CalmLean

Description of the article « CalmLean »

Quick Answer

CalmLean is a stimulant-free thermogenic fat burner in capsule form from PrimeGENIX (a Leading Edge Health brand), formulated for men. Its formula is short and named — four ingredients, including the patented ForsLean® and BioPerine® — but only one amount (chromium, 0.200 mg) is published in the maker's page text; the other three doses exist only inside a supplement-facts label image. Every study the maker cites is of the ForsLean® ingredient, not of CalmLean itself, and the maker's own sales page twice pastes in sales copy for a different product. It costs $59 a bottle under a 67-day guarantee. We score it 5.5/10.

Quick Reference

Our Verdict

CalmLean's pitch — fat-burning support without caffeine or stimulants — is a reasonable one for men who want to avoid the jittery end of the diet-pill shelf, and its ingredient list is built from recognizable parts, two of them patented and standardized. What holds the score down is everything the maker leaves unverifiable. Three of the four ingredient amounts never appear in readable text, so you cannot tell whether the studied ingredient is present at a meaningful dose. The evidence is ingredient-level only, with the headline study's sample size unpublished. The guarantee, read closely, covers only the unused portion and deducts shipping — less generous than the maker's own retail page describes. And a sales page that twice tells you to buy a fruit-punch pre-workout instead is not the paperwork of a maker checking its own work. Buy it, if you buy it, as a stim-free experiment judged inside the guarantee window — not on the strength of its headline claims.

Sub-scores

• Ingredients: 6.0/10 — Four named ingredients, two of them patented and standardized (ForsLean® at 10% forskolin, BioPerine® at 95% piperine); but only chromium's amount is published in the page text — the other three doses appear only in a label image.
• Evidence: 5.5/10 — Ingredient-level only: the maker cites six clinical studies of the ForsLean® compound, headlined by an 8-week study with a specific reported result — but no trial of CalmLean itself, and no sample sizes published.
• Maker credibility: 5.0/10 — An established Leading Edge Health brand with verifiable store pricing; docked for another product's sales copy pasted twice into this product's page, the product name spelled two ways on one page, and a guarantee conflict between the maker's own pages.
• Safety: 5.0/10 — A caffeine-free, stimulant-free formula and a maker statement of no reported adverse side effects; but no warnings, exclusions or contraindications are published anywhere — nothing on medication, blood pressure, pregnancy or under-18 use.
• Value: 5.5/10 — $59 a bottle (about $1.97 a day) with a published pack ladder and a $49 subscription; docked because the guarantee covers only the unused portion and deducts shipping, and the effective doses you'd actually be paying for can't be checked.

What Is CalmLean?

CalmLean is a daily capsule fat burner positioned for men whose metabolism slows with age — the brand copy describes it as "scientifically tailor-made for men struggling to lose weight." Its headline claims, in the maker's own words, are "Lose At Least 1 Pound Each Week Or Your Money Back," a "100% Stim-Free Way To Lose Weight," "Boosts Metabolism Within Minutes," "Reduces Hunger" and "Blocks Fat Formation." The brand FAQ goes further, saying users can "lose anywhere between 10 to 20 pounds in just 60 days." The maker also sells it as working "without changing your current diet, exercise routine or lifestyle." Those are the maker's claims, quoted so you can see exactly what is being promised; what stands behind them is ingredient-level evidence, examined in the sections below. The page is endorsed by Dr. Kaleb Redden ("Doc Thor"), whom the maker identifies as the PrimeGENIX team doctor — a named endorsement, though from the maker's own team rather than an independent reviewer.

Key Ingredients

The formula has four ingredients, all named on the brand page. Only one amount is published in the maker's page text: chromium, 0.200 mg. The amounts for the other three appear only in the supplement-facts label image, not in readable text on the brand page — and the maker's retail page (Natural Health Source) does not state them either. Any website quoting you exact milligram doses for the other three is not reading them from the maker's published text.

• Chromium (as Chromium Polynicotinate) — 0.200 mg — the one dose the maker publishes in text.
• ForsLean® (Coleus forskohlii root extract — 10% Forskolin) — the patented lead ingredient, a standardized extract; its amount is not published in the page text. This is the ingredient the maker's cited studies are about.
• Cayenne Pepper (Capsicum annuum fruit) Powder — amount not published in the page text.
• BioPerine® (Black Pepper seed extract — 95% Piperine) — a patented absorption enhancer; amount not published in the page text. The maker claims it is "shown to increase bioavailability by 30%" — an ingredient claim, not a CalmLean result.

