Invigor.
Highest concentration in the comparison (5mg/ml) — but 2ml = 10mg = $22/mg. Concentration means nothing if the vial is small.

THE VERDICT
Invigor's 5mg/ml concentration is the marketing hook — and it is a real clinical feature for patients who prefer smaller injection volumes. But concentration doesn't add milligrams. The 2ml vial contains 10mg regardless of how concentrated it is. At $22.00/mg with no volume pricing, Invigor is the most expensive sermorelin per milligram in this comparison. A patient dosing continuously through Invigor spends approximately $330 per month. The same patient on RespondWell's 30ml program spends approximately $100 per month.
