About TherapyLog, and how its reference pages are written
TherapyLog is a TRT and peptide tracker. This page says who writes the reference content on this site, how claims are sourced and labelled, and where the limits are — so you can judge the rest of it.
Who writes this
TherapyLog is written, built and supported by Joel Gonzales, its founder. One person writes the software, writes the reference pages and answers the mail. If you send a bug report or a correction to hello@therapylog.app, he is who reads it.
Not a clinician. Joel Gonzales is not a physician, nurse practitioner, pharmacist or any other licensed clinician, and nothing on this site is written or reviewed by one. That is a disclosure, not a disclaimer to skim: it is the reason every page here cites its sources instead of asking you to take its word, and the reason every discussion of a side effect ends with taking the result to the clinician who prescribes for you. Adding a paid clinical reviewer is an intended upgrade, not something this site claims today.
Why the site exists
People run testosterone therapy and peptide protocols whether or not there is good information available to them, and much of what they can find is written either by someone selling a compound or by someone who has decided the practice should not exist. Neither produces a page that helps a person holding a vial at eleven at night.
TherapyLog's purpose is harm reduction. The app exists so that doses, bloodwork and symptoms get written down and can be shown to a doctor. The reference pages exist so that the arithmetic is right and the numbers on a lab report mean what the reader thinks they mean. Every side-effect pathway in the app and on this site ends the same way — take it to your prescribing clinician — because that is both the honest answer and the whole point.
That mission is also why TherapyLog is a web app rather than a store listing. Getting listed would mean cutting the compound and dosing information the people who use this actually rely on, and a tracker that omits what you are tracking is not a harm-reduction tool. It stays on the web, installable to your home screen, indefinitely.
Editorial policy
Every reference page on this site — the calculators under Tools and the lab-marker pages under Lab markers — follows the same rules.
Every page names its author and a review date
No anonymous reference content. Each page carries the byline above and the date it was last read end to end, not the date its template changed.
Claims cite primary literature or guideline documents
Where a page states something that is not a definition, it links the study, the guideline or the label it came from — not a secondary article summarising one. Where the evidence is thin, the page says the evidence is thin rather than rounding it up.
Evidence is labelled in three tiers
- Established clinical use — supported by guidelines, approved labelling or replicated human trials.
- Off-label or community practice — what people and some clinicians actually do, with the reasoning, clearly marked as not an approved indication.
- Animal-only or theoretical — a mechanism or a rodent study, and nothing more. A great deal of peptide content on the open internet is this tier, sold as the first one.
Lab ranges: yours wins
The reference interval printed on your own report is the one that counts, because it belongs to the assay and the instrument that produced your number. Where this site shows a generic range, it is labelled generic. Where it shows an optimal band, that band is non-diagnostic — a convention drawn from clinical literature and community practice for reading a trend over time, not a threshold that diagnoses anything. Whether a value is a problem is a question for a clinician holding your whole chart.
Assay method is treated as part of the result
Sensitive (LC/MS-MS) estradiol and standard immunoassay estradiol are not the same measurement. Neither are direct-immunoassay free testosterone and equilibrium dialysis. Pages here name the method whenever it changes the answer, and the app stores it alongside the value.
No dosing instructions to individuals
Pages describe what the literature and community practice report, and show the basis for every number. They do not tell a reader with a particular result to take a particular drug at a particular dose. That is a prescribing decision, and it needs someone who can examine you.
No sponsored reference content
No reference page on this site is sponsored, and nobody can buy a mention on one. The calculators and the marker pages carry no vendor, no compound source, no clinic, no laboratory and no affiliate link to any product. TherapyLog sells no compound and takes no referral fee or commission from any clinic, pharmacy or laboratory for sending anyone to them.
What it does earn from, stated plainly: subscriptions to the app, and flat monthly listing fees in the provider directory, which is a separate, clearly labelled part of the site. Those fees are published, identical for every partner in a tier, and do not vary with how many people a partner refers. A directory listing buys placement in the directory and nothing else — not a mention, a recommendation or a link on any reference page. TherapyLog also runs an affiliate program that pays a commission on software subscriptions; affiliate links point at the app, never at a product, and never appear in reference content.
Corrections
If something here is wrong, write to hello@therapylog.app and say what and why — a citation helps most. Substantive corrections are made on the page and noted on it, with the date, rather than quietly edited away. The review date changes when the page does.
What the tools do, and what they do not
- The calculators do the arithmetic you typed, and nothing else. They cannot know what is actually in your vial. Confirm the strength and the diluent volume on your own label before you draw anything.
- The app flags a value against your lab's printed range first, and a generic range only when your report did not carry one.
- Serum-level curves are estimates from published half-lives, modelled, not measured. Where a half-life is an estimate from limited human data, the page says so.
- Nothing on this site diagnoses, treats, prescribes or monitors anyone. It is a record-keeping and reference tool for adults, and it is not a substitute for professional medical advice.
- Your health log is stored on your device, not on a server. The only times any of it leaves the device are when you send a question to the AI assistant in Personalized mode and when you upload a lab report to the scanner — the app asks before the first time either happens, and both can be turned off. Other parts of the site do talk to servers for ordinary reasons: payment goes through Stripe, a license check calls the API, and an email signup goes to the mailing list. All of it is set out in the Privacy Policy and the Consumer Health Data Policy.
