Synephrin – Ephedrine

Each capsule contains ephedrine, a sympathomimetic stimulant that raises metabolic rate and core temperature through thermogenesis. It also blunts appetite and lifts training energy, which is why it is used almost exclusively during cutting phases rather than for size or strength. It is not a hormonal compound, so it works through the nervous system rather than the endocrine system.

Users commonly start with a low dose such as 25mg once in the morning with food, then step up to a split dose across the day once tolerance is assessed, staying within a low daily total. This is general guidance based on common practice, not medical advice, and total daily intake should not be pushed higher just because effects feel mild at first. Doses are usually kept away from the afternoon and evening to avoid disrupting sleep.

The most commonly reported effects are a faster heart rate, higher blood pressure, jitteriness or anxiety, and trouble sleeping if taken too late in the day. Because it acts directly on the cardiovascular system, resting heart rate and blood pressure are worth checking before starting and periodically during use. Anyone with existing heart or blood pressure issues should be especially cautious.

Ephedrine is not a steroid and does not suppress natural testosterone production, so a post cycle therapy protocol is not required for this product on its own. Liver support is generally more relevant to oral anabolic compounds than to a stimulant like this one, though staying hydrated and keeping cycles short is still sensible practice. If you are running it alongside oral steroids, follow the PCT and support plan appropriate to those compounds instead.

Ephedrine is considerably stronger than caffeine on its own and produces a more pronounced thermogenic and appetite-suppressing effect at a much lower dose. Many users pair a small amount of caffeine with it, a combination often referred to as an EC stack, though this compounds the cardiovascular load and is not something to take lightly. It should be treated as a short, defined-duration tool for a cutting phase rather than a daily long-term stimulant.
