Methyldrene is marketed as a fat‑burner / thermogenic supplement, labeled “25 Ephedra / ECA Stack.” According to a retailer listing, the container holds 100 capsules.
The formula reportedly includes a blend (“ECA stack”) containing: stimulant components such as Ephedra (or ephedrine‑type extract), caffeine, white willow bark (often source of salicylates), plus other herbal/thermo ingredients (green tea, cayenne, Citrus aurantium, etc.).
Boost in metabolic rate and fat burning (“thermogenesis”) when paired with diet and training.
Increased energy, alertness, and possibly suppressed appetite — helping support a calorie deficit.
Support for weight/fat loss, especially when combined with a calorie‑controlled diet and exercise.
Common recommendation: 1 capsule in morning + optionally 1 after lunch — total no more than 2 capsules/day.
Avoid late use (should not be taken close to bedtime) to prevent sleep disruption.
Because of the Ephedra (or ephedrine‑type) + high stimulant content, potential side‑effects include elevated heart rate, high blood pressure, jitteriness, insomnia, anxiety, digestive issues, possibly nausea or more serious cardiovascular stress.
Use requires caution — especially if you have underlying conditions (heart, blood pressure), or are sensitive to stimulants / caffeine.
According to reviews and analyses: many users report the stimulant “kick,” but results (in fat loss) vary widely; some say benefits are limited, others report unpleasant side‑effects (restlessness, sleeplessness, jitteriness, digestive discomfort).
There is controversy around ECA‑stack supplements: stimulants like Ephedra have been restricted or banned in many countries because of safety issues. Supplements containing ephedra/ephedrine often carry higher risk. Experts often caution against long‑term or high‑dose use.
As with any supplement: results are not guaranteed — fat loss requires a consistent calorie deficit + good diet + training. The supplement may “help a bit,” but it's not magic.
