How many units of Cagrilintide should I draw?

It depends on your vial size, BAC water, and dose. For a 5mg vial with 2mL BAC water, a beginner dose of 500mcg is typically 20 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to Cagrilintide?

The standard amount is 2mL of bacteriostatic water for a 5mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a Cagrilintide vial last?

At a beginner dose of 500mcg weekly, a 5mg vial lasts about 10 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for Cagrilintide?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

Cagrilintide Pharmacokinetics

Pharmacokinetics — Active Dose Over Time

t½ = ~7 days

After 1 half-life (7d): 50% remainsAfter 2 half-lives (14d): 25% remainsAfter 3 half-lives (21d): 12.5% remains

At a 1.2mg dose: 50% = 600mcg remaining after 7d. Recommended frequency: Weekly.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

Note: Long-acting amylin analog. Different mechanism than GLP-1 agonists. Titrate slowly from 0.5mg. Can be combined with semaglutide (CagriSema).

About Cagrilintide

Cagrilintide is a long-acting amylin receptor agonist that works through a completely different pathway than GLP-1 drugs like semaglutide. Amylin is naturally released by the pancreas after meals to promote satiety. Cagrilintide mimics this effect, reducing cravings and slowing gastric emptying. It's being studied both alone and in combination with semaglutide (CagriSema) for enhanced weight loss.
