FDA Peptide Review Results: 6 Out of 7 Peptide Pass

On 23 and 24 July 2025, the FDA’s Pharmacy Compounding Advisory Committee (PCAC) convened to review seven peptide-related compounds being considered for potential inclusion on the 503A Bulks List. After two days of discussion, six of the seven received positive recommendations from the committee. One did not. For a field that has operated in a

The Different Peptide Formats, Explained

When people first encounter Peptide Therapy research, the format a compound comes in can seem like a practical detail rather than a scientific one. The route of administration changes where in the body a peptide can reach, how much of it enters circulation, and which biological systems it is positioned to interact with. The two

Peptides Studied in Women’s Health Research

Women’s physiology involves a set of hormonal and biological processes that shift considerably across different life stages. From the mid-thirties onward, these shifts begin to influence several interconnected systems simultaneously, including skin biology, connective tissue integrity, sleep regulation, stress resilience, and cognitive function. Research into women’s health peptides has grown alongside a broader interest in

What the Nootropic Industry Gets Wrong About Brain Health

When people describe what they want from a nootropic, the answer tends to be some combination of greater focus, sharper memory, and the ability to keep performing when concentration starts to fade. These are reasonable goals, and the most common way of pursuing them involves stimulating the brain’s existing chemistry to produce more output in

Stopping Peptide Therapy: What You Need To Know

There is no shortage of information about starting a peptide cycle. Protocols, dosing schedules, and expected benefits are well documented. What receives far less attention is the other end of the process. Stopping Peptide Therapy is a biological event in its own right, and for a meaningful proportion of people, the transition off a cycle
