Liothyronine Sodium (T3) is a synthetic version of the T3 thyroid hormone—the active form of triiodothyronine naturally produced by the human body. T3 dramatically enhances metabolic rate, helping burn fat at an accelerated pace, especially when combined with a calorie-restricted diet.
In bodybuilding, T3 is a go-to cutting compound, often stacked with anabolic steroids or fat burners like Clenbuterol to strip away fat while preserving muscle.
β Increases metabolic rate for rapid fat loss
β Helps maintain lean muscle during cutting cycles
β Boosts energy, stamina, and overall athletic output
β Enhances definition and vascularity
β Works synergistically with Clenbuterol, anabolic steroids, and HGH
Starting Dosage:
25 mcg/day (split into 1–2 doses)
Typical Cycle Range:
25–75 mcg/day, do not exceed 100 mcg/day
Cycle Length:
4–6 weeks max to prevent thyroid suppression
Tapering Required:
Always ramp up and taper down to avoid rebound effect
Cycle Tip:
Combine with Testosterone, Anavar, Winstrol, or Clenbuterol for optimal fat-burning effect
Fat Loss Stack: T3 + Clenbuterol + Winstrol
Pre-Contest Stack: T3 + Tren A + Test Prop + Masteron
Thyroid Support Stack: T3 + HGH + mild anabolic
Female Stack: Low-dose T3 + Anavar (supervised use only)
T3 is very powerful and must be used carefully to avoid thyroid-related complications:
Heart palpitations or rapid heartbeat
Excessive sweating
Insomnia or anxiety
Muscle loss if not stacked properly
Suppression of natural thyroid function
β
Always taper off
β
Use anabolic support to prevent catabolism
β
Monitor thyroid levels if used long term
Not suitable for people with thyroid conditions or heart problems
Not intended for off-season bulking
Never exceed 6 weeks of continuous use without medical oversight
Not recommended for natural athletes or those being drug tested
High doses or misuse can result in:
Severe tachycardia
Hyperthyroidism symptoms
Intense muscle catabolism
Risk of permanent thyroid suppression
β
Always begin at low doses
β
Carefully taper up and down
β
Never run without a clear cycle plan
Week | Effects You'll Notice |
---|---|

"T3 took my prep to the next level. I dropped 2% body fat in 3 weeks." — Leo, 33
"Works best when stacked with Clen and Anavar. Energy up, bodyfat down." — Sara, 29
"You have to taper it. But with Test and Winstrol, it shredded me fast." — James, 37
Q: Can I take T3 without steroids?
πΈ It's possible, but muscle loss risk is high. Always combine with anabolic support to protect lean mass.
Q: Do I need to taper off T3?
β
Yes. Always reduce dosage slowly to allow natural thyroid recovery.
Q: Is T3 safe for women?
β
At low doses (12.5–25 mcg/day) and under supervision, many women use it successfully during prep.
Q: Does T3 burn muscle?
β Not directly — but without anabolics or protein support, it can trigger catabolism.
Q: Is PCT needed after T3?
β No traditional PCT needed, but allow your thyroid to recover naturally and consider natural support supplements post-cycle.
