Carl read the papersWhat it actually is
Adipotide is a peptidomimetic that binds prohibitin, a protein concentrated on the blood vessels feeding white fat. It carries a second domain that triggers apoptosis — cell death — in those vessels.
The concept is unusual: rather than suppressing appetite or raising metabolic rate, it starves fat tissue of its blood supply so the tissue itself is lost. That mechanism is also the source of the problem, because the kidney is densely vascular and takes the same hit.
How it’s thought to work
- Prohibitin targeting — Homes to prohibitin on the vasculature supplying white adipose tissue.
- Targeted apoptosis — The attached pro-apoptotic domain kills those endothelial cells.
- Vascular pruning — Fat tissue loses its blood supply and is resorbed — independent of appetite.
- Off-target renal load — The same mechanism acts on renal vasculature, which is what ended the clinical programme.
What the research says
The 2011 Barnhart primate study is the famous one — obese rhesus monkeys lost roughly 11% of body weight in four weeks. Renal toxicity was described there as mild and reversible. It was not, in humans: the phase 1 clinical trial was terminated in 2019, with dose-limiting renal toxicity — raised creatinine and structural change in tubular cells. The therapeutic index is around 1.0, meaning the dose that produces meaningful fat loss is essentially the same dose that damages kidneys.
- Barnhart 2011 (rhesus primates) — ~11% body-weight reduction in 4 weeks.
- Renal toxicity in primates: glomerular injury, tubular atrophy, proteinuria.
- Human phase 1 terminated 2019 — dose-limiting renal toxicity.
- Therapeutic index approximately 1.0. There is no comfortable margin between effect and harm.

Reported protocols
These are the doses the peptide community actually reports running (Reddit & forums), alongside published research — logged for education, not as a recommendation to use.
| Parameter | Commonly reported range |
|---|---|
| Study protocol | Published work used 28-day cycles followed by a washout — long enough for fat reduction, intended to cap cumulative renal exposure |
| Circulating figures | 0.5 mg/kg/day for 28 days is widely repeated online. It is extrapolated from monkey studies and did not translate safely to humans |
| Lower figures | Some sources cite roughly 0.01 mg/kg/day as a more conservative research dose |
| Route | Subcutaneous |
| Monitoring | Every serious protocol calls for kidney function monitoring — creatinine and eGFR — from the first week |
| Community tip | The honest community position on this compound is largely do not run it. The people who have looked closely at the phase 1 termination generally conclude the margin is too thin to manage at home. |
Common use cases
| Goal | Community protocol notes |
|---|---|
| Adipose research | 28-day cycles with washout, per the published study design |
| Why it is not a fat-loss protocol | therapeutic index ~1.0 — no usable margin between effect and renal injury |
Mixing it (reconstitution)
Freeze-dried peptides must be reconstituted with bacteriostatic water before they can be measured. Carl’s calculator turns “mg in the vial + ml of water + target dose” into “units on the syringe” — and tells you how long the vial lasts.

Injection & handling
Published research used subcutaneous administration in 28-day cycles with a washout period between them. The far more important point is monitoring: renal function — creatinine and eGFR — is the parameter that ended the human programme, and kidney injury produces no symptoms until it is well advanced. Anyone handling this compound without baseline and ongoing bloods has no way of knowing what is happening.
Stacks it appears in
- Not applicable — Stacking is not a meaningful discussion for a compound whose dose-limiting toxicity is renal. Anything adding renal load makes the core problem worse.
