community Did anybody use beta sisterol for hair loss? I saw in many articles in the internet that said that beta sisterol blocks dht by inhibiting 5a reductase type 2 enzyme and some reviews of people who said that it worked better than saw palmetto in terms of stoping hair loss and helping prostate.

in Research/Science 9 upvotes 3 years ago

Beta-sitosterol may inhibit 5-alpha reductase type 2 enzyme, potentially reducing DHT levels and promoting hair growth, similar to finasteride but possibly with fewer side effects. Its effectiveness and side effects compared to other treatments like saw palmetto and finasteride remain uncertain due to limited research.

community ghk-cu is potent 5-ar inhibitor?

in Product 10 upvotes 2 years ago

GHK-Cu is a potent inhibitor of the type 1 5-alpha reductase enzyme in hair follicles, which may reduce hair loss without the side effects associated with type 2 5-alpha reductase inhibitors. The user previously experienced side effects with 5-alpha reductase inhibitors and is considering GHK-Cu as an alternative.

community FCE 28260: A Forgotten 5α-Reductase Inhibitor

in Research 330 upvotes 1 year ago

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

community Which Saw Palmetto is good for blocking 5 alpha reductase, Serenoa repens or Chamaerops humilis?

in Finasteride/Dutasteride 6 years ago

The conversation is about determining which type of Saw Palmetto, either Chamaerops humilis or Serenoa repens, is effective for inhibiting the 5 alpha reductase enzyme related to hair loss. Specific treatments mentioned are Minoxidil, finasteride, and RU58841.

community 5ar alpha reductase stimulation is different depending on whether it’s type 1 or 2

in Hair Systems 17 upvotes 3 years ago

The conversation discusses how different factors can stimulate type 1 and type 2 isoforms of 5-alpha reductase, which are enzymes linked to hair loss. Specific treatments mentioned include oral Dutasteride and topical Finasteride.
