Best Supplements For Muscle Growth designed to mimic the muscle-building and performance-enhancing effects of anabolic steroids without containing any controlled substances. They typically comprise a blend of natural ingredients like plant extracts, vitamins, minerals, and amino acids. These ingredients are believed to work synergistically to boost muscle growth, strength, and endurance. It's crucial to understand that while they are termed "legal steroids," they are not actual steroids. They are dietary supplements regulated differently than prescription medications. The term "legal steroid" is primarily a marketing term.
