    TLDR 5-Aminolevulinic acid can help chicken sperm move better at the right amount.
    The study found that 5-Aminolevulinic acid (5-ALA) significantly improved chicken sperm motility. The optimal concentration was found to be 0.1 mM, beyond which the motility started to decrease. The addition of 0.05 mM 5-ALA increased various aspects of sperm motility, including progressive motility, linearity, average path velocity, curvilinear velocity, straight-line velocity, and the wobble. It also increased sperm mitochondrial membrane depolarization, which is thought to utilize ATP for enhancing sperm movement. However, 5-ALA treatment decreased sperm ATP levels. The study suggests that 5-ALA could potentially be used to enhance sperm motility in chickens, but the concentration needs to be carefully controlled.

      A user shared their 5-month hair transplant progress, having undergone a procedure with 4100 grafts at MedBlue in Istanbul for $3,600. They started taking oral minoxidil and finasteride daily after the transplant and use topical minoxidil with microneedling every two weeks, reporting positive results and no unwanted hair growth.

      The user experienced significant hair regrowth after switching from finasteride to dutasteride and from topical to oral minoxidil, despite some patchiness along the hairline. The user reduced the oral minoxidil dose due to low blood pressure concerns.

      The user is happy with hair regrowth after 5 months using topical minoxidil twice daily, oral finasteride once daily, derma stamping weekly, and Watermans shampoo. They noticed darker hair and stopped using creatine, suspecting it worsened hair loss.

      The user switched from finasteride to dutasteride, taking 0.5 mg oral dutasteride and 2.5 mg oral minoxidil daily, and reported significant hair regrowth with no side effects. The user experienced a shedding phase lasting a bit over a month after switching to dutasteride.
