calc_reconstitute | Work out the units to draw for a prescribed dose from a powder vial and bacteriostatic water. Inputs: vial mg, water mL, the dose (mg or mcg), and the syringe. Returns units, mL, the nearest syringe line and doses per vial. Arithmetic only — the user's own dose, no presets. |
calc_convert | Convert between a dose (mg or mcg), syringe units and mL at a known strength. Give the strength as conc_mg_ml, or as vial_mg + water_ml. Set direction to dose_to_units or units_to_dose. Returns the counterpart plus concentration and mcg per unit. Arithmetic only. |
storage_check | Say whether a GLP-1 pen or a reconstituted peptide vial is still good, given the situation (unopened, in use in the fridge, or left out) and, if left out, how long and how warm. Returns a graded verdict with the SmPC in-use limit. No dosing. |
supply_runout | Work out when an HRT or testosterone gel, spray or sachet pack runs out and when to reorder. Inputs: product (oestrogel, sandrena, lenzetto, testogel_pump, testogel_sachet, tostran), doses per day, optional containers, pack-opened date and reorder lead days. Returns doses left, days, run-out and ord |
patch_calendar | Lay out the change days for an HRT estradiol patch from the day the first patch goes on, and rotate the application site. Products: estradot, evorel, evorel_conti, estraderm_mx (twice weekly); femseven, femseven_conti, progynova_ts (weekly). Optional weeks to show (default 8). SmPC change interval, |
howlong_timeline | Give the SmPC milestones for when a GLP-1/GIP injection starts working: when appetite drops, when the first full dose is, and how the effect builds. Returns dated-by-week milestones with their citation. Informational, no prediction for any one person. |
howlong_clearance | Estimate when a GLP-1/GIP injection is essentially cleared after the last dose, from the SmPC half-life (about five half-lives). Give the drug and the last-dose date. Returns the clear date and whether the basis is the SmPC or an estimate. Informational. |
pen_howto | Give the step-by-step injection walkthrough for a GLP-1 pen (Mounjaro KwikPen, Wegovy, Ozempic or Saxenda), from the maker's UK instructions. Returns the ordered steps and the symptom list you can troubleshoot. Routes to the leaflet; not a substitute for it. |
pen_troubleshoot | Answer a GLP-1 pen problem (won't dial, no clicks, stuck, not at zero, no drop at the needle, a bubble, a leak, cold, unsure) for a given pen, from the maker's UK leaflet. Returns what it means and what to do, with when to stop and call the pharmacist. |
sideeffects_list | List the SmPC side effects of a GLP-1/GIP injection (Mounjaro, Wegovy, Ozempic, Saxenda) by frequency band, plus the serious warnings with what to do (999/111/prescriber) and the Yellow Card link. General leaflet information, not a prediction and not triage. |
compare_medicines | Put two weight-loss/diabetes injections (Mounjaro, Wegovy, Ozempic, Saxenda) side by side on SmPC facts: doses, frequency, pen, licensing, NHS access, storage. Returns a row-by-row table with the rows that differ flagged. Facts only, never a 'which is right for you'. |
protein_target | Work out a daily protein target for someone losing weight on a GLP-1, from weight (and height, which sharpens it) and activity level. Returns grams per day with the band and which body-weight basis was used. General information, not personalised dietetic advice. |
bmi_check | Body mass index from weight and height, with the NHS adult category and the healthy-weight range for that height. UK thresholds; note the NHS lowers them for some ethnic backgrounds. General information, not a diagnosis. |
weight_ideal | Healthy-weight range for a given height, from the healthy BMI band (18.5-24.9), with the BMI-22 midpoint as a single figure. There is no one 'ideal weight'; this is the healthy range. General information. |
waist_ratio | Waist-to-height ratio from waist and height, against the NICE bands (keep your waist under half your height). Flags central-fat risk that BMI can miss. For adults with BMI under 35. General information, not a diagnosis. |
fluid_target | Rough daily fluid estimate from body weight (about 30-35 ml/kg), framed against the NHS 6-to-8-glasses guidance. Needs rise in heat, with exercise, and with GLP-1 sickness. A general estimate, not a medical fluid target. |
energy_tdee | Daily energy use (BMR via Mifflin-St Jeor, then TDEE for activity) and two safe calorie-deficit targets for weight loss, clamped to the NHS lower limits. Needs age and sex for the equation. General information, not a diet plan. |
providers_search | Find UK providers that offer a treatment and are on the CQC/GPhC register. Filter by treatment (glp1-weight-loss, hormone-therapy, iv-therapy, vitamin-injections), kind (online/clinic/mobile), nation, town slug, a name search, or near a postcode. Sort by distance, CQC rating, Google rating or review |
providers_get | Get one registered provider by its slug: its registration wording and rating, the treatments it offers, its locations, and its own published consultation fee where known. Returns null if the slug is not a listable provider. Registration facts only, no recommendation. |
providers_check | Check a provider by name, website URL or postcode against our CQC/GPhC register data. Returns whether it is a registered, listable provider and its registration wording, with how it was resolved. If we don't hold it, returns the official register to search by hand. Never a guess. |
compounds_list | List the UK peptide/compound profiles with their UK legal status (licensed, in trials, cosmetic, or research/unlicensed). Filter by status or category. Returns name, aka, class, status and the licensed alternative. A legal-status index, not a dosing tool. |
compounds_get | Get one compound's UK legal status: whether it is licensed, in trials, cosmetic or unlicensed, the evidence and risks, and the licensed alternative. Returns sources and dates. No dosing is included, by design. |
guides_list | Browse On the Register's plain-English UK guides to weight-loss medicines and the providers who supply them: checking a provider, cost and NHS access, using a pen, and side effects and treatment. Filter by category. Returns each guide's title, summary and page URL to link as further reading. |
