BPC-157 vs Follistatin

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

BPC-157

Body Protection Compound-157 is a synthetic peptide derived from a protein found in human gastric juice. It has shown remarkable healing properties in research studies.

Follistatin

Follistatin is a glycoprotein that inhibits myostatin, the protein responsible for limiting muscle growth. By blocking myostatin, follistatin can theoretically allow for increased muscle development beyond natural limits.

Side-by-Side Comparison

Aspect	BPC-157	Follistatin
Dose Range	250 mcg–500 mcg	50 mcg–100 mcg
Frequency	2x daily	1x daily
Cycle Length	4–6 weeks	2–4 weeks
Route	subcutaneous	subcutaneous
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.	Binds to and neutralizes myostatin and activin, both of which are negative regulators of muscle mass. This removes the natural brake on muscle growth, allowing for enhanced hypertrophy.
Typical Dosage	Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied.	Research protocols typically use 100-300mcg daily, though optimal dosing is not well established. Gene therapy approaches have also been studied.
Administration	Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable.	Subcutaneous injection. Different isoforms exist (FS344, FS315) with varying properties. Requires careful sourcing due to complexity.
Side Effects	Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses.	Limited human data. Theoretical concerns about effects on other organs where activin signaling is important.
