How do I calculate peptide concentration after adding water?

Divide the amount in the vial by the volume of water you added. A 10 mg vial mixed with 2 mL gives 10 ÷ 2 = 5 mg/mL, which is the same as 5,000 mcg/mL.

How many units are in 1 mL on a U-100 syringe?

A U-100 insulin syringe is marked so that 100 units equal 1 mL. Each unit is 0.01 mL, so 0.25 mL reads as 25 units.

How do I convert mg to mcg?

Multiply milligrams by 1,000. 1 mg = 1,000 mcg, so 0.25 mg = 250 mcg. To go back, divide mcg by 1,000.

Can I convert units on the syringe back to an amount?

Yes. Divide the units by 100 to get mL, then multiply by the concentration. 20 units = 0.20 mL; at 5 mg/mL that holds 1 mg. The calculator does this when you type units into the units box.

Does adding more water change how much is in the vial?

No. The total in the vial stays the same. More water lowers the concentration, so the same amount takes up more volume and more units on the syringe.

Why is IU treated differently from mg?

IU measures biological activity, not weight, so there is no universal IU-to-mg rule. The calculator uses the IU count printed on your own vial label instead of guessing.

Does PeptideWhiz suggest doses?

No. PeptideWhiz never suggests or recommends an amount. Every number comes from you, and the tool only does the arithmetic. It is not medical advice.

Do I need an account to use the calculator?

No. The calculator is free and works without an account. An account only lets you save results to your stack and tracker.

About Abaloparatide

Abaloparatide is a 34-amino-acid analogue of parathyroid hormone-related protein. It acts on the same PTH1 receptor as teriparatide but favours a receptor state that researchers link to bone formation with less calcium release.

Research status

Abaloparatide is FDA-approved as a prescription medicine (Tymlos) for osteoporosis in postmenopausal women and in men at high fracture risk. The ACTIVE and ATOM trials below are its main published evidence.

How the math works for any vial (concentration, U-100 units, mg and mcg) is explained step by step on the main peptide reconstitution calculator page. Read the full What is Abaloparatide? guide for mechanism, trials and conditions researched.

What published studies used

Research record, not a recommendation or protocol

These are published human trials of Abaloparatide from the PeptideWhiz study library. The last column quotes each study’s PubMed abstract word for word, so it shows what that study reported giving its participants under medical supervision. It is not advice, and the calculator never fills these numbers in on its own: you can copy one only by tapping its button and confirming.

Abaloparatide calculator FAQ

What is Abaloparatide?

Abaloparatide is a parathyroid hormone-related protein (PTHrP) analogue. Abaloparatide is a 34-amino-acid analogue of parathyroid hormone-related protein.

Is Abaloparatide approved?

Does this page suggest a Abaloparatide dose?

No. The calculator dose field starts empty and PeptideWhiz never suggests, recommends or calculates an amount for anyone. The study table is a research record of what published trials reported, not a recommendation or protocol.

Where do the study numbers on this page come from?

Each row quotes the abstract of a published human trial (5 trials, 2015 to 2022) word for word, as indexed in PubMed, with a link to the PubMed record. Nothing is rounded, combined or converted.

How does the calculator work with a Abaloparatide vial?

Pick Abaloparatide in step 1 if you want it on your result card, then enter the vial amount printed on your own label and the water volume actually added. The tool divides one by the other for concentration and shows the matching U-100 syringe units for an amount you type. Pens and pre-filled syringes are already in liquid form and are not reconstituted.
