Side-by-Side Comparison

Aspect	BPC-157	Cortexin
Dose Range	250 mcg–500 mcg	10 mg–20 mg
Frequency	2x daily	1x daily
Cycle Length	4–6 weeks	1–2 weeks
Route	subcutaneous	intramuscular
Mechanism	BPC-157 works through multiple pathways including upregulation of growth factor expression, nitric oxide system modulation, and promotion of angiogenesis. It enhances tendon-to-bone healing and supports the formation of new blood vessels.	Contains a mixture of neuropeptides and amino acids that support neuronal metabolism, provide neuroprotection, and enhance synaptic transmission. Specific mechanisms not fully characterized.
Typical Dosage	Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied.	Clinical protocols: 10mg intramuscularly once daily for 10-20 days. May be repeated after 3-6 month interval.
Administration	Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable.	Intramuscular injection. Comes as lyophilized powder requiring reconstitution. Treatment given in courses rather than continuously.
Side Effects	Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses.	Generally well-tolerated. May cause injection site reactions or mild allergic responses in sensitive individuals.
