How many days does one bottle of Burn XT last?

The sum is short. A bottle has 60 capsules. Divide by the capsules you take each day. That gives you the days.

The catch is that your day count depends on which printed direction you follow. The bottle label and the sales listing do not match, and the difference changes how long a bottle lasts.

The last row is the ceiling on the label. At that dose a bottle is gone in about two weeks, and you take far more caffeine each day. Staying lower means a bottle lasts longer and costs less per day. See how to take Burn XT for the directions in full.

How long do the 1, 3 and 6 bottle packs last?

The same sum works for the packs. Each pack is a multiple of the 60-capsule bottle.

Your build-up week stretches a pack slightly, because you take one capsule a day for that week instead of two. The seller's pack table does not count that week, so treat the day figures as the plain case.

Which pack matches the 60-day window?

Think about what you are really buying. You are testing a product you may not have tried. The 60-day money-back window is your test period. A pack should last at least that long, or you cannot finish the test.

One bottle runs out at day 30. That is half your window. Three bottles last 90 days, so they cover the whole window with a month left. Six bottles last 180 days, and most of that time falls after you can claim a refund.

That is why the seller recommends the 3-bottle pack first. The seller also says the 6-bottle pack is the most ordered, and the one it earns most on. That candour is worth noting. If you already know the capsule suits you, a bigger pack is a fair choice. If you do not, the middle pack matches the decision.

How long does one dose of Burn XT last?

People also ask how long Burn XT lasts in the body, so here is the plain answer. Different parts of the formula work on different clocks.

• Caffeine peaks in the blood at about 30 to 60 minutes, and its effect lasts a few hours (Rudelle and colleagues, 2007).
• Capsaicinoids from the Capsimax extract act in the hours after a dose.
• Carnitine and the added effect of green tea catechins build up over weeks, if they do anything at all.

Exact hours for any one person are not published. Your own body weight, caffeine habit and sleep all change it. What the label gives you is a rule of thumb: stay six hours clear of sleep. Research on 400 mg of caffeine found it still cost measurable sleep when taken six hours before bed (Drake and colleagues, 2013).

As for how long before you notice anything, the seller's review records most often mention 3 to 6 weeks. That is a good reason to avoid a pack that ends before then.

Does Burn XT expire, and how should you store it?

A best-before date is printed on the base of the bottle, next to the lot code. The seller says it should be comfortably in the future when your parcel arrives, not weeks away. A date that close is usually a sign of old stock from somewhere else.

How many months a bottle stays good from the day of manufacture is not published in the seller's paperwork, so we do not state one. Check the date on your own bottle.

Storage is simple. Keep it cool and dry, out of reach of children, and out of a hot car. The bottle is opaque because catechins break down with light, and heat does the same, only faster. A bathroom windowsill is a poor spot. A kitchen cupboard away from the hob is a good one.

Do not use a bottle with a broken or missing safety seal. Call +1 (520) 206-1597 and the desk will replace it.

Will a bottle refill itself on a subscription?

No. There is no subscription. Every order placed through burnxts.com is a one-time payment, and nothing recurs. So there is nothing to cancel, and a bottle will not turn up unasked.

If you are being billed again and again for something described as Burn XT, it did not come from the official order link. Call the order desk with the order ID, or contact your card issuer.

Frequently asked questions

Where do these facts come from?

Our view

Our view is that you should pick the pack by the test, not by the bargain. If you have never taken it, 90 days of capsules gives you a fair 60-day test and a buffer. A single bottle ends before the wait most buyers describe, which is a poor fit for judging it.

If you already know how you respond to caffeine and the capsule, a larger pack is your choice to make. Just remember that return postage is yours, and that four months of a six-bottle pack fall outside the window.

Plan the dose first, then the pack. Our guide to what Burn XT costs and what is not published covers the money side, and the guarantee steps cover the refund route.
