How to use a peptide pen
Watch the general mechanics, then confirm the exact device, needle, priming method, hold time, storage conditions and click scale for the pen in your hand.
Dosing reference
Find the amount, then understand the context.
The Dosing Guide shows common research reference ranges and schedules. The individual peptide pages explain where each figure comes from, which formulation it applies to and what remains uncertain.
01What are peptides, and where should a beginner start?
Peptides are short chains of amino acids that can act as signals, medicines or research tools. The best starting point depends on whether you want a basic explanation, information about a specific peptide or a structured learning path.
02Where can I find peptide doses and reference schedules?
The Dosing Guide brings the Pep Report reference ranges and schedules together in one place. Each peptide profile also explains the evidence, formulation and limitations behind its reference amount. These are educational research references, not individualized recommendations.
03How do I calculate a vial or pen amount?
Choose the calculator that matches the product in front of you. Vials require the total peptide amount, liquid volume and target amount. Pens require the exact device type, cartridge strength and click or dose-selector system. The calculator performs arithmetic only and does not choose a dose.
04What is the difference between mg, mcg, mL and syringe units?
Milligrams and micrograms measure mass. Milliliters measure liquid volume. Syringe units are markings on a particular syringe. They are not interchangeable, and confusing them can produce serious dosing errors.
05How should peptides, pens and reconstituted vials be stored?
Storage belongs to the exact formulation. A finished pen, a dry vial and a reconstituted vial can have different temperature, light and usable-life limits even when they contain the same peptide. Start with the general framework, then check the detailed storage section on the relevant peptide profile.
06How do I know whether a peptide claim is supported by good research?
Look at the evidence type, study design, population, formulation, endpoint and whether the result has been replicated. The Research Papers section gives plain-English summaries and direct links to the full original studies and official sources.
07How do I evaluate a peptide supplier?
Do not judge a supplier by purity language alone. Check identity, quantity, batch matching, laboratory provenance, microbiology where relevant, manufacturing transparency, storage, shipping and whether the evidence can be tied to the product being sold.
08I know my goal, but I do not know which peptide pages are relevant. What should I do?
Use the Personalised Guide. It asks about your goals, current knowledge and preferred depth, then builds a path through the most relevant peptide profiles, Academy lessons, research and practical tools.
One important distinction
Strength is not the same thing as dose.
A 20 mg vial tells you how much peptide is in the vial. A dose is the amount taken at one time. Concentration and syringe units are separate calculations.
