Best Lab Testing Services for TRT, Longevity & Performance

What you get. A membership rather than a one-off test: 160+ lab tests annually, with testing twice a year plus on-demand additions. The panel is genuinely broad — hormones including testosterone, free testosterone and estradiol; the cardiovascular set that actually predicts events (ApoB, Lp(a), hs-CRP, homocysteine); metabolic markers including fasting insulin; thyroid; nutrients; heavy metals and toxins. Clinicians review every result and flag anything abnormal, and you can add MRI or CT scans at extra cost.

Pricing. $365 per year as of verification, reduced from an original $499. HSA and FSA eligible. Draws happen at partner patient service centers, not at home.

Honest assessment. For someone tracking longevity biomarkers over years, this is the best value on the list on a per-marker basis — buying the same 160 markers à la carte would cost several times more. The limitations are real, though. Function does not prescribe, so if your testosterone comes back at 280 ng/dL you still need a clinician elsewhere. The 'insights' are pattern-matched summaries, not a treatment plan. And twice-yearly testing is too infrequent for anyone titrating a hormone protocol — you will need interim draws regardless.

What you get. Marek is built around hormone optimization specifically, not general wellness. Comprehensive and Complete panels cover the full androgen picture — total and free testosterone, SHBG, LH, FSH, sensitive estradiol, DHT, prolactin, IGF-1 — alongside metabolic and cardiovascular markers. Every panel comes with a lengthy written report and a video review with a coach, and there is a direct path to a prescribing clinician for hormone therapy, peptides, or metabolic treatment.

Pricing. Their coaching partnership materials list the Comprehensive and Complete panels at $455 and $855 respectively at partner cost. Consumer-facing pricing and membership fees vary by protocol — see their website for current figures.

Honest assessment. This is the most clinically serious option for TRT on the list. The panels ask the right questions, the coaches understand the difference between a lab reference range and an optimal range, and they will push back on protocols that look reckless. The cost is the obvious limitation: you are paying concierge prices, and someone whose only question is 'is my testosterone low' is overbuying by a wide margin. There is also an inherent tension in any model where the same organisation interprets your labs and sells you the treatment — worth keeping in mind when a supplement stack is recommended.

What you get. Packaged protocols — testosterone, GLP-1 weight loss, growth hormone peptides, mood — delivered as a monthly subscription with telehealth prescribing. Lab testing is available as an at-home 10-marker testosterone test or a comprehensive panel of up to 146 markers. Their testosterone offering notably includes enclomiphene-based protocols, which preserve fertility and natural production in a way exogenous testosterone does not.

Pricing. Subscription-based with promotional first-month discounts on annual plans. Medication and lab costs are separate line items depending on protocol — see website for current pricing.

Honest assessment. Maximus is the most consumer-friendly on-ramp here, and the enclomiphene pathway is a legitimately good option for younger men who want to avoid shutting down their own production. But the model is optimised for conversion and retention rather than for diagnostic depth. The 10-marker test is a screening tool, not a workup; ongoing monitoring is thinner than what Marek or a good local endocrinologist would insist on; and the subscription framing makes it easy to stay on a protocol longer than the data justifies. Fine as a starting point, weaker as a long-term monitoring relationship.

What you get. The two national reference labs sell directly to consumers. You buy a panel online, a network physician issues the order, you walk into a patient service center, and results land in a portal in a few days. Relevant offerings include total and free testosterone, comprehensive metabolic panels, lipid panels with ApoB, hs-CRP, HbA1c, fasting insulin, thyroid panels, and men's health bundles.

Pricing. Quest lists a total testosterone test at $69 plus a $6 physician service fee. Labcorp OnDemand prices comparable tests in the same range. Bundles cost less per marker than buying individually. Both are HSA/FSA eligible and both run frequent promotional discounts.

Honest assessment. This is where most people should start, and we say that knowing there is no affiliate program here — we earn nothing if you use them. You are buying exactly the markers you decided you need, from the same labs that the expensive services send your blood to anyway. What you do not get is interpretation, a clinician who knows your history, or a prescription. If you can read your own results against an optimal-range reference and you know which markers you want, the value gap versus a $365 membership is enormous. If you cannot, you will stare at a PDF and do nothing with it.

What you get. A test-to-prescription pipeline for men. The initial panel covers eight markers — total testosterone, free testosterone, SHBG, albumin, LH, estradiol, AST and ALT — collected either at a lab or via an at-home kit. If results and symptoms support it, you have a video consult with a licensed physician who can prescribe. Follow-up panels on therapy add prolactin, PSA and hematocrit, which are the right monitoring markers.

Pricing. $45 for the at-lab test or $80 for the at-home kit. The Hone Plus membership for men on TRT runs $135 per month plus medication cost, with a confirmatory test required before starting. Basic and Premium tiers exist for non-TRT longevity care and broader metabolic support respectively.

Honest assessment. The pricing is transparent in a way most of this category is not, and $45 for a real eight-marker hormone panel is hard to argue with. The follow-up schedule includes hematocrit and PSA, which tells you they are monitoring the things that actually cause problems. The limitations: the initial panel does not include a lipid panel, HbA1c, or a complete blood count, so it is a hormone workup rather than a health workup, and the at-home kit's accuracy is inherently weaker than a venous draw. Treat the $80 kit as a screen and confirm anything decision-relevant at a lab.

What you get. Blood biomarkers paired with an algorithm that converts results into food, supplement and training recommendations. Tiers run from a five-marker biological age estimate up to a 40+ marker panel. A one-time DNA kit adds genetic risk context that the platform folds into its recommendations.

Pricing. Roughly $49–$99 for the entry InnerAge tier, $249–$299 for the mid-tier Essentials panel, and $589–$699 for the Ultimate panel per draw, with 15–25% subscription discounts. The DNA add-on is a one-time $249–$299. Prices move with promotional cycles.

Honest assessment. The per-marker cost is the problem: $5–$15 per marker against $2–$8 buying the same tests direct from Quest or Labcorp. You are paying for the recommendation layer, and the recommendations are generic — eat more leafy greens, consider vitamin D, sleep more. The DNA add-on adds very little actionable signal for most people; polygenic nutrition guidance is not at a stage where it should change what you eat. Genuinely useful for an endurance athlete tracking ferritin, vitamin D, cortisol and inflammation across a season. Poor value for anyone who can read a lab report.

What you get. Stool-based gut microbiome sequencing plus blood and saliva options, returning 70+ proprietary 'health scores' including a biological age estimate and inflammation score, with personalised food and supplement recommendations delivered through an app.

Pricing. Kits start around $399. Viome also sells subscription supplements formulated from your results, which is where the ongoing revenue sits.

Honest assessment. This is the weakest fit for our audience. Microbiome sequencing is a legitimate research field, but the translation from a species abundance readout to 'eat these 40 foods' is far ahead of the evidence, and the scores are proprietary rather than validated clinical markers. Nothing it returns will help you titrate TRT, assess GLP-1 candidacy, or track cardiovascular risk. If you have persistent unexplained GI symptoms and have already ruled out the obvious with a gastroenterologist, it is an interesting $399. Otherwise the same money buys a genuinely useful longevity panel elsewhere.
