Synthroid T4 General Info
Synthroid T4 is the first synthetic thyroid compound that was developed in late1950's. Synthroid T4 is FDA approved and accepted worldwide in clinical medicine, bodybuilding, and other sports. In clinical medicine, Synthroid T4 is the most prescribed medication for treating thyroid hormones insufficiency, called hypothyroidism.
Athletes and bodybuilders widely use T4 for its ability to significantly boost metabolic rate and initiate lipolysis.
Thyroid Physiology General Info (HPT axis)
Hypothalamus releases thyrotropin-releasing hormone (TRH).
Thyrotropin-releasing hormone (TRH) stimulates the pituitary gland to release thyroid-stimulating hormone (TSH)
TSH stimulates the thyroid to produce thyroid hormones T4 and T3.
Thyroid Hormones T4/T3
Thyroid hormones Triiodothyronine (T4) and Thyroxine (T3) are responsible for multiple processes in the body, such as:
- energetic metabolism and fluid balance
- utilization of protein by the body
- utilization of carbs and fat by the body
- linear growth and thermogenesis
- nervous and cardiovascular systems
- hepatic metabolism of nutrients and micronutrients
Thyroid hormones T4 and T3 insufficiency lead to weight gain, energy loss, lethargy, hair loss, and worsening of skin texture.
Synthroid T4 in Bodybuilding and other Sports
Bodybuilders use Synthroid T4 for metabolic rate stimulation and body fat breakdown.
Recommended dosage 150-300 mcg/day
Cycle Lenght 6-8 weeks
Please note
We strongly do not recommend starting Synthroid T4 or any other thyroid drugs at high dosages.
Synthroid T4 is a very potent hormone, and it is strongly advised to give your body some time to adjust to exogenous Synthroid T4. The best practice is to start at 75 mcg/day and gradually increase the dosage by 75 mcg every day. We do not recommend exceeding a 300 mcg/day dosage.
Synthroid T4 Hypothyroidism Therapy
The recommended dosage for thyroid hormones insufficiency is two mcg/kg/day.
Therapy Lenght 4-6 weeks
Possible side effects
Synthroid T4 overdose and misuse could lead to side effects such as sweating, increased bowel motility, headaches, and irritability.

Synthroid T4 and HGH
The prolonged intake of HGH at dosages above 4IU/day can affect the thyroid gland and cause hyperglycemia. We strongly recommend adding 75-150 mcg/day of Synthroid T4 into your HGH cycle to avoid adverse side effects of HGH on the thyroid gland.
