How to Choose a Peptide Therapy Clinic
Provider quality varies enormously in this field, and the differences that matter — sourcing, testing, licensing, screening — are rarely visible on a clinic's website. This chapter is a vetting checklist.
Oct 2, 2026Reconstitution, Administration and Handling
Most peptides ship as lyophilised powder and must be reconstituted before injection. The arithmetic and handling rules below are the same regardless of which peptide you are working with.
Oct 2, 2026Cost, Insurance and Access: What Peptide Therapy Actually Costs
Price is driven less by the molecule and more by whether a peptide is FDA-approved (insurable) or research-grade (cash-pay). This chapter breaks down the cost structure and lists reported price points.
Oct 2, 2026What Results to Expect, and When
Timelines vary by peptide class: GLP-1 receptor agonists produce measurable changes within weeks, while reparative and longevity peptides are described in months. This chapter collects the timelines and the factors that reliably change outcomes.
Oct 2, 2026Side Effects Across Peptides: Patterns, Routes and Management
Side effect profiles cluster more by route and dose than by molecule. Injection-site reactions, gastrointestinal effects and dose-dependent responses recur across nearly every peptide in this guide; the peptide-specific differences are listed at the end.
Oct 2, 2026Dosing Principles: How Peptide Protocols Are Actually Built
There is no official dose for most of the peptides in this guide — the numbers in circulation come from animal studies, practitioner surveys and vendor convention. This chapter explains how those numbers are derived, how titration works, and what the reported ranges are for every peptide covered here.
Oct 2, 2026FDA Compounding Decisions and the 2026 Peptide Rulemaking
Regulatory status is not static. Between 2022 and 2026 the FDA moved several peptides between Category 1, Category 2 and removal from the bulk drug substance list. This chapter tracks the decisions that changed what clinics can legally provide.
Oct 2, 2026The Legal and Regulatory Landscape for Peptides in the United States
FDA approval, 503A/503B compounding eligibility, DEA scheduling and state law are four separate questions, and a peptide can be legal on three and prohibited on the fourth. This chapter explains the framework, then lists where each peptide in this guide currently stands.
Oct 2, 2026Is Peptide Therapy Safe? Side Effects, Interactions and Long-Term Data
Safety questions dominate peptide therapy, and for good reason: most peptides discussed in this guide have no completed human safety database. This chapter consolidates the safety picture — common effects, route-specific risks, interactions, dose-dependent effects and what long-term data actually exists.
Oct 2, 2026How Peptides Work: Mechanisms of Action by Class
Peptides are signalling molecules, not nutrients. What they do depends almost entirely on which receptor they bind and how long they survive in the bloodstream. This chapter walks through the mechanisms behind the main peptide classes covered in this guide.
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.
