Onyx Weight Loss vs PrescribedRX
The verdict
PrescribedRX takes it — 59/100 to 58.8/100, but only just.
PrescribedRX grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. PrescribedRX is a multi-condition telehealth brand (TRT, longevity, hair loss, sexual health and weight loss) that prescribes compounded GLP-1 injectables for weight loss: semaglutide at $189/month and… Onyx Weight Loss is close behind and may still be the better fit — see the factor split below.

Graded #359 · C
Strengths
- Competitive entry pricing: semaglutide from $228/mo and tirzepatide from $280/mo with medication + supplies included
- Nurse-practitioner-led care: founder Tasha Vangile FNP-C (20+ years) and Stephanie Robison APRN-CNP (27 years experience)
- Low-cost $99/mo GLP-1 microdosing option for patients who prefer a gradual titration start
- Strive Pharmacy partnership implies compounded 503A-quality supply chain from a known pharmacy
- Multi-modal clinic: GLP-1 + peptides + HRT + nutrition coaching available under one provider team
Where it loses points
- Only 8 states (NC, CO, ME, VT, VA, IA, NH, PA) — excludes the majority of the US
- No LegitScript certification; credentialing evidence limited to local 2025 Best of Iredell award
- Specific drug names (semaglutide/tirzepatide) never stated on website; compounded status inferred, not disclosed
- Labs not included or mentioned; no baseline bloodwork protocol published
- Pricing shown as 'Starting at' with no dose-escalation tier pricing disclosed publicly
Graded #351 · C
Strengths
- Compounded semaglutide ($189/mo) and tirzepatide ($276/mo) injectables, with lower per-month pricing on the 3-month plans ($176 and $233/mo)
- Clear, upfront plan pages showing monthly and multi-month pricing with no surprise fees
- Care from licensed US providers with monthly home delivery and ongoing dose support
- Bilingual English/Spanish site and a broader telehealth menu (TRT, longevity, hair, sexual health) for people who want more than weight loss
Where it loses points
- Doesn't publish the states it serves — you only learn eligibility after starting the intake
- Compounding pharmacies aren't named on the site
- Mid-range pricing — cheaper compounded GLP-1 options exist and the 3-month discount is modest
- Compounded semaglutide and tirzepatide injectables only — no brand-name or oral options
- Self-hosted affiliate program (not a vetted network); Florida/Palm Beach framing suggests a regional lean
