What I Found on the Product Page

SlimSet is a capsule supplement marketed for weight loss. The seller discloses three active ingredients by name: Caffeine Anhydrous, Green Coffee Bean, and Green Tea Extract. However, the product page provides almost no detail about serving size, total capsules per bottle, or amounts of the green coffee and green tea ingredients.

The only ingredient amount listed is 138 mg of Caffeine Anhydrous per capsule. This is important because it tells you how much stimulant you'd be taking in each dose. The page does not disclose how many capsules are in a bottle or how many you should take per day.

The Ingredient You Can Verify

Caffeine Anhydrous is a well-studied form of caffeine. Research shows it can improve focus and athletic performance, especially in short bursts of high-intensity activity. Several peer-reviewed studies found that 3–6 mg of caffeine per kilogram of body weight improved jumping performance and reduced fatigue during sprints and strength training.

At 138 mg per capsule, SlimSet's caffeine dose falls within the range studied in those trials. However, this does not mean SlimSet will help you lose weight. Caffeine may increase energy and alertness, but the scientific link between caffeine alone and fat loss is weak.

The other two ingredients—green coffee bean and green tea extract—are often promoted for weight loss. the seller does not disclose how much of each is in the formula.

To understand whether those ingredients might work for you, you'd need to know the exact amounts. That information is not on the product page.

What the Seller Does Not Tell You

This is where things get thin. The product page is missing several pieces of standard supplement label information:

• Serving size (how many capsules per serving)
• Servings per container (total capsules in the bottle)
• Amounts of Green Coffee Bean and Green Tea Extract
• Full ingredient list (whether there are filler ingredients, and if so, which ones)
• Allergen warnings
• Manufacturer name and location

Without this information, you cannot compare SlimSet to other caffeine supplements or know whether the formula contains anything you're sensitive to. This is a red flag if you need detailed label information before buying.

Who Should Not Use SlimSet

The seller explicitly warns against use in these cases:

• If you are pregnant or nursing
• If you are under 18
• If you are sensitive to stimulants
• If you have heart disease or high blood pressure (without medical supervision)

The seller also recommends taking the supplement earlier in the day because of the caffeine content. This makes sense—caffeine taken late can interfere with sleep.

If you take medicines, the seller advises consulting your doctor before using SlimSet. Caffeine can interact with some drugs, and without knowing the full ingredient list, you cannot assess the risk yourself.

The Sales Claims vs. What Science Shows

The product page includes testimonials claiming results like 9 pounds lost in 3 weeks, increased energy, and loose pants. These quotes come from the seller's own website, not from independent sources or clinical trials. The seller does not provide evidence that SlimSet itself caused these results.

The page also includes quotes from people saying they were initially skeptical but became convinced after watching a sales presentation. These are marketing statements, not product endorsements based on third-party testing.

I found no clinical trial data for SlimSet as a formula. Caffeine is studied, but the combination of caffeine, green coffee bean. green tea extract in these specific amounts has not been independently tested that we can verify here.

Pricing and the Money-Back Guarantee

SlimSet pricing varies by package size. When we checked the seller's page:

• 2 bottles (60-day supply): $158 ($79 per bottle)
• 3 bottles (90-day supply): $207 ($69 per bottle)
• 6 bottles (180-day supply): $294 ($49 per bottle) — labeled “Most Popular” with free shipping

Prices may change. Promotions run for limited periods. Check the current offer before checkout to confirm the exact total, shipping cost, and any applied discounts.

The seller offers a 60-day money-back guarantee if you're not satisfied. This is a refund policy, not a safety guarantee. It means you can return the product for your money back within 60 days.

To start a return, contact their support team by email at [email protected] or by mail to SLIMSET. PO Box 12730, United States. Orders typically ship within 5–7 business days in the US after processing.

What This Supplement Is Not

SlimSet has not been evaluated by the FDA. The FDA does not approve supplements the way it approves drugs. The seller's disclaimer states: “Statements found on this website have not been evaluated by the Food and Drug Administration. Products on this website are not intended to diagnose, treat, cure, or prevent any disease.”

This means SlimSet is not a drug and makes no drug claims. It is a dietary supplement. Weight loss results depend on many factors: diet, exercise, sleep, stress, and genetics. A supplement alone does not cause weight loss.

Before You Buy: Your Checklist

If you are considering SlimSet, here are the facts you should confirm:

• Ask yourself: Am I sensitive to caffeine? 138 mg per capsule is a moderate dose, but sensitivity varies widely. If you typically avoid caffeine or have heart or blood pressure concerns, discuss this supplement with your doctor first.
• Know your allergies: The product page does not list allergens. If you have food sensitivities, contact the seller before ordering to ask about ingredients and manufacturing.
• Understand the label: You cannot see the full supplement facts label on the page we reviewed. Ask the seller to send you the complete label before buy, or request it in your first package. Learn more about how to read a supplement label.
• Set realistic expectations: Caffeine improves alertness and energy. Green tea and green coffee extracts have some research behind them, but amounts matter. Without knowing the doses of those two ingredients, you cannot predict results. No supplement alone creates weight loss without diet and activity changes.
• Check the current offer: Prices, bundles, shipping, and promotions may have changed since this article was written. View SlimSet details and confirm the final cost and terms at checkout.

Pricing, bonuses, and shipping terms were observed at the time of this review and may change or vary. Different pages or offers may show different terms. Check the official product page for current terms before buying.

The Bottom Line

SlimSet is a caffeine-based supplement with minimal label transparency. The one ingredient we can verify—Caffeine Anhydrous—is well-studied and safe for most adults at this dose. However, the seller does not disclose amounts of the other two active ingredients or provide clinical evidence that SlimSet causes weight loss.

If you want a straightforward caffeine supplement for energy and focus, this may appeal to you. The 60-day return policy removes some financial risk. But if you need full ingredient transparency, independent testing. proof that a formula works for weight loss, SlimSet does not offer that level of detail.

Before ordering, review the current product page yourself. Compare the price and package options to other caffeine supplements. And if you are pregnant, nursing, under 18, sensitive to stimulants, or managing a heart or blood pressure condition, check with your doctor first.
