Industry, Market and Research Developments
The peptide market moved fast between 2024 and 2026: GLP-1 demand reshaped supply, several vendors shut down, and manufacturers invested in new synthesis and purification capacity. This chapter collects those developments.
Oct 2, 2026Telehealth Peptide Therapy: How Remote Access Works
Most peptide therapy in the US is now delivered by telehealth. This chapter covers how remote prescribing works, state licensing limits, and how telehealth compares with in-person care.
Oct 2, 2026Immune and Inflammatory Peptides: Monographs
Immune-modulating peptides have the longest clinical history of the research-stage groups, but most human data comes from outside the US.
Oct 2, 2026Sexual Health and Hormone Peptides: Monographs
PT-141 (bremelanotide) is the only FDA-approved entry here; the remainder are research-stage or prescribed off-label.
Oct 2, 2026Skin, Hair and Aesthetic Peptides: Monographs
Cosmetic peptides are the one group where topical delivery is the norm rather than the exception, which changes both the safety profile and the regulatory picture.
Oct 2, 2026Cognitive, Mood and Sleep Peptides: Monographs
Nootropic and neuropeptide compounds are mostly studied outside the US, and much of the human literature is small or uncontrolled.
Oct 2, 2026Longevity and Anti-Aging Peptides: Monographs
Longevity peptides are the most speculative group in this guide: mechanistic rationale is strong, human outcome data is thin.
Oct 2, 2026Tissue Repair and Healing Peptides: Monographs
BPC-157, TB-500 and the blended products built from them dominate this category. The evidence base is overwhelmingly preclinical, and regulatory status is the practical constraint.
Oct 2, 2026Growth Hormone and Performance Peptides: Monographs
This group splits cleanly in two: FDA-approved secretagogues such as sermorelin and tesamorelin, and a much larger set of research-stage compounds sold for physique and recovery goals.
Oct 2, 2026Weight Loss and Metabolic Peptides: Monographs
The metabolic class is the only group in this guide with large, completed human trials behind it — GLP-1 receptor agonists are approved medicines with defined titration schedules. The other compounds here are investigational.
Oct 2, 2026Clinical Protocols and Stacks
Clinics rarely prescribe a single peptide in isolation. These are the protocol patterns that recur across the source material, grouped by goal.
Oct 2, 2026What Is Peptide Therapy? A Plain-English Foundation
Peptide therapy sits in an awkward place: a handful of peptides are ordinary FDA-approved medicines, while most of the molecules discussed online are unapproved research compounds. This chapter separates the two and gives you the vocabulary used throughout this guide.
