One solution, fixed ratio
A blend vial is a single solution. Whatever volume you draw contains both peptides in the exact ratio the pharmacy mixed — you steer only the lead dose, the second follows automatically.
That is why the calculator asks for both amounts: it converts your lead dose into units, then reports the passenger dose riding along in the same draw.
When the label gives one number
Some blends — CJC-1295 with ipamorelin is typical — are prescribed by total micrograms of the mix. Enter that total as the lead and set the second field to zero.
Blends come pre-combined by licensed pharmacies. This math explains your label; it does not endorse mixing products yourself.
