Real peptide medicine, real weight loss.
GLP-1 peptide therapy — compounded and branded — prescribed online by US-licensed doctors. No insurance hoops, no chatbot triage.
GLP-1 (glucagon-like peptide-1) is a hormone your gut releases after meals to quiet hunger, slow gastric emptying, and improve how your body uses glucose. GLP-1 peptide medicines — semaglutide and tirzepatide — are engineered versions of that signal. In pivotal trials, weekly semaglutide produced roughly 14–15% body-weight reduction at 68 weeks (STEP 1, NEJM 2021), and tirzepatide — a dual GIP/GLP-1 co-agonist — reached 18–22% at one year (SURMOUNT-1, NEJM 2022). These are the largest weight-loss effects ever recorded in a chronic weight-management trial.
Peptide12 offers every credible GLP-1 path — compounded semaglutide and tirzepatide for cash-pay flexibility, plus FDA-approved branded pens (Wegovy®, Ozempic®, Zepbound®, Mounjaro®) when your insurance covers them. Every protocol is reviewed by a US-licensed prescribing doctor, dispensed by state-licensed compounding pharmacies or FDA-registered outsourcing facilities, and shipped overnight in temperature-controlled packaging.

“Down 42 lbs in 7 months on compounded semaglutide. The doctor adjusted my dose three times based on how I was tolerating it — felt actually managed, not just shipped a vial.”

Patient feedback
“Came over from Wegovy because my insurance dropped coverage. Same active ingredient, a third the price, same results. Wish I’d switched sooner.”

Patient feedback
“Tirzepatide. 38 pounds in 5 months, A1C from 6.7 to 5.6. Bloodwork ordered before I started, again at 90 days. Real protocol, not a vending machine.”
Mason F.

Patient feedback
“Wegovy covered through my insurance — Peptide12 handled the prior auth and I had the pen in two weeks. Doctor replied to messages same day, twice.”
Ines L.

Patient feedback
“Finished my titration on compounded tirzepatide, transitioned to a maintenance dose. Lost 34 lbs total. My doctor walked me through the maintenance plan before I asked.”
Theo R.

Patient feedback
“First GLP-1. The MD spent 20 minutes on the intake video call walking through side effects and what to watch for. Started low, no nausea, easy ramp up.”

Frequently asked questions
Most patients without insurance coverage choose compounded semaglutide or tirzepatide because the cost is significantly lower than the branded equivalent, and the active ingredient is identical. If your insurance covers Wegovy, Ozempic, Zepbound, or Mounjaro, the branded option is usually preferable. Your doctor will help you compare.
In published trials, patients on weekly semaglutide lost roughly 14–15% of body weight at one year (STEP 1, NEJM 2021). Tirzepatide trials showed greater reductions, around 18–22% at one year (SURMOUNT-1, NEJM 2022). Most patients see noticeable changes within 8–12 weeks as the dose titrates upward. Individual results vary based on dose, adherence, diet, and physical activity.
The active ingredient (semaglutide or tirzepatide) is the same molecule. Branded products are manufactured in fixed-dose injector pens. Compounded versions are prepared by 503A pharmacies under individualized prescription, which allows more flexible dosing, useful when a patient needs a dose between standard pen strengths or has specific clinical needs the branded product cannot accommodate.
Peptide12 partners with state-licensed compounding pharmacies that hold state and federal licensure and undergo regular USP <797> sterility audits. Every batch is third-party tested for identity, potency, sterility, and endotoxin before release. Compounded medications are not FDA-approved as finished drug products, but they are prepared from FDA-regulated active pharmaceutical ingredients under individualized prescription.
Yes. Baseline labs (metabolic panel, HbA1c, lipid panel, thyroid panel) are reviewed by your prescribing doctor before a prescription is issued. Recent labs (within 12 months) can be uploaded; otherwise we coordinate at-home or in-network draws.
Published data (STEP 4, JAMA 2022) show that most patients regain a portion of lost weight after discontinuation. Long-term success typically involves either continued treatment, transition to a maintenance dose, or a structured lifestyle plan, discussed with your doctor toward the end of your active titration.
Yes. There are no minimum commitments. You can pause or cancel before your next shipment from your patient portal or by messaging your care team.
