GlossaryCYP17A1

enzyme crucial for steroid hormone production

CYP17A1, also known as Cytochrome P450 17A1, is an enzyme that plays a crucial role in the production of steroid hormones. It is involved in the conversion of pregnenolone and progesterone into their 17-alpha-hydroxylated products, which are precursors for androgens and estrogens. This enzyme is essential for the synthesis of hormones that regulate various bodily functions, including metabolism, immune response, and sexual development.

community NootBro Recommendations… How Do We Feel

in Research/Science 9 upvotes 5 months ago

The conversation is about hair loss treatments, specifically a stack including topical Ashwagandha, Copper Peptide, Gotu Kola, Ketoconazole, and PDA. One user found Topical and Sub-Q GHK-CU effective.

community Is Keto shampoo 2% even worth starting?

in Ketoconazole 44 upvotes 2 months ago

Ketoconazole shampoo is primarily for scalp health and reducing inflammation, not hair regrowth. Combining ketoconazole with finasteride can yield similar results to using minoxidil and finasteride together.

community My hairloss stack, progress pics soon maybe for 1 year RU

in Technology 49 upvotes 1 year ago

The conversation is about a user's hair loss treatment routine, which includes RU58841 for 9 months and Dutasteride for 6 months, with other unspecified treatments considered extra. One user inquired about the source of RU58841.
