Head to head
Evolv GLP-1 vs Calocurb
These two are the closest thing the category has to a controlled experiment in claim hygiene. Both are premium, both are caffeine-free, and both hang everything on one proprietary active aimed at the same gut-hormone pathway. The difference is what you can check. Calocurb’s ingredient has multiple published, registered, peer-reviewed human appetite trials, including one that found nothing — a null result you can read for yourself. Evolv’s evidence is an unpublished 8-week interim readout on its own blog, advertised as "up to 12+ lbs" when the reported group average was −2.87% body weight. Calocurb also costs less and will refund you; Evolv is the most expensive product in our set and refunds nothing.
Evolv GLP-1
A genuinely novel idea wrapped in the category’s worst claim hygiene: "up to" headlines several times the actual averages, an unpublished and unpowered interim readout, the highest price in our set, and no refunds.

Frequently asked
Which one has better evidence, Evolv or Calocurb?
Calocurb, and it is not close on verifiability. Its Amarasate ingredient has several randomized, double-blind human trials published in journals and registered with a trial registry, and an independent university group has tested it too (finding no effect on energy intake at the 250 mg dose, which is worth knowing). Evolv has no peer-reviewed publication on the finished product and we found no trial registration; its data is an interim readout the company published itself and, in its own words, one that is not yet statistically powered.
Why is Evolv more expensive than Calocurb?
We can only report the prices, not the reasoning. Evolv is $148 for 30 servings, about $4.93 a serving. Calocurb is $89.99 for 90 capsules: about $2.00 a day at one serving, or roughly $4.00 a day at the full four-capsule protocol. Calocurb also offers a 30-day money-back guarantee on first orders, while Evolv states it cannot issue refunds once an order is placed.
Do either of these contain GLP-1?
No. Neither is GLP-1 or a GLP-1 drug, and neither should be treated as equivalent to one. Calocurb uses a bitter hops extract intended to trigger the gut’s own hormone release. Evolv says its engineered peptide interacts with GLP-1 and GIP receptors directly, which is a bigger mechanistic claim and the one with the least evidence behind it.
