Written for anyone on testosterone therapy. Loopa asks what you are on, never why. Resistance-forward training with recovery counted as part of it, protein moved up, a week planned around your own strongest and roughest days, a lean-mass protection score, several compounds each on their own schedule with reminders and supply, an estimated level chart drawn from your own doses, a lab log with no reference ranges, and a summary for your prescriber. It gives no medication advice.
Premium · Everything you record stays yours
Switch testosterone therapy on and the training side leans toward resistance work, protein moves up inside a sourced range, and recovery is given more room: a hard week followed by poor sleep is something Loopa shows you rather than something it ignores. The record runs alongside (doses, symptoms, a daily check-in and your labs) and it never suggests a dose, a timing or a lab window. Once your logs have a shape, the week is planned around it.
Bhasin and colleagues note in the Endocrine Society guideline in Journal of Clinical Endocrinology & Metabolism (2018) that in placebo-controlled trials in healthy and mobility-limited older men, testosterone therapy resulted in greater gains in lean body mass, maximal voluntary strength and muscle power than placebo. Loopa’s training side rests on progressive overload, which the ACSM position stand in Medicine & Science in Sports & Exercise (2009) defines as the gradual increase of stress placed upon the body during exercise training, and a strength card on the protocol screen tracks your best estimated one-rep max, exercise by exercise, over 90 days.
Protein moves up inside a sourced range: Morton and colleagues found in British Journal of Sports Medicine (2018) that gains in fat-free mass from resistance training plateau above total intakes of about 1.62 g/kg a day. And sleep is treated as part of the training rather than separate from it, because Lamon and colleagues found in Physiological Reports (2021) that acute sleep deprivation reduced muscle protein synthesis by 18%. The protein target is yours to set, anywhere from 1.2 to 6 g per kilogram; the default sits inside the sourced range with its source under the number.

After three complete dose cycles with daily check-ins, Loopa places every day by how many days it fell after a dose and averages what you logged there: energy, mood, sleep, symptoms and the sessions you finished. From that it names your own strongest days and your own roughest, in your own numbers (a line of the shape “your logs show days 2 and 3 after a dose are your strongest”) and says “still learning” until it has enough to say anything. It describes what you logged and never explains it. A protocol dosed every day has no cycle to learn, and runs from the check-in instead.
Then the week is built around it. Heavy sessions and protein-dense days land on your strongest days, mobility on your roughest, and the evening before a dose day is a prep day: fluids up, easy protein-forward meals planned, no new PR attempts. Dose days are calendar markers, and Loopa never moves one. A program of your own keeps its days and is only labeled; heavy days cap at two a week, because recovery is weighted up on testosterone therapy. If you run more than one protocol and they disagree about a day, the more protective reading wins. Before the pattern is ready, the week runs from today’s check-in and last night’s sleep. And on a low day (energy at 2 or under, or a symptom at 4 or over) Loopa offers a 10 to 15 minute session instead: full body, upper, lower or mobility, each with a no-equipment version. It keeps your streak and counts in full.
Premium
On testosterone therapy the training is the point, and this is the weekly check on whether the week did its part: each week Loopa scores what is in your own hands, from 0 to 100: the days you reached your protein goal (45% of the score), your resistance sessions against three a week (35%), and the direction of your lean-mass estimate over four weeks (20%), counted once two body-composition points exist. One line says what moved it, and seven weeks of history sit underneath. It is about protecting your own training results, it says nothing about your medication, and every input shows its source in the app.
The protein input counts the days you reached your goal, not how far past it you went: Morton and colleagues found in British Journal of Sports Medicine (2018) that gains in fat-free mass from resistance training plateau above total intakes of about 1.62 g/kg a day. The resistance input rests on the ACSM position stand by Donnelly and colleagues in Medicine & Science in Sports & Exercise (2009): resistance training does not enhance weight loss but may increase fat-free mass and the loss of fat mass. The score starts after two weeks of both food logs and completed sessions, and a short session on a low day counts.
