Oak Longevity vs PlexusDx
Oak Longevity: A small cash-pay telehealth program whose $133/month flat semaglutide price is currently the lowest month-to-month figure in our semaglutide index. PlexusDx: PlexusDx sells flat-rate compounded protocols with no membership: $149/month semaglutide injection (flat from 0.25 to 2.0 mg weekly), $249/month tirzepatide injection (flat from 2.5 to 15 mg), a $129/month microdose protocol, and an optional genetic test the company positions as personalization.
Tirzepatide
Only PlexusDx offers tirzepatide ($249 a month billed monthly); Oak Longevity does not, so there is no contest to score.

The arithmetic
On the figures our desk holds, Oak Longevity's $133 a month undercuts PlexusDx's $149 by $16 a month at the 2.4 mg/wk maintenance basis — $192 across a year. Oak Longevity's figure is provider-stated (captured 2026-08-08) and PlexusDx's is provider-stated (captured 2026-08-11); a status below 'verified' means our independent checkout capture is still pending, so treat the gap as the best current evidence rather than settled fact.
Oak Longevity's semaglutide ladder runs $133 a month billed monthly. PlexusDx's runs $149 a month billed monthly. On the twelve-month basis Oak Longevity's $1,596 beats PlexusDx's $1,788 by $192 — with the winner's figure resting on twelve months at the month-to-month rate with no commitment, a structural difference that matters if you might stop early.
Where the structures genuinely differ
On verifiability, Oak Longevity names its dispensing pharmacy — which means the fifteen-minute license-and-records check is possible — while PlexusDx's pharmacy is not disclosed on record, the single structural fact this desk weighs heaviest after the FDA's 2026 letters cited exactly that practice.

What our desk is watching on each
Oak Longevity: Small operator; pharmacy partner not publicly itemized. Price captured from the provider's published pages; checkout capture pending.
PlexusDx: Provider-stated throughout: every figure here comes from PlexusDx's own published materials, which the company distributes inside competitor 'reviews' on its blog — a marketing format worth noting even when the numbers are consistent. The optional 'Precision Peptide Genetic Test' is an upsell whose clinical utility for dose selection is not established by the class's trial record; the microdose protocol is sub-maintenance by design and is not ranked at the maintenance basis. Pharmacy names undisclosed on captured materials — the verification workflow stalls at step one until answered. Independent checkout capture pending.
Questions people ask
Is Oak Longevity or PlexusDx cheaper in 2026?
The tirzepatide and semaglutide verdict blocks above give the computed answer at the maintenance basis, with the verification status of each figure; the short version is that whichever program's all-in monthly number is lower on this page is cheaper on the evidence we hold today, and both rows carry capture dates so you can judge freshness.
What does Oak Longevity vs PlexusDx miss that checkout will show?
Taxes, state availability, current promotions, and any dose surcharge introduced after our capture date. Screenshot the order summary before paying — that capture, not any comparison page, is your contract.
Why do you compare at the maintenance dose instead of the starting dose?
Because starter pricing lasts one or two months and maintenance pricing lasts the rest of the year; comparing starts against maintenances is the single most common way GLP-1 comparisons mislead.
What do Oak Longevity and PlexusDx cost over a full year of semaglutide?
On the plans our database holds, a year of semaglutide runs $1,596 at Oak Longevity and $1,788 at PlexusDx — computed from each program's best published twelve-month route, with promotional figures labeled in the sections above and every number carrying its capture date.
