Choosing between TelosRX and Diadara for GLP-1 weight loss comes down to price structure and where you are in your journey. TelosRX publishes lower entry pricing and holds one rate as your dose is titrated. Diadara is built around provider-supervised maintenance and the lowest effective dose. Both are LegitScript-certified, both publish their prices, and both require approval by a licensed provider.
If you want the lowest published starting price and a monthly cost that stays flat as your dose changes, TelosRX is the simpler choice. Diadara fits if your priority is a program explicitly designed around long-term maintenance and stepping down to the lowest effective dose.

What is TelosRX?
TelosRX is an online-first, LegitScript-certified telehealth service focused on GLP-1 weight management. It offers compounded semaglutide and compounded tirzepatide, prescribed only when a US-licensed clinician approves them.
The model is asynchronous. You complete a short intake online, a licensed clinician reviews it, and there is no appointment to book. If you are approved, medication is prepared by a licensed US partner compounding pharmacy and shipped to your door with free 2-day delivery included in the plan price.
Pricing is published on every product page before you start, and it is flat: your monthly cost does not change as your clinician titrates your dose upward. Plans include unlimited messaging with your care team, dose adjustments, and quarterly labs. You can cancel in one click with no cancellation fee.

What is Diadara?
Diadara describes itself as a modern apothecary and positions its weight program around provider-supervised maintenance. Its own headline framing is aimed at people coming off weight-loss medication who want to hold their results at the lowest effective dose, decided by a licensed provider.
Diadara is a technology and administrative-services company. It states plainly that it does not practice medicine. Clinical care is delivered by an independent, physician-owned professional corporation, and its licensed providers make every diagnosis and prescribing decision. Diadara displays a LegitScript seal with a live verification link.
The catalog is broader than weight loss. Diadara also lists sexual health, skin, longevity, energy, and recovery categories. Its weight program uses compounded semaglutide and compounded tirzepatide, each offered as an injection or as a tablet.
Two features stand out as genuine strengths. The first is a plain-language education assistant called Sage, which Diadara is careful to say educates only and never diagnoses, prescribes, or collects medical history. The second is the maintenance and tapering framing. Diadara's published process says your provider checks in at least every six months and your plan adjusts with you, including tapering off entirely if that is the right call. Few GLP-1 platforms put the off-ramp in writing.
Medications: what each program offers
Both services center on the same two molecules. Semaglutide is a GLP-1 receptor agonist. Tirzepatide is a dual GLP-1 and GIP receptor agonist, which means it acts on two gut-hormone pathways involved in appetite signaling rather than one.
Both companies offer these as compounded preparations, and both label them clearly as not FDA-approved and not equivalent to brand-name products. Neither lists brand-name GLP-1 medication in its weight catalog. Both offer a needle-free route: Diadara sells semaglutide and tirzepatide tablets, and TelosRX offers a daily oral GLP-1 taken under the tongue. That row is a genuine tie.
Where the catalogs differ is at the gentle end. TelosRX also lists microdosed tirzepatide as a separately priced plan for people who want to ease in at a lower dose. Diadara practices dose minimization clinically through its lowest-effective-dose philosophy, but does not publish a distinct microdose product. For background on this drug class, see the NIH NIDDK overview of weight-management medications and the FDA overview of drug compounding.
Key takeaway: Both companies publish their prices honestly, which is rarer than it should be. The real difference is what happens to that price later. TelosRX holds one flat rate through titration. Diadara's own shipping and refund policy states that when a provider adjusts your dose, your price may step up or down with it.
Pricing and transparency
Neither company hides its numbers, so this is a straight comparison rather than a transparency argument.
