CoreAge Rx
What we like
- 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
The caveats
- Not the cheapest — flat-price challengers like Trimi Health and Alan Meds undercut its sticker price
- No FDA-approved brand-name option (compounded only)
- Does not yet publicly name its 503A/B pharmacy partner
Onyx Weight Loss
What we like
- 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 caveats
- 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
