Teriparatide Dosage Guide for Recovery & Repair

Teriparatide is a lab-made piece of parathyroid hormone that tells the body to build new bone. It's an FDA-approved prescription treatment for osteoporosis, given as a small daily injection, and its use over a lifetime is generally kept to about two years.

What is Teriparatide?

Teriparatide is an FDA-approved medication, sold as Forteo or Bonsity, made from a fragment of natural human parathyroid hormone. It works by stimulating the body to build new bone, which increases bone density and lowers the risk of fractures. It's approved for people with osteoporosis, including postmenopausal women, certain men, and people whose bone loss was caused by long-term steroid use.

Healing

Research targets include tissue repair, wound healing, and recovery from injury.

How Does Teriparatide Work?

It attaches to a receptor found on bone-building cells, switching on growth-supporting signals and a pathway (Wnt) that favors building new bone. Giving it in short daily bursts, rather than continuously, is what tips the balance toward building bone instead of breaking it down.

How to reconstitute Teriparatide

View guide

The materials you'll need and step-by-step instructions for safely mixing Teriparatide with bacteriostatic water.

Materials needed

Your Teriparatide vial (lyophilized)

Alcohol swabs

Bacteriostatic sterile water

3 mL syringes (Luer Lock tip)

25G or 27G needles (Luer Lock). Other gauges may also be acceptable.

Sharps container (optional)

1

Remove the caps

Remove the caps from both your Teriparatide vial and your bacteriostatic water vial.
2

Sanitize the rubber stoppers

Wipe down the rubber stoppers on both vials with alcohol swabs and let them dry for about 3 minutes.
3

Attach the needle

Take your 3 mL syringe and needle. Twist the needle's plastic hub into the Luer Lock tip on the syringe to secure it.
4

Draw the bac water

Pull back on the plunger to draw your desired volume of bacteriostatic water. If you overfill, just push the excess back in until you reach the right marker on the syringe.

How much bac water? Teriparatide typically comes in a 1 mg vial. We recommend 1 mL of bacteriostatic water, though anywhere between 1 mL and 3 mL is acceptable. For larger vials you can use up to 5 mL — more bac water makes microdosing easier, but insulin needles usually max out at 1 mL per injection. That means a lot of bac water might force you into multiple injections to hit your target dose. Unless you're microdosing, 2 mL per vial is a solid rule of thumb.
5

Insert the needle into the Teriparatide vial

With the bac water in your syringe, insert the needle into the Teriparatide vial at a slight angle to avoid pressure buildup.

Use a thin needle: Stick to 25G or higher to avoid damaging the rubber stopper. Higher gauge means a thinner needle.
6

Release the water gently

Let the water run gently down the side of the vial. Don't inject it forcefully.

Heads up: Sometimes the plunger pushes itself in as soon as the needle enters the vial. Hold the plunger back so you have full control over how fast the bac water enters.
7

Swirl to dissolve

Avoid shaking. Gently swirl, flip, and roll the vial to dissolve the powder.

Be patient: This usually takes 2 to 5 minutes of consistent swirling, mixing in a circular motion, and gently flipping the vial up and down. The water needs to run through the powder many times to fully dissolve it. Don't shake or get aggressive with it.
8

Check for full dissolution

The solution should be clear with no visible particles. If it's cloudy or clumpy, wait a minute and repeat the swirling step.
9

Cap, dispose, and store

Once you're done, cap the needle and dispose of it (ideally in a sharps container). Store the reconstituted Teriparatide vial in the fridge whenever it's not in use. It will stay good for approximately 30 days.

How to Store Teriparatide

Keep the pre-filled pen in the fridge and never freeze it — discard it 28 days after you first use it. It can be kept at room temperature for up to a day and a half if you're traveling.

Pre-Filled Pen Storage

Refrigerate at 2–8°C; do not freeze.

Usage Window

Discard 28 days after first use.

Travel Notes

May be kept at room temperature (up to 25°C) for up to 36 hours.

What Are the Benefits of Teriparatide?

What research says it may help with, and how it works in the body.

osteoporosis fdaapproved

It's FDA-approved for women who have osteoporosis and are at high risk of breaking a bone.

It's FDA-approved for men and women whose osteoporosis was caused by long-term use of corticosteroid medications.

It's FDA-approved for men with osteoporosis, including cases linked to low testosterone, who are at high risk of fracture.

bone health research

Researchers are studying whether it can speed up the healing of broken bones and general bone repair.

It's being studied for helping regrow jawbone in dental treatments.

How Long Should a Teriparatide Cycle Last?

This breaks down how long a typical Teriparatide cycle runs and what research suggests happens at each stage. Research shows that staying on a peptide continuously, without a break, may make it less effective over time.

That's why most research protocols build in a break between cycles, often called a washout period, to let the body reset before starting again.

Month 1-3
Bone formation begins; spine BMD increases
Month 3-6
Continued bone density improvements
Month 6-12
5-9% spine BMD increase; fracture risk reduction
Week 0-0
Maximum benefits achieved; transition to maintenance
