A Neutralizing Prolactin Receptor Antibody Whose In Vivo Application Mimics the Phenotype of Female Prolactin Receptor-Deficient Mice

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.

Hmi115, a prolactin receptor blocker, showed promise for hair growth, but results from Phase 2 trials have not been published. ABS-201, an AI-based analog, is expected to begin trials in December 2025, while commercialization of treatments like PP-405 is anticipated around 2027.

ABS-201 shows promise for male hair regrowth by blocking the prolactin receptor, with higher expected efficacy than current treatments. The discussion also covers dosing differences between macaques and humans for hmi115, highlighting a significant dosage disparity.

The conversation discusses using P5P (Vitamin B6) supplements to reduce elevated Prolactin levels and concerns about its potential effect on increasing DHT levels. The user is not currently using finasteride or any anti-androgens.

High prolactin levels may contribute to hair loss, and some users suggest supplements like mucuna pruriens, vitamin B6, vitamin E, L-Tyrosine, L-Theanine, DIM, and Zinc to lower prolactin. Lifestyle changes to increase dopamine, such as reducing screen time and stress, are also recommended.
