Reported ranges, live reconstitution calculators, half-life, storage and primary-literature citations for 40 research compounds. Every number traceable, every citation checked.
Three steps. Once you see them, you never need a printed chart again.
Peptide dosage confuses people because two different numbers get called "dose": the amount of peptide you want, and the amount of liquid you draw. They are only related through one value, and that value is set by you when you reconstitute the vial.
Divide the peptide in the vial by the bacteriostatic water you added. A 10 mg vial reconstituted with 2 mL of water gives 5 mg/mL. Add 5 mL instead and the same vial gives 2 mg/mL. The peptide quantity never changed, only how spread out it is.
Divide your target amount by the concentration. At 5 mg/mL, a 250 mcg (0.25 mg) target means drawing 0.05 mL.
A U-100 insulin syringe is marked so that 100 units equals 1 mL. Multiply millilitres by 100, and 0.05 mL becomes the 5-unit mark. That is the number you actually read on the barrel.
Concentration first (mg in vial ÷ mL of water = mg/mL), then draw volume (target ÷ concentration = mL), then syringe units (mL × 100 on a U-100 syringe). The calculator on every compound page does all three and shows the working.
A chart maps vial strength and water volume to concentration and syringe units so you can read a value directly. The catch is that the right chart depends entirely on how much water was added, which is why a live calculator beats a fixed printed chart.
There is no single right answer. Laboratory protocols commonly use between 1 mL and 5 mL. More water makes each draw larger and easier to measure; less water concentrates it. Pick the volume that puts your typical draw in a readable range on the syringe.
No. Every figure summarizes what published literature and laboratory protocols document. Nothing here is a recommendation, medical advice, or an instruction for human use. All compounds referenced are for laboratory research use only.
Because a number without a source is just a claim. Every citation in this library is checked programmatically against the NCBI PubMed database, and the titles shown are the official indexed titles rather than paraphrases. If a reference cannot be verified, it does not appear.
