Independent peptide science
What's known, what isn't, and what changed.
Source-linked research, trial tracking and regulatory status for peptides — every claim cited, every evidence level shown, nothing for sale.
Start here
A peptide is a short chain of amino acids.
Each bead is an amino acid; the backbone joins them with peptide bonds, and every chain has a start (N-terminus) and an end (C-terminus). Longer chains fold into proteins. That is the whole idea — the rest is detail.

How we label evidence
One ladder, on every page.
Every claim is tagged with the strongest evidence behind it. Evidence and legal status are shown separately, because strong animal data is not approval — and approval for one use is not evidence for another.
Weakest to strongest. Hover a level to see what it means.
Instruments
Calculators that show their work
Amount ÷ final volume
Concentration calculator
Work out the concentration of a solution from a documented amount of substance and the final total volume.
5 mg in 2 mL
= 2.5 mg/mL
Amount ÷ concentration
Prescribed amount to volume
Convert an amount your clinician has already prescribed into a volume, using the concentration on the dispensed product's label.
250 mcg at 2.5 mg/mL
= 0.1 mL
Mass · volume · concentration
Unit converter
Convert between mcg, mg and g; µL, mL, L and U-100 syringe markings; and common concentration units.
0.25 mL on a U-100 syringe
= 25 units
Educational, fictional examples
How weight-based formulas work
See the arithmetic behind per-kilogram formulas using fictional numbers. Not for working out real doses.
2 mg/kg × 30 kg (fictional)
= 60 mg
Arithmetic only. The tools never suggest an amount of any substance.
