Description

−

T3 Genesis contains liothyronine sodium, a synthetic version of triiodothyronine (T3), the most active thyroid hormone. Medically it is used to treat hypothyroidism, some types of goitre and in thyroid testing. Because thyroid hormone controls metabolic rate, T3 is discussed in bodybuilding literature for fat loss during cutting phases, despite clear warnings against using thyroid hormones for weight loss in people with normal thyroid function.

Composition

+

Each tablet contains 25 mcg of liothyronine sodium, equivalent to the T3 hormone the thyroid gland produces. T3 acts directly on thyroid hormone receptors in almost every tissue, increasing energy use and heat production. Supplied as 100 Tablets.

Outcome

+
  • Medically used to treat hypothyroidism and certain thyroid conditions.
  • Frequently referenced for raising metabolic rate during cutting phases.
  • Can cause loss of muscle as well as fat when thyroid levels are pushed above normal.
  • Acts faster and clears faster than levothyroxine (T4).
  • Suppresses the body's own thyroid hormone production while it is being taken.
  • These are commonly discussed associations in community and research literature, not approved performance claims.

Side Effects

+
  • Fast or irregular heartbeat and palpitations.
  • Anxiety, nervousness, tremor and insomnia.
  • Sweating, heat intolerance and weight loss.
  • Loss of muscle mass at higher-than-normal thyroid levels.
  • Bone loss with long-term excess thyroid hormone.
  • This is not a complete list and should not be treated as medical guidance.

Important Safety Information

+
  • Boxed Warning: Thyroid hormones should not be used to treat obesity or for weight loss in people with normal thyroid function. Larger amounts can cause serious or life-threatening toxicity.
  • Contraindications: Do not use it with uncorrected adrenal insufficiency, an overactive thyroid (thyrotoxicosis), or recent heart attack.
  • Serious Risks: Heart rhythm problems, angina, bone loss and thyroid suppression.
  • Product Quality: This is a widely counterfeited product category. A product sold under this name may not contain what the label says, which adds a separate safety risk.

FAQ

What is T3 Genesis?

T3 Genesis is an oral tablet containing liothyronine, the synthetic form of the thyroid hormone T3, made by Genesis.

What is the difference between T3 and T4?

T4 (levothyroxine) is converted in the body into T3, the active hormone. Liothyronine is T3 itself, so it acts faster and clears faster.

Is T3 safe for weight loss?

No. Thyroid hormones carry a warning against use for weight loss in people with normal thyroid function because of serious heart and metabolic risks.

Is liothyronine approved?

Yes, it is approved for hypothyroidism and is sold by prescription, for example under the Cytomel brand.

Is it legal without a prescription?

No. Non-prescribed use is regulated or prohibited in most countries.
