Dulaglutide (Dulaglutide (Trulicity))
A long-acting GLP-1 receptor agonist consisting of a GLP-1 analog fused to an IgG4 Fc domain. Approved for type 2 diabetes and shown to produce significant weight loss. Once-weekly dosing makes it convenient for adherence.
How it works
Activates GLP-1 receptors in pancreatic beta cells (enhancing glucose-dependent insulin secretion), the hypothalamus (reducing appetite), and the GI tract (slowing gastric emptying). The Fc fusion extends half-life to ~5 days.

Research
- AWARD clinical trial program (2017): Dulaglutide demonstrated superior A1c reduction vs placebo and non-inferiority to insulin glargine across multiple trials.
- REWIND cardiovascular outcomes (2019): Dulaglutide reduced major cardiovascular events (MACE) by 12% vs placebo in 9,901 patients over median 5.4 years.
- Dulaglutide weight effects in non-diabetics (2021): 4.5 mg dose produced 4.7% weight loss at 36 weeks in overweight/obese adults without diabetes.
Community reviews of Dulaglutide
- peptide_sarah rated it 4/5 - Finally broke through my plateau: Skeptical going in because I have been burned by hype before. Dulaglutide actually delivered though. The appetite reduction is subtle but persistent, you just stop thinking about food between meals. First two weeks were rough with some nausea and low energy, but I stuck with the low starting dose and let my body adapt. By week 3 I was feeling normal with clearly reduced appetite. By month 2, the results on the scale were undeniable. Key advice: start at the lowest dose, do not rush titration, eat protein-forward, and stay hydrated. The compound does the heavy lifting on appetite, you just ne
- injection_journal rated it 5/5 - Steady progress without the usual hunger: Been running Dulaglutide for about 2 months now and the appetite suppression is real. Not that awful "I cannot eat" feeling, more like the constant food noise just goes quiet. I actually forget about snacking, which never happened before. The first week had some mild nausea, especially after eating too fast or too greasy. Learned to eat slower and smaller portions and it resolved. Energy levels are good, no crashes or fatigue that some people report. Down about 10% body weight with no muscle loss that I can detect. Still hitting my lifts fine. The consistency is what impressed me most, no pl
- halflife_harry rated it 4/5 - Works as advertised once you titrate properly: I have tried a lot of weight management approaches over the years and Dulaglutide is the first that actually changed my relationship with food rather than just white-knuckling through hunger. The mental shift happened around week 2. Side effects were manageable. Some GI upset early on that settled by week 3. Mild constipation that fiber and water fixed. Nothing that made me want to stop. Results have been steady and sustainable. Losing about 1-2 lbs per week without feeling deprived. My energy is actually better than before, probably because I am not on the blood sugar roller coaster anymore
