Dopamine agonist. Used to control prolactin on 19-nor cycles.

Effects: Lowers prolactin, powerful dopamine agonist. Used alongside Nandrolone/Trenbolone to prevent prolactin-related sides.

Synthetic thyroid hormone T3. Used in contest prep for metabolic boost.

Effects: Suppresses TSH, reduces T4 production, increases metabolic rate, can be catabolic without AAS, takes weeks for thyroid function to recover after cessation

Selective β3-adrenergic receptor agonist. Originally approved for overactive bladder (Astellas, brand name Myrbetriq). Increasingly used in fat-loss protocols for its ability to activate brown adipose tissue (BAT) thermogenesis without the β2-driven cardiac and tremor side effects of [Clenbuterol](/compounds/other-compounds/clenbuterol).

Effects: Activates brown adipose tissue thermogenesis, increases resting energy expenditure (~200 kcal/day at clinical doses), promotes browning of white adipose tissue, improves insulin sensitivity (BAT glucose uptake), may modestly improve HDL cholesterol. Mild blood pressure elevation, mild heart rate increase, urinary retention risk, dry mouth. No suppression of HPTA. No direct impact on liver enzymes at standard doses.

Beta-2 adrenergic agonist used as a bronchodilator and thermogenic fat-loss agent. Not an anabolic steroid. Widely used in contest prep and cutting phases for its metabolic and anti-catabolic effects.

Effects: Increases metabolic rate and core temperature, stimulates lipolysis, mild anti-catabolic effect, elevates heart rate and blood pressure, can cause electrolyte imbalances (taurine/potassium depletion), may worsen cardiac hypertrophy with chronic use