What We Like

• A genuinely stimulant-free formula. The maker states the formula is 100% natural, caffeine-free and stimulant-free — a real point of difference for men who avoid the stimulant-heavy end of this category.
• Two patented, standardized extracts. ForsLean® is standardized to 10% forskolin and BioPerine® to 95% piperine, so at least the identity and strength of those extracts are specified, even where their doses are not.
• Ingredient evidence with a specific headline result. The maker cites six clinical studies of the ForsLean® compound, including an 8-week study in which participants lost an average of 1.14 lb of body weight every 7 days — a concrete, checkable-style claim, even though the sample size is not published and the study is of the ingredient, not this product.
• Transparent, verifiable pricing. The full ladder — $59 / $169 / $319 and a $49 monthly subscription — is published on the maker's store page, and a 60-capsule bottle is a clear 30-day supply at the stated dose.

Good to Know

• The maker's page sells you the wrong product — twice. The CalmLean brand page twice contains the line "Click 'Add to Cart' now and experience the explosive difference of Nitric Pump – Fruit Punch Flavor" — order copy pasted in from the maker's pre-workout page (reviewed on this store as PrimeGENIX Pre-Workout (Nitric Pump)).
• The maker's retail page has copy errors of its own. The Natural Health Source CalmLean FAQ contains a whole pasted block about a different product ("Why is CortiSync superior to other supplements?") plus duplicated CalmLean ordering answers.
• The guarantee terms conflict between the maker's pages. The retail page says you can return the bottles "even if they are entirely used" for a full refund with no shipping deduction. The brand page — which governs by our source rule — says the unused portion in the original container, refunded minus shipping. Plan around the stricter version.
• Three of four doses are image-only. Amounts for ForsLean®, cayenne and BioPerine® appear only in the supplement-facts label image, never in the maker's text, on either the brand page or the retail page.
• The name itself is spelled two ways — "CalmLean®" and "Calm-Lean™" — on the same brand page.
• Read the side-effect lists carefully. The long lists of diet-pill side effects on the page describe other stimulant products, not CalmLean; the maker's statement about CalmLean itself is that there are "no reported adverse side-effects."

Who Should Not Use It

The maker publishes no exclusion list for CalmLean. No warnings or contraindications appear on the brand page or the maker's retail page — nothing on pregnancy, under-18 use, prescription medication, or blood pressure, even though this is a weight-loss product aimed at older men, a group commonly on medication. The maker's safety language is entirely positive: "no reported adverse side-effects," 100% natural, caffeine-free, stimulant-free. An absence of published warnings is not the same as an absence of risk, and the maker provides no guidance for anyone whose situation is not the standard case. If you take prescription medication, manage blood pressure, blood sugar or any other condition, are pregnant, or are under 18, talk to a doctor before using it — the maker won't raise any of these subjects.

Where to Buy

Buy only from the official site so the guarantee applies: the official CalmLean store. One bottle is $59; 3 bottles are $169 and 6 bottles are $319. A subscription is $49/month — the maker shows the regular $59 struck through — with free shipping in the USA and Canada, cancellable or changeable anytime. (The store header's "Buy Once from $53" is the per-bottle price inside the 6-bottle pack, not a single-bottle price; and older listings showing $59.95 / $169.95 / $319.95 are stale — the current store prices above are the maker's.) No MSRP is published for this product. Note the guarantee's fine shape before ordering: on the brand page's terms you return the unused portion within 67 days and shipping is deducted, so judge the product early in the window.

FAQ

Has CalmLean been clinically tested?
No trial of the finished product is cited. The maker cites six clinical studies of its lead ingredient, the patented ForsLean® compound — headlined by an 8-week study reporting average weight loss of 1.14 lb every 7 days. The maker does not publish that study's sample size on its pages.

How much of each ingredient is in it?
Only one amount is published in the maker's text: chromium, 0.200 mg per serving. The amounts of ForsLean®, cayenne pepper and BioPerine® appear only in the supplement-facts label image, not in text on the brand or retail pages.

How do I take it, and how long does a bottle last?
Two capsules with water, once a day. One bottle holds 60 capsules — a 30-day supply.

How much does it cost?
$59 for one bottle, $169 for three, $319 for six, or $49/month on subscription. No MSRP is published.

Does the guarantee cover a full trial?
Partly, and read the brand page's terms: a 67-day money-back guarantee, but you return the unused portion in the original container and the refund is minus shipping. The maker's retail page describes more generous terms (used bottles, full refund); the brand page governs, so don't count on the generous version.

Is it really stimulant-free?
Per the maker, yes: the formula is stated to be 100% natural, caffeine-free and stimulant-free, with no reported adverse side effects. The maker publishes no warnings or exclusions at all — if you take medication, ask a doctor first.

Also Consider

• CortiSync — the same maker's cortisol-balancing formula for men: seven adaptogens led by patented Sensoril® ashwagandha, aimed at the stress side of weight and energy, reviewed on this store.
• PrimeGENIX Testodren — the maker's flagship testosterone-support formula for men over 40, if supporting testosterone rather than thermogenesis is your goal.
• PrimeGENIX Pre-Workout (Nitric Pump) — the maker's pre-workout powder, for training-day energy and pumps rather than daily fat-burner capsules.
