Thyrobol

What is Thyrobol by Phoenix Remedies?

Thyrobol comes from Phoenix Remedies in a large pack: 100 pills of liothyronine at 50 mcg each. Twice the common 25 mcg strength and the high pill count make it a product for long preparation periods and for users who split tablets into 25 mcg halves.

The active ingredient, liothyronine, is synthetic T3, the thyroid hormone that actually does the work inside the cells. Once it binds to its receptors in the cell nucleus, it increases the production of proteins involved in energy metabolism, raises the number and activity of mitochondria, and speeds up the cycling of sodium and potassium across cell membranes, a process that consumes a great deal of energy. The net result is a higher metabolic rate and more heat.

Why use Thyrobol?

Every long diet ends up fighting adaptive thermogenesis: as body fat drops, the body lowers its T3, burns fewer calories and holds on to the fat that remains. Competitors in contest preparation use T3 to keep the metabolic rate higher for longer, so that progress does not stall in the final weeks. Because T3 also increases the breakdown of muscle protein, it is used together with high protein intake and, in many cases, anabolic steroids, which protect the muscle. In medicine, liothyronine replaces missing thyroid hormone in hypothyroidism.

How is it dosed?

Liothyronine leaves the body much faster than T4, so many users divide the daily amount into two portions, for example half a tablet in the morning and half in the early afternoon. That gives a steadier level and fewer peaks of palpitations and sweating. Common bodybuilding practice is to start with 25 mcg (half a Thyrobol tablet) a day, move to 50 mcg (one tablet) after about a week, and in some cases to 75 mcg. Courses usually last six to eight weeks, longer only under close monitoring, and finish with a slow taper.

At one tablet a day the pack lasts more than three months, enough for a full prep with breaks. A qualified medical professional must agree on the dose and the duration and check thyroid values and heart rate along the way.

Side effects

Thyroid hormone affects nearly every organ, so excess shows up in many places:

• heart: fast pulse, palpitations, raised blood pressure, irregular rhythm;
• nervous system: anxiety, irritability, tremor, insomnia;
• temperature: heat intolerance and heavy sweating;
• digestion: increased hunger, frequent stools or diarrhea;
• body composition: loss of muscle and strength as well as fat;
• bones: loss of bone density with long or heavy use.

The thyroid's own production is suppressed while T3 is taken. People with heart disease, adrenal insufficiency, or an untreated thyroid disorder should not take Thyrobol.
