteracting hunger hormones like ghrelin. 

Obstructive sleep apnea (OSA):

Tirzepatide treats moderate-to-severe OSA in adults with obesity. It addresses the condition primarily through weight loss, which is a major contributor to OSA. The medication may also reduce inflammation associated with the condition. 

How tirzepatide is administered:

Tirzepatide is an injectable medicine, typically given as a once-weekly subcutaneous (under the skin) injection. The dosage is usually started low and increased gradually under the supervision of a doctor to minimize potential gastrointestinal side effects.  

Retatrutide is an experimental peptide that targets multiple hormone receptors to treat obesity and type 2 diabetes.

Semaglutide is a peptide-based medication used to treat type 2 diabetes, promote long-term weight management, and reduce major cardiovascular risks in certain adults. It is a synthetic version of the naturally occurring hormone glucagon-like peptide-1 (GLP-1), and its uses differ depending on the brand name.

 What it is used for:

FDA-approved indications for semaglutide vary by product name:

• Ozempic (injection): Treats type 2 diabetes and reduces the risk of heart attack, stroke, and cardiovascular death in adults with type 2 diabetes and heart disease.
• Rybelsus (oral tablet): Improves blood sugar control in adults with type 2 diabetes.
• Wegovy (injection): Facilitates chronic weight management in adults and adolescents (ages 12 and older) who are overweight or obese with at least one related medical condition. It is also approved for reducing cardiovascular event risks in adults with heart disease and for treating metabolic dysfunction-associated steatohepatitis (MASH) with liver fibrosis. 

How it works:

Semaglutide mimics the GLP-1 hormone, which is released in the gut after eating. This action helps to regulate blood sugar and appetite in several ways: 

• Stimulates insulin release: Signals the pancreas to produce more insulin when blood sugar is high.
• Slows stomach emptying: Extends the feeling of fullness and decreases overall food intake.
• Regulates appetite: Affects the appetite centers in the brain, which leads to reduced hunger and cravings.
• Decreases glucagon: Reduces the production of glucagon, a hormone that increases blood sugar.

Common side effects:

The most common side effects of semaglutide are typically mild and often occur when starting the medication or increasing the dose. These include gastrointestinal issues such as: 

• Nausea
• Vomiting
• Diarrhea
• Constipation
• Stomach pain 

Important considerations:

• Not a quick fix: For weight management, semaglutide is a long-term treatment that requires consistent lifestyle changes, including diet and exercise, for sustained results.
• "Off-label" use: While some healthcare providers may prescribe semaglutide brands like Ozempic for weight loss, it is important to note that this is an "off-label" use.
• Not for everyone: Individuals with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 should not take semaglutide.

 TB-500 is a synthetic injectable peptide that mimics the naturally occurring protein thymosin beta-4 (Tβ4), which plays a key role in tissue repair and regeneration. It is not approved by the Food and Drug Administration (FDA) for human use and is typically sold for research purposes only. 

How TB-500 works

TB-500 works by influencing several cellular processes to promote healing and reduce inflammation throughout the body: 

• Promotes cell migration: It regulates the protein actin, which enhances the movement of cells to the sites of injury.
• Enhances blood vessel growth: By stimulating angiogenesis, TB-500 increases blood flow to damaged tissues, improving the delivery of oxygen and nutrients essential for repair.
• Reduces inflammation: It helps to decrease the production of pro-inflammatory substances, creating a better environment for healing.
• Encourages tissue remodeling: It supports the production and organization of collagen, the main protein in tendons, ligaments, and skin, which can help improve tissue strength and reduce scar tissue. 

Potential uses and benefitsDue to its regenerative properties, TB-500 is promoted for several applications, particularly in sports medicine and regenerative health: 

• Accelerated recovery from muscle, tendon, and ligament injuries.
• Increased flexibility and reduced inflammation associated with chronic conditions like tendinitis or arthritis.
• Support for post-surgical recovery.
• Healing of cuts, wounds, and other tissue damage.

 AOD-9604 is a synthetic peptide derived from human growth hormone (hGH) that has been investigated for its potential to aid in fat loss. It is sometimes called the "fat-burning peptide".

 How it works

• AOD-9604 is a modified version of the hGH fragment consisting of amino acids 177–191.
• It is designed to specifically target fat metabolism, triggering the breakdown of fat stores (lipolysis) without affecting blood sugar or insulin levels.
• Unlike the full human growth hormone, AOD-9604 does not appear to cause muscle growth (anabolic effects), though some reports are conflicting. 

Development and regulatory status

• Initial research: AOD-9604 was originally developed by Monash University in Australia as a potential anti-obesity drug in the 1990s.

• Clinical trials: Early studies explored its effects on fat metabolism in animals. Some human trials were conducted, but they did not show "a clinically meaningful weight loss outcome across the trial population," and the obesity program was abandoned in 2007.
• Safety data: Multiple non-clinical studies in rats and monkeys showed no evidence of genotoxic or toxicological concerns.

• Regulatory status:
  • The peptide has not been approved for therapeutic use by the U.S. Food and Drug Administration (FDA) or other major health authorities for weight loss.
  • The World Anti-Doping Agency (WADA) has banned its use in sports.
  • The FDA has identified compounded drugs containing AOD-9604 as potentially having significant safety risks and has raised concerns about the lack of robust safety data.

• Current use: Despite its unapproved status for weight loss, AOD-9604 is offered by some clinics and wellness centers for weight management. It can be administered via injection or as a troche (a medicated lozenge). 

Associated risks and concerns

• Uncertain effectiveness: The limited human data and the failure of past clinical trials mean there is no robust evidence that AOD-9604 is effective for weight loss in the general population.

• Regulatory warning: The FDA's identification of potential safety risks for compounded versions of the drug highlights the importance of caution.

• Off-label use: When used for weight loss, the peptide is being used "off-label," without official regulatory approval for that purpose.
