Side-by-Side Comparison

Aspect	DSIP	Teriparatide
Dose Range	100 mcg–300 mcg	20 mcg
Frequency	1x daily	1x daily
Cycle Length	1–6 weeks	52–104 weeks
Route	subcutaneous	subcutaneous
Mechanism	Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties.	Intermittent PTH exposure paradoxically stimulates osteoblasts more than osteoclasts, resulting in net bone formation. Continuous exposure would cause bone loss, but pulsatile dosing builds bone.
Typical Dosage	Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically.	20mcg subcutaneously once daily. Maximum treatment duration of 2 years due to theoretical osteosarcoma risk from rat studies.
Administration	Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use.	Subcutaneous injection in thigh or abdomen once daily. Delivered via multi-dose pen. Should sit or lie down after injection due to orthostatic hypotension risk.
Side Effects	May cause grogginess upon waking, vivid dreams, or temporary headaches.	Orthostatic hypotension, leg cramps, nausea, dizziness, headache, and injection site reactions. Transient hypercalcemia possible.
