GHK- Summary
- Enclomiphene is the trans-isomer of clomiphene citrate, a selective estrogen receptor modulator (SERM) that stimulates endogenous testosterone production by blocking estrogen negative feedback on the hypothalamus and pituitary. Unlike TRT, it restores testosterone while preserving or increasing sperm production and testicular volume.
- GHK is the natural tripeptide (Gly-His-Lys) released from human albumin that activates tissue remodeling, collagen synthesis, and anti-aging gene expression. The copper-free form is the biological signaling molecule; it chelates copper in tissue to form GHK-Cu but also has independent biological activity.
- Half-Life
- 5-7 days (long half-life; accumulates)
- Extremely short as free peptide; tissue binding extends local effects
- Admin Route
- Oral
- SubQ, Topical, Oral
