Research peptide guides
Plain-English explanations of reconstitution, dosing, half-life, syringes, storage and stack design — the stuff a calculator alone won’t teach you. Free, no signup, written for first-time researchers.

If you’ve got a vial in your hand right now and you’re trying to work out how much to draw, jump straight to the dosage calculator — then come back here to learn the methodology behind it.
Open Peptide Dosage Calculator →Reconstitution 101
How to mix bacteriostatic water with a lyophilised peptide vial — the right ratio, the right technique, what not to do.
Bacteriostatic water
What BAC water is, why benzyl alcohol matters, and how to choose the right volume so your concentration matches your calculator.
Insulin syringe basics
U-100 units explained. How to pick the right gauge and length, how to read the barrel, and how a 30-unit draw becomes a mg dose.
Pen dosing format
The 3 mL / 300-click pen format demystified. Click counts to mg, why pens auto-prime, when a pen beats a vial.
Nasal spray basics
Selank and Semax: per-spray dose maths, reconstitution-to-sprayer workflow, technique, and the gotchas that catch most beginners.
Half-life & dosing frequency
Why BPC-157 is dosed daily but TB-500 can be once a week. Reading half-life numbers and translating them into a frequency.
Stack-building methodology
Why GLOW, KLOW and Wolverine are the stacks they are. How to combine compounds without doubling overlap.
Cycling & off periods
Why most research protocols cycle on/off. Tolerance, receptor downregulation, and what evidence says about washout windows.
Storage & shelf life
Refrigerator vs freezer, before vs after reconstitution, and how to tell when a peptide has gone past its useful window.
Injection-site rotation
Abdomen, thigh, deltoid: which sites work for which peptides, and a simple rotation pattern that avoids irritation.
Reading a COA
What a Certificate of Analysis actually proves, what to look for, and which red flags mean your vial isn’t what the label says.
