Five lessons before your first vial

The whole beginner course, on this page, free and unlocked. Read it top to bottom in about ten minutes and you'll avoid the four mistakes almost everyone makes: wrong water, wrong concentration, misread syringe, and no record of what happened.

1. Lesson 1

   What you actually bought

   A peptide vial is a freeze-dried powder — usually 5 to 30 mg of it — sealed under vacuum. It is not ready to use. Nothing in the vial is measured in "units"; the units on your syringe are a volume scale, not a dose.

   Peptides are short chains of amino acids that signal the body to do something it already knows how to do: repair tissue, release growth hormone, blunt appetite. That's why dosing is small and consistency matters more than heroic amounts.

   Takeaway: Powder in the vial. Water makes it usable. Units measure volume, not milligrams.

2. Lesson 2

   Mixing (reconstitution) without guessing

   You add bacteriostatic water — not sterile water, not saline — down the inside wall of the vial, slowly, aimed at the glass rather than the powder. Never shake it. Swirl gently or let it sit until it goes clear.

   How much water you add sets your concentration, and concentration is what decides how many units you draw. 10 mg of powder in 2 mL of water is 5 mg per mL. Add 1 mL instead and the same vial is twice as strong, so every dose becomes half as many units.

   Pick a round number of milliliters so the math is easy, write it on the vial with a marker, and keep that same ratio for the whole vial.

   Takeaway: Water volume decides concentration. Write it on the vial the day you mix it.

3. Lesson 3

   Reading a U-100 insulin syringe

   A 1 mL U-100 syringe is marked 0 to 100. Those 100 marks are 1 mL total, so 100 units = 1 mL, 50 units = 0.5 mL, 10 units = 0.1 mL. That is the entire conversion.

   So the question is only ever: how many mL is my dose, times 100. If your vial is 5 mg/mL and your dose is 250 mcg (0.25 mg), the dose is 0.05 mL — 5 units on the barrel.

   Half-mL syringes have the same 100-unit scale compressed differently; check the barrel print before you assume.

   Takeaway: 100 units = 1 mL. Convert the dose to mL, multiply by 100, draw that line.

4. Lesson 4

   Dosing, timing and not overdoing it

   Start at the low end of the commonly reported range for your compound and hold there for at least a week before changing anything. Most bad first experiences are dose escalation, not the peptide.

   Rotate injection sites so you're not hitting the same square inch repeatedly. Subcutaneous injections go into the fat layer — abdomen, love handles, thigh — at a shallow angle with a short insulin needle.

   Reconstituted vials live in the fridge, protected from light, and generally stay good for roughly four weeks. Unmixed powder keeps far longer, and the freezer is fine for long-term storage of powder.

   Takeaway: Low dose, one variable at a time, refrigerate after mixing, rotate sites.

5. Lesson 5

   Knowing whether it worked

   Decide before you start what would count as success, and how you'd measure it: pain score, waist measurement, morning weight, sleep quality, range of motion. Write it down on day zero.

   Log each dose with the date, the amount and the site. Two months later, memory is worthless and the log is the only honest record you have.

   Change one thing at a time. If you start three compounds in the same week, you learn nothing about any of them.

   Takeaway: Baseline first, log every dose, change one variable at a time.
