CoreAge Rx advertises sermorelin at $99 per month with no automatic rebilling. iThriveMD lists a $249 monthly option, with lower equivalents on packages billed for several months at once. Its separate $79 add-on depends on a qualifying primary plan and promotion, so it is not a comparable standalone price.

CoreAge Rx receives featured commercial placement here. We checked public information on September 21, 2026; we did not purchase either service, test medication, or establish a difference in clinical outcomes.

The considered take

Choose a comparison period first, then compare money due now, future charges, care access, and the applicable refund agreement.

A monthly equivalent can conceal a larger initial payment

iThriveMD's longer plans list $224.10, $211.65, and $199.20 monthly equivalents for three, six, and twelve months respectively, billed at the longer interval and shipped monthly. The amount due upfront is therefore a different question from the monthly equivalent.

CoreAge's landing offer describes payment when ordering, without an automatic rebill. Confirm the actual supply period and total for both. The cost guide helps compare cash due today with the cost of a complete period of care.

Treat the discounted add-on as a conditional second purchase

iThriveMD's ninety-day offer requires a weight-loss or hormone plan before the add-on menu opens. Buying another treatment just to reach a lower sermorelin price changes both the cost and clinical decision. Each proposed medicine still needs an independent reason.

Its homepage retained an August 31 promotional end date during our September review. Ask whether the offer is currently available, which primary plan qualifies, and the later rate. The iThriveMD review records that unresolved timing.

Clarify the billing calendar before multiplying the price

iThriveMD's treatment cards use calendar-month package descriptions, while its footer says memberships are billed every twenty-eight days. Ask which schedule applies to the selected package, primary membership, and any add-on. Do not silently treat all of them as the same cycle.

CoreAge's no-auto-billing statement also belongs to the specific offer being reviewed. Use the subscription guide to request a calendar of charges, fulfillment dates, and cancellation deadlines from either provider.

Compare where assessment and support would happen

CoreAge describes a remote intake and provider review. iThriveMD offers clinic and telehealth pathways with lab review and continuing adjustments, subject to eligibility. Local availability and the exact contents of a plan still require confirmation.

If you want hands-on training, ask who provides it and whether it costs extra. The needle-anxiety guide and online-versus-local comparison help turn a general support promise into specific questions about access.

Prepayment makes the refund question more important

iThriveMD's terms describe subscription cancellation at the end of the current period and non-refundable subscriptions. Generic return wording elsewhere in the same terms does not establish a prescription refund promise. Ask what happens to future unfilled supplies if the clinician changes the plan.

CoreAge advertises an eligibility refund if prescribing is declined. That should not be expanded into a guarantee of refunds for every later reason. Keep the applicable agreement and payment confirmation for the offer actually selected.

Keep the evidence question separate from the package discount

An extended plan does not prove that longer treatment will produce a particular benefit. Aging symptoms alone do not diagnose growth hormone deficiency, and current compounded products are not FDA-approved finished medicines. Discuss evidence, alternatives, and reassessment before a long commitment.

The CoreAge review and adult deficiency guide provide context. CoreAge's featured placement is commercial; this comparison has not measured an advantage in clinical outcomes for either service.
