What the injection changes
fewer calories a day. That is how much less people eat on these injections in trials.
Nature Medicine, 2025of the weight lost is muscle, not fat, unless protein and strength training keep it.
Body composition review, 2025protein per kilo of body weight a day is what the 2025 joint clinical advisory recommends.
American Journal of Clinical Nutrition, 2025Less food means less protein, less fiber, less water and fewer minerals and vitamins, every day. Most people feel it as flat energy, a slow gut and a headache by day three. Replen puts the missing pieces back, in servings you can actually finish.

The gentle fiber that does not slow your stomach further.

Transparency
Every ingredient is listed like this: what it is, which form, how much, why it is in, and where it comes from. Supplier and country of origin for each one are published with the first batch, together with the lab report. Until then the cards show the planned formula.
Clear whey isolate, from milk
18 g protein per stick, plannedKeeps muscle while you eat less. The 2025 joint advisory asks for 1.2 to 1.6 g protein per kilo a day; a small plate rarely gets there.
Sodium and chloride from seawater
Amount on the packPeople on injections drink less and lose salt with it. Sodium is the electrolyte that stops the day-three headache.
Coconut water powder, for potassium
Amount on the packPotassium for hydration, from the fruit rather than a salt. It also gives the morning stick its light, fruity base.
Magnesium from seawater
Amount on the packThe third electrolyte. Part of the hydration set, at a gentle daytime dose.
Acerola cherry extract
Daily-value level, plannedVitamin C from a fruit, not from a factory, because the dose allows it here.
Forms set with the manufacturer, printed on the pack
Daily-value levels, plannedA smaller plate carries fewer vitamins. These are the ones a full plate would have given you. B6 is also studied for nausea.
Ginger root
250 mg per stick, plannedA calm stomach. Nausea is the most common side effect in the first weeks on an injection, and ginger is the best-studied food for it.
Partially hydrolysed guar gum (PHGG)
5 g per stick, plannedThe gentle fiber. Thick fibers slow the stomach, and so does the injection; this one keeps the gut moving without doing that.
Magnesium bound to glycine
150 mg magnesium per stick, plannedThe form that is easy on the stomach. Calm in the evening, and a gut that moves in the morning.
Creatine monohydrate
3 g per stick, plannedMuscle is what you lose fastest on these injections, and creatine has decades of evidence for keeping it. It is made in a factory, not grown, and we say so.
Chamomile flower and ginger root, for flavour
FlavourWarm, not sweet. No sweetener does the work of a flavour here.
Certificate of analysis from an independent laboratory
Published online per batchWhat is on the pack is what is in the pack. The report for every batch goes online, and the batch number on your box finds it.
Planned formula. Final amounts are set with the manufacturer and printed on the pack. This product is a food and does not replace meals, medication or your doctor's advice.
Small enough to finish
A normal shake is 300 ml of creamy liquid. Ours is 200 ml and clear as juice.
Half a night stick on a sensitive day, two on a slow one.
Start with the first injection week, when the side effects begin, not after.
Honest by design