Premium
A testosterone therapy profile takes as many compounds as you take, each named by you, each on its own schedule: daily, every other day, twice weekly, weekly, every two weeks, every N days, set days of the week, on-and-off cycles with an anchor date, or as needed. For an intramuscular injection the body map offers the glutes, the ventrogluteal sites, the deltoids and the quads, and Sites shows a 90-day heat map of where you have actually been going.
Reminders come in three tiers per compound (the day before, an hour before and on the day) and name the protocol and the tier, never the compound, because a lock screen is read by whoever is looking at it. Supply is per compound too: how many units you have, what kind, how many doses in one, and from that a run-out date and a warning when you are close. It counts the doses you logged. Add a refill date and your pharmacy’s lead time and the supply card gives you a reorder-by date, with a reminder on the day; it is on unless you switch it off.
Premium
The estimated level chart draws where a compound sits relative to its own peak over the days you choose, from two things: the doses you logged, and a published elimination half-life for the name you entered, where one exists. It is drawn in percent of peak rather than any clinical unit, it is labeled as an estimate, and it carries no annotations, no bands and no markers of any kind. A name that matches nothing in Loopa’s small, cited table gets no chart, and Loopa says so rather than guessing; gels and patches get no chart either.
The volume calculator takes an amount in mg and a concentration in mg/mL and returns the volume in mL and the syringe units. The reconstitution calculator takes the amount in a vial and the volume of diluent and returns the resulting concentration. Neither carries a default, neither suggests a value, and every result carries the line that says what it is: a conversion of your own numbers, for information.
PremiumLoopa also tracks peptide and multi-compound injection protocols you define yourself, with the same log, reminders, supply and reconstitution math.
Four sliders a day, one to five. On a testosterone therapy profile there is a fifth, libido, and it is off until you switch it on. It is stored like the rest of your record, encrypted with your key, and it is never part of what a coach is shown, even where you record it. The protocol screen shows the 14-day average for each slider and the line it makes. A check-in can carry a question in your own words for your next appointment. And beside the symptom journal, Loopa counts the foods you logged in the three hours before a symptom, by food and by category, and shows a pattern only once it has appeared five times and in at least half of that symptom’s entries. “Heartburn logged within 3 hours of fried foods, 6 of 8 times.” Counts, never a cause.
PremiumType in a lab result (the marker, the value, the unit you used) and watch it over time. On iPhone, if you grant it, results already in Apple Health’s clinical records can be read in for the markers you approve; nothing is ever written back. Loopa keeps what you entered and converts nothing; if a trend mixes two units, the chart says so instead of quietly reconciling them. And there are no reference ranges: no green zone, no red zone, no in range or out of range. A range belongs to the laboratory that ran the test and to the clinician reading it, and it is not Loopa’s to publish. A DEXA scan goes in as four markers (lean mass, fat mass, bone mineral density and T-score) kept exactly as entered and drawn on your body-composition trend, and a lab can carry a question in your own words for your next appointment. An optional reminder nudges you when it has been a while since your last panel; it never says which tests to ask for.
PremiumPick a window of up to 400 days and Loopa lays out what you logged: doses and their sites, the symptom pattern, the wellbeing trend, your labs exactly as you entered them, and your weight, body-composition and strength trends, as a PDF or a spreadsheet. It is a record of what you reported and makes no recommendation about your medication. It is built when you ask and handed straight to you; no copy is kept, and the fact that you made one is written into your own access record.
Your questions come first. A question you attached to a symptom, a check-in or a lab is listed in order on the summary’s first page, in your own words, so the appointment opens with what you wanted to ask. And between appointments, Progress keeps the record the scale does not: strength records, measurements, your energy and sleep trend, streaks and the lean-mass history. When your weight’s seven-day average has held within about one percent for three weeks, Loopa leads with that ledger.
