DSIP vs MGF (Mechano Growth Factor)

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

DSIP

Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.

MGF (Mechano Growth Factor)

MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is produced locally in muscle tissue in response to mechanical stress. The non-PEGylated form has a very short half-life.

Side-by-Side Comparison

Aspect	DSIP	MGF (Mechano Growth Factor)
Dose Range	100 mcg–300 mcg	400 mcg–1.2 mg
Frequency	1x daily	Less than daily
Cycle Length	1–6 weeks	4–6 weeks
Route	subcutaneous	intramuscular
Mechanism	Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties.	Activates muscle satellite cells (stem cells) and promotes their proliferation without differentiation, priming them for fusion with existing muscle fibers during repair and growth.
Typical Dosage	Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically.	Due to extremely short half-life (minutes), typical protocols use 100-200mcg injected directly into target muscles immediately post-workout.
Administration	Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use.	Intramuscular injection into trained muscles within minutes of workout completion. Must be used immediately after reconstitution due to instability.
Side Effects	May cause grogginess upon waking, vivid dreams, or temporary headaches.	Injection site soreness, potential hypoglycemia, localized swelling. Short half-life limits systemic effects.
