The story
Why Replenexists.
The injections work. They also change what your body gets every day. This is what the founder saw in the people around them in Bali, and what we made for it.

What the injection changes
Less on the plate, every day.
fewer calories a day on these injections, measured in trials.

What people go through
The side effects nobody plans for.
Nausea, constipation, diarrhoea and vomiting were the most reported side effects in the large trials of today's injections (STEP 1, SURMOUNT-1). The quieter ones come in the weeks after: flat energy, a headache by day three, muscle going with the fat, hair shedding months later. Here is what people describe, and what actually helps.
Protein is hard when appetite is gone.
A normal 300 ml shake sits like a brick. People eat like a toddler and still need 1.2 to 1.6 g of protein per kilo a day. What helps: small, thin, high-protein servings you can finish.
The gut slows down.
The injection slows the stomach, and thick fibers like psyllium slow it further; nobody has tested the two together. What helps: a gentle, low-viscosity fiber, magnesium, water, and starting with half a serving.
The day-three headache.
Less food is also less water and fewer minerals, and people describe a headache by day three of a new dose. What helps: sodium, potassium and magnesium with the water you do drink.
A stomach that turns.
Nausea and sulfur burps, worst after a dose increase or a fatty meal. What helps: ginger has moderate to strong evidence against nausea in general, none yet with these injections, and we say so.
Muscle goes with the fat.
Twenty to thirty percent of the weight lost is lean mass. What helps: enough protein, strength training, and creatine, which has decades of evidence for keeping muscle.
Hair sheds months later.
Fast weight loss pushes hair into a resting phase, and it usually grows back. Nothing in a stick fixes that, and we do not claim it. Enough protein and nutrients over months is the honest support.
Why we made it
Give back what the injection takes.
"A GLP-1's best friend. So many people take it, and more will. But their bodies are missing things. I want to give back what it takes from them, from nature, in a good way."
The founder, Bali
The honest version: the injection does not pull nutrients out of you. It makes you eat 500 to 650 fewer calories a day, so protein, fiber, water, minerals and vitamins fall short, and 20 to 30 percent of the weight you lose is muscle. Replen puts those back, from sources you can name, in servings a small appetite can finish.

Honest by design
What we do not claim.
- We do not treat, cure or prevent anything.
- We do not replace meals or your doctor's advice.
- No detox, no cortisol, no miracle. Protein keeps muscle, fiber keeps the gut moving, minerals keep you hydrated, and that is the whole story.
- Not for pregnancy or breastfeeding. Keep the night stick one to two hours away from oral medicines.
