Social media’s power to create overnight trends is undeniable — but sometimes, those trends come with hidden dangers. This year, a mysterious blue box labeled “Molecule” went viral across Russian TikTok, capturing the attention of thousands of young users eager for a quick weight-loss fix.
Clips flooded feeds with captions like “Take Molecule and forget food exists” and “Do you want to sit in the back of the class in oversized clothes?” Teenagers proudly displayed their fridges stocked with shiny blue boxes marked “Molecule Plus,” sharing their “weight-loss journeys” for views and validation.
But behind the promises of a slimmer figure lies a serious public health concern — one that experts say could turn deadly.
⚠️ What Exactly Is the “Molecule” Pill?
“Molecule,” often branded as “Molecule Plus,” was sold online through unofficial marketplaces and Telegram groups. Its sellers claimed it was an herbal slimming supplement, safe and natural. But independent lab analyses have revealed something far more alarming — the pill actually contains sibutramine, a prescription-only stimulant banned in many countries due to its dangerous side effects.

😰 The Side Effects That Shocked Users
Maria, a 22-year-old from St Petersburg, thought she had found a shortcut to confidence. After taking two pills daily for two weeks, she experienced dry mouth, total loss of appetite, and intense anxiety.
“I had absolutely no desire to eat or drink. I was constantly nervous and chewing my cheeks,” Maria recalled.

Others shared similar experiences on TikTok — tremors, insomnia, dilated pupils, and severe panic attacks.
According to local Russian reports, at least three schoolchildren were hospitalized after taking the pills.

💊 What Makes Sibutramine So Dangerous?
Sibutramine was once prescribed for obesity, but it was withdrawn from markets after studies linked it to heart attacks, strokes, and psychiatric disturbances.
When used without medical supervision — especially by teenagers — it can cause dangerous spikes in blood pressure, irregular heartbeat, and severe mood swings.

🧠 Why Teens Are Falling for It
Experts say the Molecule craze exposes a deeper issue — the toxic pressure of online beauty standards.
Social media algorithms reward “before and after” content, and influencers often promote quick fixes that seem effortless. For many teens, the promise of instant results outweighs the hidden risks.

🕵️♀️ How It Slipped Past Regulations
Despite containing a banned ingredient, Molecule was openly sold on popular e-commerce sites and Telegram channels in Russia. Authorities have since issued warnings, and some online stores removed the listings — but new versions, such as “Molecule Plus” or “Atom,” quickly appeared.

This cat-and-mouse pattern is common in the black market for weight-loss drugs, where unscrupulous sellers rebrand products to evade regulation.
🩺 What Health Experts Recommend

- Consult a licensed doctor or nutritionist before taking any supplement.
- Report suspicious online sellers or unregulated products to health authorities.
- Focus on sustainable, evidence-based approaches: balanced diet, exercise, and medical supervision.
