Peptide

Type

Orforglipron (Foundayo) is a non-peptide, small-molecule GLP-1 receptor agonist — not a true peptide — developed by Eli Lilly and FDA-approved in April 2026 for chronic weight management in adults with obesity or overweight with weight-related comorbidities. It is taken once daily as an oral tablet with no food or water restrictions, distinguishing it from injectable GLP-1 therapies. Phase 3 trials demonstrated up to 11.2% mean body weight reduction at the 36 mg dose over 72 weeks, along with significant improvements in blood pressure, lipids, and glycemic control.

Top researched benefits

Overview of Orforglipron

Orforglipron selectively binds and activates the GLP-1 receptor (GLP-1R) at a transmembrane allosteric site, stimulating glucose-dependent insulin secretion, suppressing glucagon, slowing gastric emptying, and reducing appetite via central hypothalamic GLP-1 pathways. It exhibits biased signaling — producing robust cAMP activation with low beta-arrestin recruitment — which reduces receptor internalization and may contribute to sustained efficacy relative to native GLP-1.

weight loss

  • ATTAIN-1 demonstrated 12.4% weight loss (27.3 lbs) at 72 weeks with 36mg dose; 59.6% achieving ≥10% weight loss.
  • ATTAIN-2 showed 10.5% weight loss with 72.8% achieving ≥5% weight loss.
  • Improvements in waist circumference, systolic blood pressure (8-12 mmHg), triglycerides (-20-30%).
  • 91% achieved near-normal blood sugar levels versus 42% with placebo.

type 2 diabetes

  • ACHIEVE-1 Phase 3 trial showed HbA1c reductions of 1.3-1.6% from 8.0% baseline; 76.2% achieving HbA1c <7%.
  • Significant improvements in insulin sensitivity indices within 4 weeks of therapy initiation.

Typical Dose

Titration: 0.8 mg (month 1) → 2.5 mg → 5.5 mg → 9 mg → 14.5 mg → 17.2 mg (month 6+); one step per month. Maximum maintenance dose is 17.2 mg once daily. Half-life range: 29–49 hours depending on dose.

Orforglipron Protocols

Orforglipron (Foundayo) is taken as a once-daily oral tablet and is the only GLP-1 receptor agonist pill that can be administered at any time of day without food or water restrictions. Its small-molecule, non-peptide structure provides oral bioavailability of approximately 79% and a half-life of 29–49 hours, eliminating the need for injection or cold-chain storage.

Reconstitution Instructions

Materials needed:

Orforglipron tablet (as prescribed strength: 0.8 mg, 2.5 mg, 5.5 mg, 9 mg, 14.5 mg, or 17.2 mg)Water for swallowing

Steps to reconstitute

  1. Swallow the tablet whole — do not crush, chew, or break it.
  2. Take once daily at any time of day, with or without food.
  3. Choose a consistent daily time and take orforglipron at that same time each day.
  4. If a dose is missed, take it on the same day as soon as remembered; if the next day has arrived, skip the missed dose and resume the regular schedule — do not double up.
  5. Store at room temperature (15–30°C) in the original packaging away from moisture and heat; no refrigeration required.
  6. Follow the monthly titration schedule: 0.8 mg for at least 4 weeks, then 2.5 mg, then 5.5 mg (lowest therapeutic dose), then increase further to 9 mg, 14.5 mg, or 17.2 mg (maximum) as tolerated.

Orforglipron Cycle

The Orforglipron Cycle section explains how long a typical cycle lasts and what to expect during each phase. Over time, your body can become less responsive with continuous use.

Taking breaks between cycles may help maintain effectiveness and support better overall results.

Appetite reduction typically within 1-3 days; mild to moderate nausea common
Week 2-4
Gradual weight loss begins (0.5-2 lbs per week); improved blood sugar control
Week 4-12
Reduced food cravings; GI adverse effects generally diminish; metabolic markers improving
Week 12-36
Continued progressive weight loss without plateau
Week 0-0
Long-term therapy well-tolerated; sustained benefits at 72 weeks

Frequently asked questions

What is a peptide dosage calculator?

A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringeunits to draw. This calculator works for single peptide compounds and multi-peptide blends.

How do I calculate peptide dosage from a vial?

To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.

How much Bacteriostatic water should I add to a peptide vial?

Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.

How are peptides different from proteins?

Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.​
