- Tesamorelin
Compounds shown are those explored within each program. Your intake shows which options suit a self-directed purchase, and where physician opinion is recommended.
How SEIVA works
Two clear paths. The right level of review.
Every journey starts with the same safety screening. Eligible options may proceed to self-directed Marketplace purchase. Physician opinions are coming soon; options requiring review remain restricted.
- 01
Choose your goal
Pick the pathway that matches what you want to improve.
- 02
Complete intake
Share your goals, health history, medications, allergies, and relevant safety information.
- 03
AI-assisted triage
Structured screening identifies self-reported risk factors. It supports routing; it does not diagnose or replace a clinician.
- 04
Follow the right path
Eligible options may proceed to Marketplace. Other options or risk factors require physician review.
Deterministic safety rules apply to every intake. AI does not diagnose or make medical decisions.
Research spotlight
View all research Clinical context, without the noise.
Concise summaries link to primary sources and keep evidence strength separate from individual clinical decisions.
Retatrutide
Investigational triple-receptor agonist
A 48-week phase 2 randomized trial studied retatrutide, an investigational GIP, GLP-1 and glucagon receptor agonist, in adults with obesity.
In a 48-week phase 2 trial, the highest dose group lost 24.2% of body weight on average, vs. 2.1% with placebo — investigational, not FDA-approved.
Tesamorelin
Growth hormone–releasing factor analog
A randomized trial in people with HIV and abdominal fat accumulation looked at tesamorelin's effect on visceral and liver fat.
In a randomized trial of people with HIV-associated abdominal fat, tesamorelin reduced visceral fat over 6 months — this result applies to that population, not the general population.
NAD+
Cellular coenzyme — not a peptide
A 2026 systematic review summarizes preclinical and clinical research on NAD+ supplementation for aging and wellness.
Clinical evidence is still developing: human IV-NAD+ studies to date are small pharmacokinetic/tolerability pilots, not proof of an anti-aging or performance benefit.
About SEIVA

- Mission
- Make peptide care easier to understand and navigate through transparent research, thoughtful screening and responsible clinical oversight.
- Vision
- A future where personalized health decisions are supported by better evidence, better data and appropriate human clinical judgment.
Is SEIVA physician-supervised?
SEIVA distinguishes the physician pathway from the self-directed Marketplace. Independent physician opinions are coming soon and are not currently available for new purchases. Marketplace orders are your own decision and are not reviewed by a physician. Eligible customers accept a Self-Directed Purchase Waiver before their first order. AI-assisted screening supports routing; it does not diagnose or replace a clinician.
How is SEIVA different from buying peptides online?
Structured safety screening is built into the journey. Marketplace purchases remain self-directed. Independent physician opinions are coming soon and are not currently available for new purchases.
Do I need a physician review to start?
No. Start by choosing a goal and completing the screening questionnaire, or go straight to the Marketplace if you already know what you want. An independent physician opinion is a separate service that is coming soon to SEIVA.
How will the physician opinion work?
Physician review is coming soon to SEIVA. When it launches, a licensed physician will review your intake and give you a written opinion on whether a protocol is suitable for you. Their opinion will be documented and kept as part of your record.
How are treatments delivered?
Availability, delivery times and handling requirements vary by destination. You are responsible for making sure the products you order can be lawfully imported and used where you live. Catalog stock does not establish permission to supply a product in your destination.
What happens after I start?
Your dashboard brings together your orders and account documents. Existing paid consultation customers can view their review status and any required next steps there. New independent physician opinions are coming soon.
What do SEIVA programs cost?
Each program is built around peptides selected for the quality of their evidence and how well they work together. Cost depends on the compounds you choose and the length of your protocol. Prices are shown on each product page. An independent physician opinion will be a separate, optional service — coming soon.