Premium
If you have a Loopa coach, testosterone therapy support is its own switch on your consent screen, and it starts off. Switched on, it shows your coach exactly three things: the symptom pattern as counts, which days of the week your doses fall on, and your 14-day wellbeing averages. It never shows the compound name, any amount, any lab value, a note, your supply figures or your calculator results, and it never shows libido, even where you record it. A multi-compound protocol you define yourself is never shared with a coach; there is no switch for it. Once you confirm the updated sharing list for that coach, it can also place your dose days as markers on the calendar your coach sees and label your strongest and roughest days, two words, with nothing behind them. A switch you set before the list changed keeps exactly what it had until you confirm.
It records what you report and reflects it back. Every medication screen in the app carries the same line: questions about your medication belong with your prescriber.
Nothing in Loopa tells you to start, stop, skip or change anything, when to take it, or which tests to ask for. A reminder fires on the schedule you set. A lab nudge says only that it has been a while. Dose days on the week plan are calendar markers, and never move.
The estimated level chart is drawn from the doses you logged and a published half-life, in percent of its own peak, labeled as an estimate, with no annotations. The two calculators convert what you typed and carry no defaults.
Nothing to browse, nothing that describes what anything does, and nothing that checks a name against a dosing reference. Every name in your protocol is text you typed, encrypted with your own key.
The symptom pattern, the food patterns, the week plan, the lean-mass score, the wellbeing trend and the prescriber summary describe what you recorded and stop there. They do not conclude, they never say why, and they make no recommendation about your medication.
What people ask before they switch the protocol on.
No. Loopa gives no medication advice. It never suggests a dose, a timing or a lab window, the level chart is an estimate drawn from your own doses with no annotations, and the calculators convert numbers you typed. Every medication screen says the same thing: questions about your medication belong with your prescriber.
Medication protocols are part of Loopa Premium, all of it: setting a protocol up and naming what is in it, the dashboard and goal targets, the dose log with the body map, reminders and supply, the calculators and the estimated level chart, symptoms, the wellbeing check-in, labs, the trends, your pattern, your week, the lean-mass protection score, the protein-gap options, the summary for your prescriber and the Off-Ramp. Everything you record stays yours.
No. The testosterone therapy profile is written for anyone on testosterone therapy. Loopa asks what you are on, never why, and nothing in the app assumes your reason for being on it.
From a small table Loopa holds, every row of it taken from an approved product’s own labeling or from a published human study, with the sentence that states it quoted on the row. A name that matches nothing in that table gets no chart, and Loopa says so rather than inventing a number. Gels and patches get no chart either, because the model behind the curve cannot represent that kind of delivery.
No. Testosterone therapy support shows a coach the symptom pattern as counts, which days your doses fall on, your 14-day wellbeing averages and, once you confirm the updated sharing list, your dose days as calendar markers with your strongest and roughest days labeled, and nothing else. Libido is never shared, even where you record it, and neither is a lab value, a compound name, an amount or a note.
No. A reminder names the protocol and the tier (the day before, an hour before, on the day) and never the compound, because a notification on a lock screen is read by whoever is looking at it.
That Loopa does not yet have enough of your own logs to say anything. The pattern needs three complete dose cycles with daily check-ins before it names your strongest and roughest days, and each days-since-dose group needs three check-ins before it scores. Until then the screen says so, and the week runs from today’s check-in and last night’s sleep. A protocol dosed every day has no cycle to learn and stays on that path. Nothing is guessed to fill the gap.
No. Dose days are calendar markers, taken from the schedule you set and the doses you logged, and the week plan is built around them: heavy work on your strongest days, mobility on your roughest, a prep day the evening before a dose. Loopa never moves a marker, suggests one or adds one. The days themselves are yours and your prescriber’s.
Only after you confirm the updated sharing list for that coach. Then testosterone therapy support can place your dose days as markers on the calendar they see and label your strongest and roughest days, two words, with nothing behind them: no check-in value, no symptom, no compound name, no amount and no lab value. A switch you set before the list changed keeps exactly what it had until you confirm.
