Disclaimer
What Health is for, what it is not for, and the lines we ask you not to cross when using it.
Educational content, not medical advice
Everything on this site is written for general education. It describes how molecules, organs, and body systems tend to behave in the typical human, at the level of published consensus or plausible mechanism. It is not tailored to you, your labs, your history, or your medications, and it is not a substitute for the judgment of a licensed healthcare provider who knows your situation.
If you are symptomatic, if you are considering a new medication or protocol, or if you are trying to interpret your own test results — talk to a clinician. Reading a page here is not the same thing as being evaluated.
Peptides, hormones, and controlled compounds
Many of the peptides and hormones discussed on this site are prescription-only medications in most jurisdictions, research chemicals not approved for human use, or controlled substances. Describing how a compound works is not an endorsement of using it, a recommendation to acquire it, and it is not a dosing protocol. Do not act on any mechanism, dose range, or cycle structure described here without a licensed clinician’s involvement. Laws differ by country and state; obtaining or using regulated compounds outside of medical supervision may be illegal where you live and can be genuinely dangerous.
Sexual and reproductive health
Topics covering sexual function, fertility, hormonal contraception, and related areas are for understanding the underlying biology. They are not diagnostic tools and cannot replace evaluation by a physician, urologist, gynecologist, or other qualified provider. If something is wrong — pain, unexpected bleeding, infertility, persistent dysfunction — please get seen in person.
Calculators provide estimates, not measurements
The calculators on this site (free testosterone, TDEE, and any others) use published equations applied to the numbers you enter. They produce estimates, not clinical measurements. Real assays, real labs, and real clinical interpretation are all more accurate and more nuanced. Use the calculators to get rough intuition, not as a decision-making instrument.
Accuracy and the review date
Content is reviewed by a human before publication, but medicine moves, and our understanding of any particular mechanism can shift with new evidence. Each topic shows its last-reviewed date. Older pages are more likely to have drifted.
No responsibility for decisions
By using this site, you accept that the authors, editors, and operators of Health are not responsible for any decision you make, any action you take, or any outcome that follows from something you read here. You are an adult, and you are responsible for your own healthcare choices. We write openly and directly on the assumption that you will treat the information like education, not like a prescription pad.
