Normal Tertroxin dosages vary from one individual to the next. Anything from 20-100mcg per day can be used, but it should be individually determined by starting on 20mcg and increasing with 10mcg every three or four days. The intent of this slow buildup is to help the body become adjust to the increasing thyroid hormone levels, and avoid sudden changes that may initiate side effects. Cycles of liothyronine sodium usually last no longer than 6 weeks, and administration of the drug should not be halted abruptly. Instead, it is discontinued in the same slow manner in which it was initiated. This usually entails reducing the dosage by 10mcg every three to four days. This tapering is done so that the body has time to readjust its endogenous hormone production at the conclusion of therapy.
These types of steroids are generally made by non-licensed manufacturers and are not overseen by any regulatory board. Due to it becoming increasingly harder to obtain pharmaceutical grade steroids, most people opt for underground brands. The main problem with underground brands is no one knows what type of environment these steroids are produced in. They may or may not be produced in a sterile environment. There are however many big underground brands available that have hundreds of positive reviews, it is always best to stick with the big brands.
Once more, an early study done on S-4 provided proof of full muscle regeneration in volunteers with with degenerative disorders without the use of exercise and the minimum dosage of 3mg/kg/day. Changes can be seen anywhere from 1-2 weeks. This was the very first study classified S-4 as CLINICALLY SIGNIFICANT by improving skeletal muscle strength, lean body mass, and a reduction in body fat [Chen et al., 2005; Gao et al., 2005; Kearbey et al., 2007]. Unfortunately, there are always some side effects that arise when using Because S-4 is a ligand by definition, the side effects will never be permanent even at supraphysiological dosages and can be easily avoided through proper dosing.
