In briefChecked October 2026
CalmLean is a caffeine-free fat burner based on ForsLean forskolin, cayenne, chromium and BioPerine. CortiSync is a stress supplement based on 300 mg of Sensoril ashwagandha. Neither finished product has been trialed. A placebo-controlled stress and cortisol trial backs CortiSync's main ingredient, whereas forskolin's weight-loss trials are small and mixed. On our overall assessment, that puts CortiSync slightly ahead.
⚡ The short verdict
We pick CortiSync here, chiefly because the evidence for its main ingredient is better for what it's sold for. For weight loss without stimulants, CalmLean is the product aimed at that goal, though the best case is a modest result. The full side-by-side breakdown follows below.
This PrimeGENIX stress supplement is built on 300 mg of Sensoril ashwagandha, alongside rhodiola, holy basil, lemon balm, magnolia, lychee and L-theanine. Doses are disclosed, but the product itself has not been tested.
Every dose is listed on CortiSync, and its Sensoril ashwagandha amount sits within the tested range. The finished product hasn't been tested, and ashwagandha doesn't suit everyone, so read the cautions in our full review first.
We choose CortiSync, mainly because its main ingredient has better evidence for the purpose it's sold for. CalmLean is the one aimed at weight loss without stimulants, but expect modest results at best.
CalmLean is a caffeine-free fat burner whose formula is ForsLean forskolin, cayenne, chromium and BioPerine. CortiSync is a non-stimulant stress formula with 300 mg of Sensoril ashwagandha at its core. The table above and each full review cover ingredients, evidence and cautions.
Ask a healthcare professional first. The ingredients don't obviously overlap, but each has cautions of its own: forskolin may lower blood pressure, and CortiSync's ingredients can cause drowsiness.
The official website is the surest route to the genuine product. A 67-day money-back guarantee is advertised, but the terms aren't confirmed. Marketplace orders may not be covered, so read the official terms before buying.
Talk to a qualified healthcare professional before you start either one, particularly if you take prescription medication or have a health condition. Both are dietary supplements sold over the counter, not medicines. Not intended to diagnose, treat, cure or prevent any disease. With CalmLean, forskolin may lower blood pressure and add to the effect of blood thinners, and chromium can lower blood sugar. With CortiSync, ashwagandha has been linked to rare liver injury and can affect thyroid levels, and drowsiness is possible from several ingredients.
