Collagen Peptides- 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.
- Collagen peptides are short-chain amino acid sequences produced by enzymatic hydrolysis of whole collagen (typically bovine or marine). They serve as bioactive signals that stimulate fibroblasts and chondrocytes to produce new collagen, elastin, and cartilage matrix, supporting skin, joint, bone, and gut health.
- Half-Life
- ~2–4 minutes (extremely short); pulsatile dosing required to avoid desensitization
- N/A — food-derived; absorbed peptides circulate for hours, depot accumulation in tissues
- Admin Route
- SubQ, Intranasal
- Oral
