Day 1: What Are Peptides?
Peptides are short chains of amino acids linked by peptide bonds. While proteins contain 50 or more amino acids, peptides are generally defined as chains of 2 to 50 amino acids. This distinction matters because their smaller size gives peptides unique pharmacokinetic properties — they can be absorbed, distributed, and cleared from the body differently than larger proteins.
How Peptides Work
Every cell in the human body communicates through signaling molecules. Peptides act as these messengers, binding to specific receptors on cell surfaces to trigger downstream biological effects. When a peptide binds its receptor, it initiates a cascade of intracellular events — gene expression changes, enzyme activation, or ion channel modulation. The specificity of this binding is what makes peptides such precise research tools.
Endogenous vs. Exogenous
Your body already produces hundreds of peptides naturally (endogenous). Insulin, oxytocin, and growth hormone-releasing hormone (GHRH) are all peptides. Research peptides (exogenous) are synthesized to mimic, enhance, or modulate these natural signaling pathways. Solid-phase peptide synthesis (SPPS) allows researchers to create sequences with high purity and consistency.
Major Categories
- GLP-1 receptor agonists — incretin mimetics that influence glucose metabolism and appetite signaling (Semaglutide, Tirzepatide, Retatrutide)
- Growth hormone secretagogues — stimulate the pituitary to release GH through GHRH or ghrelin pathways (Ipamorelin, CJC-1295, Tesamorelin)
- Tissue repair peptides — modulate inflammatory and regenerative pathways in connective tissue, muscle, and gut lining (BPC-157, TB-500)
- Copper peptides — metal-peptide complexes involved in wound healing, collagen synthesis, and antioxidant defense (GHK-Cu)
- Melanocortin peptides — act on MC receptors influencing pigmentation and sexual function (PT-141, Melanotan II)
Why Sequence Matters
A single amino acid substitution can completely change a peptide's receptor affinity, half-life, and biological activity. This is why purity testing (HPLC) and identity verification (mass spectrometry) are non-negotiable. In tomorrow's lesson, we will cover exactly how to reconstitute lyophilized peptides and calculate accurate dosing — the foundation for any meaningful research protocol.

Frequently Asked Questions
What does the 7-day course cover?
The course covers peptide fundamentals across seven daily lessons: Day 1 introduces amino acid chains and compound categories. Day 2 covers reconstitution and dosing math. Day 3 explores GLP-1 peptides (semaglutide, tirzepatide, retatrutide). Day 4 covers growth hormone secretagogues. Day 5 covers recovery peptides (BPC-157, TB-500, GHK-Cu). Day 6 teaches stacking and protocol design. Day 7 covers vendor selection, COA reading, and quality standards.
Is the course free?
Yes, 100% free. No credit card, no trial period, no upsells. You receive seven emails over seven days. Each lesson is a 5-8 minute read designed to be concise and actionable. Your email is used solely to deliver the course and optional weekly newsletter, and you can unsubscribe with one click at any time.
Do I need prior knowledge?
No. Day 1 starts with the fundamentals of what peptides are and how they work. The course builds progressively from basic concepts to advanced topics like stacking and protocol design. Whether you are brand new to peptide research or looking to fill knowledge gaps, the course is structured for all levels.
