Is LSC100 any good? What people who actually use the lozenges say

Last updated November 2026. Review figures checked on November 2, 2026.

The fastest way to find out if a product is any good is to hear from people who paid for it. Here is what LSC100 buyers say, the good and the not-so-good, with links so you can read the reviews yourself.

Short answer

Most people who review LSC100 rate it highly. On takelsc.com, the product page shows 43 reviews averaging 4.9 out of 5 as of November 2, 2026 [1]. The things reviewers mention most are fast energy without jitters, convenience, and taste. The most common complaints are about price, one of the two flavors, and that it takes a few minutes to melt.

What do reviewers like?

Energy without the jitters

This is the theme that comes up most often. One reviewer said it gave them the right amount of caffeine to feel locked in without feeling jittery [1]. Another, after a couple of weeks of use, described the energy as smooth, with no jitters or afternoon crash [1]. A third said it felt like a good cup of coffee without the jitteriness of an energy drink [2].

Speed

Several reviewers say they felt it quickly. One student wrote that they were surprised how fast it hit before an early class [1]. One reviewer was more specific: the lozenge takes a few minutes to melt, and the effect kicked in after about 10 minutes, depending on tolerance [1]. LSC says it hits in about 5 minutes [1], so expect some variation.

Convenience

People like not needing a cup, water or a coffee run. One customer said they never have time to brew coffee between meetings and keep it on hand for that reason [1].

What people use it for

From the reviews, people use LSC100 for:

• Studying, especially late at night [1]
• Workouts, as a pre-workout [1]
• The afternoon slump, as a second coffee [1]
• Cutting back on nicotine, in one reviewer's case [2]
• Avoiding coffee stains, in one reviewer's case, who swapped regular coffee for the Cold Brew flavor [1]

What do reviewers not like?

Honest reviews include the downsides. The ones we found:

• Taste of the Cold Brew flavor. One customer did not like it as much as Fresh Mint. LSC sent them Fresh Mint as a free replacement, and they said it tasted better [1].
• Price. The same customer called a 30-dose pack a bit pricey, though worth it at one a day [1].
• Melting time. It is a lozenge, not a chew. It takes a few minutes to dissolve [1].
• It is not medication. One reviewer pointed out that it does not act like ADHD medication, and noted it is not advertised that way [1].

How long does one dose last?

Reviewers mostly report a few hours. One said a single dose lasted about 3 to 4 hours [1]. LSC says 3 to 5 hours, depending on your metabolism [1].

Can you see the reviews yourself?

Yes. Written reviews are on the takelsc.com product page [1]. LSC also keeps a collection of verified buyer reviews and a collection of video reviews:

So, is it any good?

If you want caffeine that is fast, portable and sugar-free, most reviewers say yes. If you are sensitive to price, buy the smallest pack first. If you are unsure about taste, start with Fresh Mint or the Combo, which includes both flavors. LSC's Happiness Guarantee offers a full refund or exchange if it is not for you [1].

If you want to know what the research says about the "no jitters" claim, not just what reviewers feel, we covered that here:

FAQ

Which flavor do reviewers prefer?

Opinions split. Some reviewers prefer the coffee taste of Cold Brew, while at least one preferred Fresh Mint, and another liked that Fresh Mint works like a breath mint [1].

Do people get a crash afterward?

Most reviewers say no. Several specifically mention no crash [1]. Caffeine affects people differently, so your experience may differ.

How many should I take the first time?

LSC recommends starting with one, and waiting 15 to 20 minutes before taking another [1]. Do not take more than 4 in 24 hours [1].
