Thyroxyl (T3) is used as a prescription medication to treat the common health problem of hypothyroidism which is where the thyroid gland is unable to produce enough thyroid hormone for normal functioning of the body’s metabolism.
Thyroxyl (T3) Structure
As the metabolism is largely controlled by the thyroid hormone, hypothyroidism causes a slow metabolism and results in weight gain, fatigue and a range of other health issues.
It’s the effects on the metabolism that made T3 appealing to athletes and bodybuilders. Most of all, the potential for accelerated fat loss by boosting the metabolic rate. Only when used with a diet that’s calorie restricted, combined with a proper exercise regime will t3have benefits for losing fat.
Another similar hormone is T4, however T3 is considered much more powerful. It is available both as a pharmaceutical product and on the black market. It comes most commonly in tablet form, although injectable is also available however is not common or recommended. To legally obtain T3 via a pharmacy you require a prescription.
Thyroxyl (T3) Benefits
As you might expect, the main benefits of T3 relate to its relationship with the metabolism as a thyroid hormone. Regulation of the metabolism is what this thyroid hormone does in the body and when it is not functioning as it should, a person can have great difficulty in losing weight and often finds themself putting on weight without explanation.
This tells us that T3 provides positive benefits for promoting an efficient metabolism that is working optimally for fat loss, and this is the main reason you will choose to use this drug. Let’s look at the specific benefits of T3:
T3 comes with great benefits for losing fat, but there’s a catch to be aware of: it has no direct anabolic activity and it’s very likely that you will also lose lean muscle while supplementing with T3. As the higher metabolic rate continues, the body needs more energy to burn and it will not take a preference for burning fat; therefore many users report loss of muscle.
This is a major issue for bodybuilding and athletic users who will not want to be losing muscle tissue. To avoid this problem, the majority of T3 users will want to add an anabolic steroid alongside T3 to act as a protective anabolic compound to assist with retaining muscle.
Many can make the mistake in thinking that you need to substantially increase the dosage of Cytomel for performance enhancement compared to a standard dosage range when it’s being used to treat hypothyroidism, but this is not the case. As long as you’re not suffering a hypothyroidism condition, using the recommended medical dosage will still provide benefits. 25mcg per day is a standard starting dose for medical use of Cytomel.
T) Dosage for Fat Loss
Fat loss is the only reason for using T3 outside of medical use and your dose for fat loss can either remain steady throughout a 6-12 week cycle, or gradually increase and then decrease throughout. In any case it’s wise to start low at 25mcg daily.
A dose of 50mcg to 75mcg daily is more than sufficient for the vast majority of users. In rare cases, advanced users might consider increasing this to 100mcg daily, however the increased risk of more serious side effects should not be underestimated at such a dosage.
Female Thyroxyl (T3) Dosage
Females are not known to require a different dosage level of T3 than men. Women can safely use T3 at 25mcg daily and see noticeable results. With overall body mass being the only difference between men and women when it comes to T3 use, women are unlikely to want to exceed 75mcg daily as a maximum dose and few will see the benefit of raising the dosage above that level, with 50mcg daily being sufficient for most users.
Thyroxyl (T3) Administration and Timing
The maximum length of time to continually use Cytomel should be no longer than 10 weeks. Most users will find that even 6 to 8 weeks provides good results, while others have extended the cycle out to 10 weeks or even 12 weeks; however this carries with it the risk of the thyroid becoming more dependent on this external source of hormone as well as serious side effects, and is not recommended.
It’s wise to lower your dose for the last week so the thyroid gland has time to adjust and so you don’t suddenly drop into hypothyroidism after stopping Cytomel. The ideal dosage for the final week is 25mcg daily. The dosage can be taken once per day and ideally is taken at a similar time each day so you are maintaining a consistent supply of the hormone.
Thyroxyl (T3) Cycles
Using T3 on its own in a cycle is very simple. If you’re a first time user it’s highly advisable to start at the lowest dose, then increase the dose as the cycle progresses, followed by a decrease back down to a low dose towards the end of the cycle.
This allows you to assess your reaction to T3, including side effects. By decreasing the dose for the final portion of the cycle the body can adjust back to regular thyroid hormone function without the drug. This is not absolutely critical and most people can happily get through a cycle of T3l at their chosen higher dose for the entire duration, with an abrupt end.
However, for your first cycle it’s recommended to use this pyramid strategy. An example beginner T3 only cycle follows:
Week 1-2: 25mcg daily
Week 3-7: 37.5-75mcg daily increased by 12.5-25mcg each time
Week 8-10: Decrease the dosage back down to 25mcg
This cycle can be run for a shorter period of just 8 weeks with dosages adjusted accordingly. Regardless of your daily dosage, you can take the entire dose in one administration each day as there is no need to split the dose.
