It was once commonly used during PCT in the belief it will aid testosterone restoration, however this is flawed due to its mechanism of action. The drug mimics the effects of LH in the body, stimulating the Leydig cells to produce testosterone in the testes . This can be fruitful in rectify existing, or avoiding testicular atrophy on cycle. It will not aid the process of recovery in the post cycle phase however, as the drug will bring about heightened oestrogen levels due to the greater aromatising of the testosterone being produced in the testes , thus bringing about greater inhibition of the HPTA .
Anavar & Primobolan note: These are two of the most commonly counterfeited steroids on the market. Any anabolic steroid can be counterfeited, but as these are two of the most sought after, counterfeiting is a bit more common. Their high demand further increases the cost of these two steroids, and if purchasing a counterfeit that can make it even more disappointing. It is not uncommon for Anavar to be low dosed Dianabol and for Primobolan to be nothing more than testosterone as Dianabol and Testosterone are two of the cheapest steroids to make.
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.
