With the recent popularity of peptides for muscle growth, many people are wondering if they are legal. The answer to this question depends on the country in which you reside. In the United States, peptides are not currently regulated by the Food and Drug Administration (FDA). This means that they can be bought and sold without a prescription. However, it is important to note that the FDA has not approved peptides for human use. Therefore, they should be used for research purposes only. In other countries, such as Australia, peptides are regulated as therapeutic goods and can only be obtained with a prescription.
The use of peptides and proteins as growth promoters is a major issue for sport and food regulatory agencies. The efficacy of these compounds in growth-promoting effects make them susceptible to abuse by athletes or farmers who seek to illicitly enhance muscle growth. MS is well-established for qualitative analysis of peptides and proteins, and is becoming more widely accepted for quantitative analysis. Improvements of current detection strategies with state-of-the-art MS instrumentation are discussed for qualitative and quantitative approaches to peptide and protein analysis.
The digestion of muscle protein can release bioactive peptides that have various health benefits. The cooking condition of muscle food can critically affect the digestibility of the protein and the release of peptides. The enzymatic hydrolysis of protein can also release bioactive peptides, but the optimal condition for peptide production must be considered. The bioactivities of peptides may be changed during gastrointestinal digestion and transport. In order to develop functional food or nutraceutical products, the efficacy of bioactive peptides should be tested in vivo.
Bioactive peptides from food proteins can be used in functional foods and nutraceuticals. A variety of bioactive peptides have been identified in plant, milk, and muscle growth proteins, including those from beef, chicken, pork, and fish. Most research on bioactives from meat sources has focused on angiotensin-1-converting enzyme (ACE) inhibitory and antioxidant peptides.
Peptide therapeutics are potential safe and effective therapeutic agents that have less side effects than small molecule drugs. However, their production is expensive and presents side effects. Studies have shown that peptides with bioactive properties can be released from food proteins. These bioactivities include antithrombotic, antihypertensive, immunomodulatory and antioxidant properties. Bioactive peptides could serve as potential therapeutic agents. The lack of commercially-viable processes for large-scale production of peptide therapeutics has been a major hindrance to their application as therapeutic aids.
The use of hormones to improve physical fitness is a common practice, but it can have harmful effects. Insulin, hormone growth, thyroid hormones, and erythropoitin can all cause damage to the body if they are abused. This can lead to paralysis, muscle damage and loss, diabetes, and other health problems.
