Active ingredients
Oxytocin
A metered nasal spray, used as needed rather than daily. Refrigerate and follow the pharmacy label. Effects are typically felt within the hour and are short-lived.
There is no FDA-approved intranasal oxytocin product in the United States, so what follows comes from published human research using this route. The effects most commonly reported are local and short-lived: nasal irritation, a runny nose, and a dry mouth or throat. Headache and lightheadedness or a spinning sensation are also reported, typically starting within the first two hours and settling within a day. Reviews of this literature describe no consistent cardiovascular effects at research doses, though intravenous oxytocin can change heart rate. The serious concern described in the literature is water intoxication and low blood sodium, reported in case reports with excessive doses taken alongside large volumes of fluid — headache, confusion, nausea and drowsiness in that setting require urgent medical attention.
Oxytocin nasal spray is not prescribed to anyone with a known allergy to oxytocin or to any component of the preparation, including its preservative. Published safety reviews recommend excluding people with significant heart disease or another cardiovascular disorder, and people with a seizure disorder or other neurological condition. It is not used in pregnancy — oxytocin acts on the uterus — or while breastfeeding, and it is not used in anyone with a condition or medication that predisposes to low blood sodium. It is avoided where the nasal lining is not intact, and it is used as needed rather than daily, because the reported cases of water intoxication involved excessive or prolonged dosing.
Oxytocin is a neuropeptide produced in the hypothalamus that acts on oxytocin receptors throughout the brain, particularly in regions involved in social cognition, trust, and emotional bonding. Intranasal delivery allows oxytocin to reach the central nervous system more directly, where it is thought to modulate activity in the amygdala and other regions involved in stress and social processing, supporting feelings of connection and reducing social anxiety.

Frequently Asked Questions
Answers on setup, scale, and support to remove blockers.
Your membership includes four targeted lab panels each year, continuous monitoring from the wearable device of your choice, and continuous monitoring of your smart scale to track weight and body composition. You’ll also receive access to our proprietary health scoring system, built on the American Heart Association’s Life’s Essential 8, which gives you a clear picture of your cardiovascular and metabolic health. Membership comes with ongoing support from a dedicated health coach, custom supplements, and access to prescription treatment through independent licensed providers, all managed directly through your dashboard. Additional devices and monitoring tools can be purchased at discounted member pricing.
OneTwenty is a health optimization membership, not a medical practice. We don't diagnose, treat, or cure medical conditions, and we don't practice medicine.
What we do is give you a clearer picture of your own health. Your membership includes quarterly lab testing, integration of your wearable data, and an AI-powered view of your biomarkers and trends over time. The focus is optimization and prevention for people who are generally healthy and want to stay that way, not the treatment of disease.
Anything clinical, including prescriptions, is delivered by independent, licensed healthcare providers through our telehealth partners. Those providers exercise their own medical judgment and are solely responsible for any evaluation, diagnosis, treatment, or prescription. OneTwenty does not direct or control their clinical decisions.
If you're managing a diagnosed condition, OneTwenty is not a substitute for your physician. We're a complement to the care you already receive, focused on helping you understand and improve the long-term inputs to your health.
Most members can use HSA or FSA funds for their OneTwenty membership. Your membership covers diagnostic lab testing and clinician review, which are generally eligible medical expenses, though final eligibility depends on your specific plan. If you pay with an HSA/FSA card, it works like any other card at checkout. If you don't have a card, or your plan requires documentation, we provide an itemized statement listing the services, the ordering provider, and the amount paid, which you submit to your plan administrator for reimbursement. We can't guarantee your plan's decision, so we recommend confirming with your administrator.
No, OneTwenty prioritizes natural interventions that escalate over time. We will start with lifestyle modifications, then supplements, and only then if needed do we prioritize medication intervention.
We are available in 49 states except for Rhode Island. In New York and New Jersey, there is an increased fee due to collection laws in place that don't allow us to use the Quest Network.
Your privacy and security are foundational to OneTwenty. We run on infrastructure and software built to HIPAA security standards, and we apply the same core safeguards used to protect data in regulated healthcare settings: encryption in transit and at rest, strict role-based access controls, and full audit logging of who accesses your information and when. We never sell your personal health data. You decide what you connect and share, and you can request deletion of your data at any time.
One year on the OneTwenty platform, which covers four lab draws: one comprehensive initial panel to set your baseline, and three custom follow-up panels based on your results. Any additional services are available separately at transparent pricing.
Currently, we do not support direct insurance billing for lab orders. We made this decision to protect our members from unexpected and excessive costs.
Here is why:
The "Medical Necessity" Requirement: Insurance companies typically only cover lab tests that are tied to a specific illness or diagnosis code (ICD-10). Because many of our panels are proactive and focused on longevity (preventive wellness) rather than treating an active sickness, they are frequently rejected by insurers as "investigational" or "not medically necessary."
The Cost Risk: If we submitted these orders to your insurance and they were denied, the lab would bill you their standard "retail price." This retail price can be 5x to 10x higher than the negotiated rates we have secured for you.
Our Solution: By operating on a self-pay basis, we guarantee you access to our heavily discounted wholesale rates, ensuring you know exactly what you are paying upfront with no surprise bills in the mail later.
We are working on it: We understand that using insurance is preferred for basic labs. We are actively working on a solution that will allow us to safely bill insurance for standard preventive tests while keeping advanced longevity markers separate. We hope to introduce this hybrid option in the future.
