BPC-157- Summary
- Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.
- BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in the stomach. It is one of the most extensively researched healing peptides, known for accelerating tissue repair, reducing inflammation, and protecting the gastrointestinal tract.
