EPI S-20 by Core Labs X: Epistane plus NAC and Vitamin E
When it comes to orally administered muscle-building supplements that have minimal side effects and significantly improve physique—that is, ensure a gain in high-quality muscle mass without water retention or fat accumulation—competitive and recreational bodybuilders immediately think of Epistane (2,3a-epithio-17a-methyletioallocholan-17b-ol). And rightly so! Epistane is a methyldihydrotestosterone prohormone that became known as a designer steroid at the beginning of the prohormone era in the 1990s under the name "Havoc." Because it hinders the aromatization of testosterone into estrogen, it is often referred to as an aromatase inhibitor (AI), which is not entirely accurate. Epistane is primarily an anabolic steroid—albeit one that only causes moderate mass gain. At the same time, it improves definition by increasing the rate of fat loss and, thanks to its antiestrogenic effect, also has a dehydrating effect.
What makes EPI S-20 RX from Core Labs X special?
EPI S-20 from Core Labs X is not pure Epistane, but a multi-ingredient complex. It consists of 20 mg Epistane, 250 mg N-Acetyl-L-Cysteine (NAC), 10 mg Vitamin E TPGS, and various minerals such as zinc, magnesium, potassium, and calcium. The product is suitable for both prohormone beginners and experienced athletes – the latter can stack EPI S-20 with aromatizing anabolic steroids to achieve a more dry body. (Caution: Epistane should not be stacked with other oral anabolic steroids. Oral anabolic steroids are generally highly toxic to the liver, and Epistane, as a 17-alpha-alkylated prohormone, is already a burden on the liver.)
