Plain-language summary
This study is a randomized, double-blind, placebo-controlled trial examining the effects of creatine monohydrate supplementation on androgens and hair loss in free-living adult males. Participants will complete 6 months of supplementation of 5 grams per day of creatine monohydrate while following their normal lifestyle practices. At baseline and six months after study initiation, participants will complete laboratory assessments. These assessments will include a standard blood draw for evaluation of total testosterone (T), free T, dihydrotestosterone (DHT), and DHT:T ratios in the blood, as well as global photography and questionnaires to evaluate hair loss. This study will examine the claim that creatine increases DHT concentrations and and DHT:T ratio, as well as provide novel data regarding whether creatine promotes hair loss.

Inclusion Criteria:
* Male between the ages of 18 and 35
* Weight of at least 110 pounds
* Generally healthy (defined as an absence of a disease or medical condition which could potentially be negatively influenced by study participation or confound study results)
* Low levels of habitual creatine consumption, defined as consuming an average of \<10 g/week of creatine from all supplemental sources within the three months prior to study initiation
* Willingness to report to baseline and final assessments with a similar haircut (i.e. willingness to replicate baseline haircut prior final assessment, to the best of his ability) and one that allows for evaluation of hair growth patterns (e.g., not a completely shaved head that disallows visualization of the hairline)
* Willingness to adhere to the supplementation protocol for the duration of the study (i.e., 6 months of daily supplementation with 5 grams per day of creatine monohydrate or placebo) and abstain from additional creatine supplement ingestion during this time.
* Willingness to abstain from any treatments related to hair loss or hair growth for the duration of the study
* Willingness to maintain normal practices regarding hair products (i.e. continue to use regular shampoo, conditioner, and other products over the duration of the study and abstain from switching products during the study if at all possible)

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