TelosRX publishes the following monthly rates as of publication:
- Semaglutide, as low as $99 per month
- Microdosed tirzepatide, as low as $116 per month
- Injectable tirzepatide, as low as $139 per month
- Oral GLP-1, as low as $269 per month
Diadara publishes these starting rates on its weight page:
- Compounded semaglutide injections, from $270 per month
- Compounded semaglutide tablets, from $310 per month
- Compounded tirzepatide injections, from $350 per month
- Compounded tirzepatide tablets, from $390 per month
Diadara's pricing is genuinely all-in, with no separate membership fee layered on top, and the full price is shown before you commit. That is a fair and well-executed model. The word to read carefully is "from". Diadara's published shipping and refund policy explains that your price may step up or down as your provider adjusts your dose. The same policy caps prepaid supply at six months.
TelosRX plans are also all-in, with free 2-day shipping and free consultations included, and they are FSA and HSA eligible. The flat-rate structure means the figure you see at signup is the figure you keep paying as your dose is titrated. Start your intake to see your plan price in a few minutes.
How the process works
Both platforms start with a short online assessment, and neither prescribes automatically.
TelosRX is built for a fast, appointment-free start. The intake takes about five minutes, a US-licensed clinician reviews it asynchronously, and approved medication ships with free 48-hour delivery. There is no video visit to schedule.
Diadara runs a five-step journey. A roughly two-minute intake, review by a licensed US provider, plan selection if a program fits, provider check-ins at least every six months, then automatic refills you can switch to manual or cancel at any time. Diadara is unusually clear about where asynchronous care is available. Its site states that questionnaire-based care is offered in 44 states, and that a live consultation with a provider is required before treatment in seven jurisdictions. That disclosure is more specific than most competitors publish, and it is worth checking before you assume you can start online.
On the pharmacy side, Diadara says every prescription is filled by a licensed US partner compounding pharmacy, and its pharmacies page explains the credentials it looks for. At the time of writing, that page says partners will be listed once their credentials are verified. Individual pharmacy names are not publicly listed yet.
Support and ongoing care
This is where the two models diverge most, and neither answer is wrong.
Diadara's support is structured and periodic. Providers check in at least every six months, refills run automatically by default, Sage is available for plain-language education, and the site advertises 24/7 support. The design intent is a plan that quietly evolves with you over years rather than one that pushes for a bigger dose.
TelosRX support is continuous and clinical. Plans include unlimited messaging with your care team, dose adjustments as your body changes, and quarterly labs, which Diadara does not publish as part of its weight program. If you want frequent contact and lab data behind your dosing decisions, that is a meaningful difference. You can check your eligibility in about five minutes.
One is not strictly better than the other. If you are already stable and want light-touch supervision with an explicit path to taper, Diadara's cadence is a good match. If you are earlier in the process, or want fast answers when side effects show up, more frequent contact tends to matter more.
Safety and medical oversight
Both services gate medication behind a licensed provider, and both are LegitScript-certified, which is an independent check that a service operates legally and transparently. Neither prescribes on demand.
Diadara publishes a dedicated safety page carrying the boxed warning for both semaglutide and tirzepatide, covering the risk of thyroid C-cell tumors seen in rodent studies. It also carries the standard contraindication for anyone with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2. That is the same screening any responsible GLP-1 provider applies.
Providers also screen for issues such as pancreatitis and pregnancy. Side effects can include nausea and digestive changes, particularly while the dose is being increased. Compounded medications from either company are not FDA-approved and are prepared by licensed US pharmacies only against a valid prescription.
TelosRX includes quarterly labs and unlimited care-team messaging so concerns can be flagged early. Whichever service you choose, share your full medical history during intake, because approval is subject to medical review and is never guaranteed.
Which service is right for you?
Best for a lower published starting price, a monthly cost that stays flat as your dose is titrated, quarterly labs, unlimited care-team messaging, and a fast appointment-free start from a LegitScript-certified service.
Best for people focused on long-term maintenance, who want a program explicitly built around the lowest effective dose, a written path to tapering off, and clear plain-language education alongside a broader wellness catalog.
For most people comparing cost first, TelosRX is the more affordable place to start and the more predictable place to stay. The price you see at signup is the price you keep. If maintenance is your entire reason for shopping, Diadara has built its brand around exactly that, and it deserves a look.
