Although not technically an ‘anabolic steroid’, Tiratricol (T3) is one of the many forms of thyroid medication used by bodybuilders during the pre-contest phase of their training regime.
A naturally occurring metabolite of the endogenous (produced inside the body) hormone triodothyronine (T3), when used properly this drug has very significant fat burning properties. It is also one of the most effective and safe fat burning drugs available.

Tiratricol has proven to be exceptional for burning off excess body fat without the need to turn to extreme dieting methods – which can lead to long-term metabolic harm.


In order to utilize any thyroid medication to its fullest potential we need to first understand the way natural T3 functions in the body.

Thyroid hormones are the metabolic regulators in the body. When the level of T3 is high the metabolism is speeded up. This allows calories to be burned faster and the uptake of nutrients by the body to be increased. Supplemental T3 increases your body’s energy demands and allows you to burn fat at a greatly accelerated rate. However, it should also be noted that when it comes to obtaining fuel for this increase in metabolism your body might begin to turn to muscle tissue for fuel. With this in mind, it is usually recommended that when taking thyroid medication it is best to include an anti-catabolic substance to prevent muscle loss. For competitive bodybuilders this would mean that T3 use be accompanied by the use of non-aromatizing steroids such as stanozolol (Winstrol), Trenbolone and Primobolan. Using T3 along with Clenbuterol is also a popular pre-contest stack since Clenbuterol is reputed to have a muscle sparing effect.

Another popular way of effectively using T3 supplementation is to alternate its use with Clenbuterol. This usually takes the form of a cycle involving three weeks of Clen alternated with three weeks of T3. This form of cycle takes into account the fact that Clen often loses most of its benefits after a short period of time and alternating with T3 will maintain the fat burning process at a steady rate.


With so many synthetic thyroid preparations on the market you may be asking, “Why choose Tiratricol?”

The answer is that Tiratricol is by far the safest thyroid medication currently available. A relatively mild product, Tiratricol reaches maximum effectiveness at a daily dosage of about 1mg per 50lbs of bodyweight. It exhibits a half- life of approximately 6 hours; therefore daily dosage is best divided evenly throughout the day in order to maintain steady blood levels. In addition to this it is extremely important to point out that administration of Tiratricol will not lead to an uncontrollable increase in metabolic rate like other thyroid hormones. It will only create an increase reflecting the upper range considered normal and acceptable throughout administration. This increase is not only significant but also highly effective without creating the discomfort sometimes experienced when one uses other thyroid medications.


As is the case with any administration of exogenous (outside the body) thyroid hormone, it is strongly advised not to quit T3 use cold turkey. Daily intake should be reduced gradually in order to allow the body to resume natural hormone production as smoothly and swiftly as possible.

Although recommendations on the length of time you can safely remain on thyroid hormone vary widely (I have seen some reports of ‘safe use’ being 9-10 months a year!). It is usually considered safe to use for 15-20 weeks as long as low doses are utilized. However, an even safer option would be to keep use to 4-6 weeks in order to avoid any negative effects on natural thyroid function.

Leigh Penman, in addition to be a staff writer at MuscleSport Mag, has been writing for bodybuilding magazines, websites and nutritional supplement companies since 1985. Whilst residing in the UK, she earned the reputation of being one of the top female writers in bodybuilding-related media. Her credits included being a contributing editor on all the magazines in production as well as filling the shoes of Ladies Editor and Showbiz Editor on two publications (the later being on Arnold’s sanctioned magazine, ‘Bodypower’). During this time she also competed successfully on four occasions (placing in the top four in all contests).

Relocating to New York in the late 1990s she focused her writing attention to crystal healing techniques and metaphysics – however, she still maintained a five day workout schedule during this time and gained her personal training certificate.

Having also studied pharmacology in relation to sports performance, her writing began taking her in that direction until the present day which sees her embarking on a return to the magazine world, as well as extending her web-related work in the bodybuilding and fitness field.

Leigh has been working out for close to thirty years so she is clearly a writer who ‘walks her talk.’
