Factor by factor
The six factors behind each Value Score. The orange bar marks the stronger side. See the methodology.
CoreAge Rx
The honest lowest price: both molecules at one flat, all-in monthly rate that never steps up after month one.
Why it's a deal
- Flat, all-in monthly price with no intro-rate step-ups after month one
- Both compounded semaglutide and tirzepatide on one account
- Available in all 50 states
- Straightforward, low-friction cancellation — no lock-in
The fine print
- Not the rock-bottom sticker — a couple of teaser tiers advertise lower month-one rates
- No FDA-approved brand-name option (compounded only)
- Does not yet publicly name its 503A/B pharmacy partner
Onyx Weight Loss
Onyx Weight Loss is a nurse-practitioner-led telehealth clinic based in Mooresville, NC, offering GLP-1 and GLP-1/GIP weight-loss medications alongside peptides and HRT across 8 states.
Why it's a deal
- 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
The fine print
- 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
