About 1st Optimal
Neither a monthly price nor a list of states is published. 1st Optimal operates out of Michigan across telehealth and functional medicine, writing the GLP-1s semaglutide and tirzepatide either as a weekly injection or as a daily oral tablet. Around the prescription it stacks at-home lab testing, interpretation of the blood work, coaching without limit and protocols built individually, all framed as long-term weight loss and longevity. Credentialed providers work virtually, treatment goes to the home, and nothing binds you to a long contract.

CaliberRx shows pricing only after the intake quiz, does not name its pharmacy, and displays no LegitScript. The 100% online platform sells compounded semaglutide and tirzepatide prescribed by licensed clinicians after an online medical-history review, on a no-insurance model with free discreet delivery and 24/7 medical support. It publishes an unusually thorough legal and compliance suite covering privacy practices, telehealth consent, a state-privacy addendum, refunds, billing and disclaimers. Compounded GLP-1s are not FDA-approved.

1st Optimal
What we like
- The monthly figure covers consult, shipping, coaching
- No FDA warning letter matched this operator when we searched our enforcement register
- A live video visit with a clinician is required before a prescription, which is slower than a form and is the more careful intake
- Baseline bloodwork is required before a prescription
Watch-outs
- No price appears until the medical intake is complete, so the cost cannot be compared before health information is submitted
- No state list is on record here, so whether it serves your state cannot be confirmed from this page
- No dispensing pharmacy is named in our record, so its accreditation cannot be looked up from here
CaliberRx
What we like
- Publishes a price on its own site before the medical questionnaire, so it can be compared without handing over health information
- The monthly figure covers medication, consult, shipping
- No FDA warning letter matched this operator when we searched our enforcement register
Watch-outs
- No state list is on record here, so whether it serves your state cannot be confirmed from this page
- No dispensing pharmacy is named in our record, so its accreditation cannot be looked up from here
Our Verdict
CaliberRx takes it, 5.2 against 3.9, and it is especially strong on seeing what it charges before you answer any medical questions. 1st Optimal is no weak second and may fit you better on coaching bundled into the price rather than sold separately.
