Peptide guides
Our guides will bring a subject together in one place, with clear explanations, compound comparisons, visual summaries and study links. Preview the first two outlines while the finished PDFs are in development.

See collection contentsFree reading by topic
These short reading sequences are free. Each starts with a useful idea, then connects lessons, profiles or a comparison in an order that helps explain the subject. The PDF previews above are separate products in development.
Metabolism & weight
Learn how the receptor targets differ, then read the semaglutide, tirzepatide and retatrutide trials. Pay attention to who entered each trial and what the comparison actually measured.
Recovery & repair
Start with the BPC-157 injury studies, then compare its research with TB-500. Finish with full-length thymosin β4 to see why a fragment and its parent peptide need separate accounts.
Skin & connective tissue
Learn what copper binding changes before reading the skin studies. The GHK and GHK-Cu profiles then explain which findings concern the peptide, its copper complex or a particular formulation.
Gut & inflammation
Read how laboratory and animal findings relate to human studies, then compare intestinal inflammation with barrier research. KPV and larazotide introduce those different approaches; BPC-157 adds a separate digestive research history.
Brain & cognition
Read Semax for neurological and imaging research, Selank for anxiety studies, and oxytocin for behavioral trials. The final lesson explains why a scan or a cell response is different from a measured change in symptoms.
Sleep & stress
Separate sleep stages, anxiety symptoms and sleep apnea before comparing these profiles. GHRP-6, Selank and tirzepatide investigate different questions; they are not three versions of a sleep treatment.
Immune system
Start with thymic biology, then read the disease-specific thymosin α1 trials and KPV inflammatory models. The lesson on study interpretation helps distinguish an immune marker from an outcome such as symptoms or survival.
Growth hormone
Learn receptor signaling, then compare CJC-1295 with DAC and modified GRF(1–29). Tesamorelin provides a different clinical example of why the exact material and studied condition matter.
Aging & longevity
Use the interpretation lesson to separate cell changes, animal lifespan results and human observations. Epitalon and Humanin then show how those different measurements appear in aging research.
Mitochondria & cellular energy
Read MOTS-c and Humanin for mitochondrial-derived signaling and endogenous measurements, then elamipretide for a separate mitochondrial drug program. These profiles connect cell biology to distinct experiments and clinical outcomes.
Sexual & reproductive health
Begin with the two kisspeptin forms to understand reproductive-hormone experiments and the IVF studies. Bremelanotide then introduces a different pathway and trials measuring sexual desire and related distress.
Understand blends and bioregulators
Read a blend through its ingredients
Begin with the BPC-157 and TB-500 comparison, then read GLOW and KLOW. Their profiles explain stated composition without treating ingredient studies as trials of the complete mixtures.
Read the exact bioregulator identity
Learn how a sequence defines a peptide, then read Epitalon. Its profile keeps the defined AEDG tetrapeptide separate from related gland extracts and their reports.
What the guides will add
Each finished guide will bring its subject into one PDF, with explained comparisons, visual summaries and direct study links. The contents page will show the covered compounds, edition and exact contents of a collection.
Pricing and purchase details will appear when the files and delivery are ready. The current collection preview covers the two focused guides; it does not promise every future title.
