Semaglutide · Tirzepatide
01 / Body Composition
Body Composition
For people serious about metabolic change. GLP-1 and GIP receptor agonists work at the brain level — the same molecular class behind the most-studied weight management compounds in modern medicine. Physician-prescribed.
From $349 / mo
Sermorelin · CJC-1295 · Ipamorelin
02 / Performance
Performance & Strength
Built for athletes, lifters, and high-output operators. Growth-hormone secretagogues work with your pituitary — supporting natural GH pulsatility, sleep depth, and recovery between sessions. Studied, prescribed, compounded.
From $249 / mo
Enclomiphene · Kisspeptin · Sermorelin
03 / Hormones
Hormones — men & women
Optimize the signaling — keep the source. Peptide-based hormonal support that nudges your own LH, FSH, and GH pathways. For men: preserves fertility while supporting endogenous testosterone. For both: central hormonal cadence. Not hormone replacement.
From $229 / mo
NAD+ · Tesamorelin
04 / Longevity
Longevity & Healthy Aging
For people thinking in decades, not months. NAD+ and Tesamorelin target the cellular machinery behind energy, repair, and metabolic resilience. The protocol your future self will thank you for.
From $349 / mo
BPC-157 · TB-500
05 / Repair
Repair & Recovery
Built for the body that gets used hard. BPC-157 and TB-500 have been studied for their role in tissue homeostasis — connective tissue, gut lining, and the soft-tissue networks that take the most wear.
From $199 / mo
Selank · Semax · DSIP
06 / Focus
Focus & Mood
For minds that need to perform without crashing. Selank and Semax are nootropic peptides studied in cognitive and stress-modulation research. Sublingual, no needles, no stimulants.

Why Lior
The difference,in every shipment.

We compete on rigor, not marketing. Click any row to see the detail. Verified against publicly disclosed practices of typical telehealth peptide vendors.

Standard
Lior
Typical telehealth
503A-licensed US compounding pharmacy
Lior: Every prescription is dispensed from a state-licensed, FDA-registered 503A pharmacy operating under USP <797> sterile compounding standards. Others: Many telehealth vendors source from offshore "research chemical" suppliers without pharmacy licensure or fall back to 503B outsourcing facilities not authorized for patient-specific compounding.
Independent batch testing (potency & sterility)
Lior: Every batch passes third-party HPLC potency, endotoxin, and sterility testing before release. Certificate of Analysis available on request for any prescription. Others: Most vendors rely solely on the manufacturer's self-reported COA — if any is provided at all.
Pen, vial, and sublingual options
Lior: Choose pre-dosed pens (no math, no mixing), sterile vials with pre-measured syringes, or fast-dissolving sublingual strips for the needle-averse — same physician oversight, same pharmacy. Others: Most ship vials only and expect you to reconstitute and dose yourself.
Cold-chain shipping included
Lior: All injectables ship in temperature-controlled, insulated packaging with tracking. Free 2-day delivery nationwide. Others: Standard ground shipping is common — peptides degrade rapidly above 8°C and lose potency before they reach you.
No membership or subscription fees
Lior: You pay for the prescription, the physician's care, and the medicine. No annual membership, no platform fee, no surprise charges. Others: Many require $99–$299/year membership fees on top of medication costs.
Cancel or pause anytime
Lior: Adjust, pause, or cancel directly from your dashboard — no phone tree, no retention specialist, no questions asked. Others: Many require email or phone cancellation, lock you into 3-month minimum commitments, or auto-renew without notice.
Dedicated physician (not a rotating queue)
Lior: You're matched with one Lior physician who knows your case, reviews every refill, and adjusts your protocol based on your data. Others: Most platforms route messages to a shared pool of contracted prescribers — every refill is a new doctor.
Unlimited messaging with your physician
Lior: Message your physician any time — questions, side effects, dose changes — included in every protocol. Others: Most charge $25–$75 per message, $99+ per video consult, or limit messaging to billing questions only.
Transparent dosing & protocol details
Lior: Every label states the active ingredient, concentration, fill volume, and lot number. The complete protocol — peptide, dose, frequency, and rationale — is in your dashboard. Others: Some ship "proprietary blends" without per-ingredient quantification.

Our medical team
Physician-led.Always.

Every Lior patient is reviewed by a US-licensed physician who designs the protocol and monitors progress. Lior physicians are independent providers operating through their own professional corporations and licensed in the states we serve.

Our medical team is being onboarded for the soft launch. Named providers, credentials, and state-by-state coverage will appear here as physicians complete onboarding and confirm participation in writing. We don't list physicians who haven't signed on.

The science
A category,not a trend.

Peptide therapy isn't new. It's a recognized category in modern medicine with decades of clinical research, dozens of FDA-approved drugs, and a body of peer-reviewed evidence that's grown faster every year for the last decade. Here's what the published data actually shows.

100+
FDA-approved peptide drugs

Marketed today across endocrine, metabolic, oncology, and reproductive categories — including GLP-1 agonists (Semaglutide, Tirzepatide, Liraglutide), GHRH analogs (Tesamorelin), GnRH analogs, and dozens more.

Mechanisms, indications, safety profiles, and clinical trial results — across every major peptide class. Search "peptide therapeutics" on PubMed for the live count.

How peptides differ

Peptides are short chains of amino acids — the same molecules your body already uses to signal between cells. Unlike small-molecule drugs that block or force a pathway, peptides modulate existing signaling. Think tuner, not switch.

The published trials

Phase 3 trials of GLP-1 receptor agonists (STEP 1, SURMOUNT-1, published in NEJM) document mean body-weight reductions of ~15–22% over 68–72 weeks. Mechanism: peptide-receptor binding modulates appetite signaling at the brain level. Outcomes vary by patient.

Why compounded

503A pharmacies prepare patient-specific doses pursuant to a valid prescription. This lets your physician titrate to your individual response — different from off-the-shelf retail medications. Compounded medications are not FDA-approved; they are prepared on a patient-specific basis.

Lior protocols are physician-prescribed for individual patients; outcomes vary. See compounded-medication and off-label disclosures in our footer.
