Clascoterone in Winlevi, a topical AR antagonist, is being re-examined due to concerns about HPA axis suppression in adolescents, but it's unlikely to be banned for adult use in androgenetic alopecia (AGA). The European Medicines Agency recommended refusing Winlevi for acne vulgaris, but this may not affect Breezula's approval for AGA.
The conversation discusses the mechanism of action of alfatradiol (17 alpha estradiol) in treating hair loss. It explores theories that it either inhibits 5 alpha reductase to prevent T->DHT conversion or aromatizes scalp T into 17-alpha-estradiol to save hair.
An increase in libido associated with the use of Pyri, and a discussion about how it may be working comparably to other hair loss treatments such as RU58841, Finasteride and Minoxidil.
RU58841 is used topically to prevent hair loss by blocking DHT, with suggestions to drink grapefruit juice, take breaks, avoid microneedling, and use lower concentrations to reduce side effects. Users discuss applying it at night to minimize systemic absorption.
The user shared their experience with CB-03-01 (Breezula/Clascoterone) for hair loss, noting reduced shedding and improved hair appearance but experiencing significant sleep disturbances and low energy due to HPA axis suppression. They decided to stop using it due to these side effects and are waiting for GT20029 as an alternative.
