Cellular Pathway.
Support aimed at the level beneath symptoms. This is the pathway with the most enthusiasm attached to it and the least settled evidence, and we would rather tell you that plainly than sell around it.
- Physician evaluated before anything is prescribed
- Only compounds that are legally available are offered
- Evidence stated honestly, including where it is thin
- Availability varies by state and is confirmed at evaluation
The most interesting, and the least settled.
Cellular support covers compounds studied in relation to energy metabolism, recovery and repair. The mechanisms are frequently well described. The clinical evidence in healthy adults is generally thinner than the marketing around it suggests, and in several cases considerably thinner.
We offer this because there is genuine science underneath and the safety profiles are reasonable. We are not going to tell you it reverses ageing, and anyone who does is not reading the same literature.
How we handle this pathway
- Only compounds legally available for compounding are offered
- Mechanism explained separately from outcome evidence
- Where evidence is preliminary, we say so
- Facility modalities offered as an alternative where appropriate
Where it can start.
Seven therapies across three tiers. Which apply to you is decided by evaluation rather than selection, and several are frequently prescribed together.
NAD+ Therapy
A coenzyme central to mitochondrial function and cellular energy production, with levels declining naturally with age.
- Mechanism well characterised
- Outcome evidence in healthy adults developing
- Delivery route affects what reaches you
Sermorelin
Stimulates your own pituitary to release growth hormone rather than replacing the hormone directly.
- Works within existing hormonal pathways
- Studied for recovery, sleep and body composition
- Physician evaluated before prescribing
B12-MIC
Nutrient support where deficiency is documented, combining B-12 with methionine, inositol and choline.
- Useful where deficiency exists
- Testing preferred over assumption
- Honest about what it does not do
L-Carnitine
Involved in transporting fatty acids into mitochondria for energy production.
- A defined metabolic role
- Evidence in healthy adults is modest
- Frequently paired within a programme
Lipo-C
A lipotropic formulation used alongside metabolic programmes rather than on its own.
- Used as programme support
- Not a standalone weight intervention
- Prescribed where clinically appropriate
Glutathione
Studied in relation to oxidative stress and the body's own detoxification pathways.
- A different mechanism from NAD+
- Studied for oxidative stress
- Delivery route matters considerably
Methylene Blue
At low doses, studied for its effect on the mitochondrial electron transport chain.
- Dose dependent, and low dose specifically
- Studied for cognitive and energy endpoints
- Interactions require careful review
Mechanism first, then the evidence.
Separating those two is the whole discipline of this pathway, and where most providers in this category collapse them together.
Complete the intake
History, medications, symptoms and what you are hoping to change.
Testing where indicated
Deficiency confirmed rather than assumed, where the compound depends on it.
Physician review
Appropriateness assessed, with the evidence base explained honestly for what you are considering.
Treatment and review
Where prescribed, with a defined point to assess whether it is doing anything for you.
And who it is not for.
Evaluated honestly, and frequently declined.
People interested in energy and recovery at the cellular level
Anyone who wants the evidence stated rather than the marketing repeated
Members already addressing the fundamentals who want to layer on
People prepared to test for deficiency rather than assume it
Not appropriate with certain cancer histories or endocrine conditions
Not appropriate as a substitute for sleep, training or nutrition
What we will and will not claim.
This category attracts more overpromising than anything else in telehealth, and being clear costs us sales we would rather not make.
Mechanism is not outcome
That a compound participates in an important biological process does not establish that supplementing it changes anything you would notice. This distinction is where most of the marketing in this category quietly fails, and we will keep them separate.
Peptide regulation is unsettled
In July 2026 an FDA advisory committee recommended adding several peptides to the compounding list. That recommendation is nonbinding and changed no law. We offer only what is legally available, and update this as the position changes.
Facility modalities may serve you better
For local members, several of the effects people seek here are addressed through modalities with clearer evidence. Where that is true we will say so rather than take the prescription revenue.
Longevity Gyms does not prescribe
Longevity Gyms is a non clinical performance and recovery facility. We do not prescribe medication and we do not provide medical care. Care within Vitality is delivered by licensed physicians through our telehealth infrastructure partner, and your clinical relationship is with that practice. Your evaluation, prescription, records and follow up all sit with them. Availability varies by state, and not every programme is offered everywhere. We state this plainly because you should know who is responsible for your care before you begin.
Questions answered.
Does NAD+ actually work?
The mechanism is well characterised and levels do decline with age. Clinical outcome evidence in healthy adults is developing rather than settled. We will explain what is established and what is not, and let you decide.
What about peptides?
We offer only peptides legally available for compounding. The July 2026 advisory committee recommendation was nonbinding and did not change the law, despite considerable marketing suggesting otherwise.
Is this anti-ageing?
We will not use that framing. These compounds are studied in relation to specific biological processes. Extrapolating from that to reversing ageing is a leap the evidence does not support.
Do I need testing first?
For nutrient support, yes where deficiency is the rationale. Supplementing something you are not short of is a common and avoidable waste.
How is sermorelin different from HGH?
Sermorelin stimulates your own pituitary to release growth hormone rather than replacing the hormone directly. That is a meaningfully different mechanism with a different profile.
Will I feel a difference?
Some people report one, some do not, and expectation plays a real role in this category. We would rather set that expectation honestly than have you judge it against a promise we never should have made.
Is this better than what you offer in Hanover?
Frequently not. For local members, several facility modalities address these goals with clearer evidence, and we will tell you where that applies.
Is this available where I live?
Availability varies by state and is confirmed during your evaluation before you commit to anything.
Who prescribes?
A licensed physician through our telehealth infrastructure. Longevity Gyms does not prescribe medication.
Frequently assessed together.
These areas overlap more than most people expect, and are often addressed as one picture.
Metabolic Pathway
Energy, weight and glucose handling are closely connected to cellular metabolism.
Hormone Pathway
Frequently assessed together, since fatigue and recovery symptoms overlap considerably.
Sleep Pathway
Recovery happens during sleep, and no compound compensates for sleeping badly.
See If You Qualify.
One evaluation covers this pathway. In it you will:
- Share your history, medications, and what you want to change
- Have your case reviewed by a licensed physician
- Find out which options are appropriate for you
- See pricing and availability before committing
- Receive an honest answer, including no where that applies
