Research dosing range: 20 mcg daily (subcutaneous)

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Osteoporosis (Severe)

20 mcg1× daily

Duration

Up to 2 years

Administer subcutaneously in the thigh or abdomen. Rotate injection sites. Supplement with calcium and vitamin D if dietary intake is insufficient. Treatment beyond 2 years is not recommended due to potential risk.

Varies (10-20 mcg)1× daily

Duration

Variable

Used off-label in some cases to manage hypocalcemia. Requires careful monitoring of calcium and phosphate levels. Dosage adjustments are based on individual patient response and biochemical parameters. Not FDA-approved for this indication. Consider consultation with an endocrinologist.

Timing & Frequency

Teriparatide should be administered once daily at approximately the same time each day. Adherence to the daily injection schedule is important. Can be injected at any time of day, but consistency is recommended.

Cycle Guidance

Treatment duration is strictly limited to a maximum of 2 years (24 months) due to concerns about increased risk of osteosarcoma based on preclinical studies in rats. Extended use beyond 2 years is not recommended.
