Side-by-Side Comparison

Aspect	DSIP	TB-500
Dose Range	100 mcg–300 mcg	2 mg–2.5 mg
Frequency	1x daily	Less than daily
Cycle Length	1–6 weeks	4–8 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.	TB-500 promotes cell migration and differentiation, regulates actin (a cell-building protein), and reduces inflammation. It supports the formation of new blood vessels and wound healing.
Typical Dosage	Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically.	Research protocols typically use 2-2.5mg twice weekly during the loading phase, followed by maintenance dosing of 2mg every 2 weeks.
Administration	Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use.	Administered via subcutaneous or intramuscular injection. Some protocols suggest injection near injury sites.
Side Effects	May cause grogginess upon waking, vivid dreams, or temporary headaches.	May cause temporary fatigue, headache, or localized irritation at injection sites.
