What are peptides?
Peptides are short chains of amino acids that act as messengers in the body. They help regulate metabolism, support tissue repair, influence immune function, and are widely studied for their roles in anti-aging, wellness, and performance.
How do peptides differ from proteins?
Proteins are long, complex chains of amino acids, while peptides are shorter (usually 2-50 amino acids). Peptides often work as signals, while proteins tend to serve structural or enzymatic roles.

  • Immune & Inflammatory: (Thymosin Alpha-1, BPC-157/TB-500)
Are your peptides synthetic or natural?
All of our products are synthesized in state-of-the-art laboratories for maximum purity, stability, and consistency.
What is the difference between peptides and SARMs?
While both are research compounds, they have different mechanisms of action. Peptides are short chains of amino acids that signal the body to perform specific functions, like a hormone. SARMs (Selective Androgen Receptor Modulators) are non-steroidal compounds that target specific androgen receptors in muscle and bone tissue. Peptides are typically more focused on signaling pathways, while SARMs are primarily related to anabolic effects.
What purity can I expect?
Each batch is tested to ensure ≥99% purity.
