Due to Testosterone Propionate possessing a brief active-life of 2-3 days, many athletes involved in tested competitions liked the stuff…a lot. Testing is usually based upon testosterone /Epitestosterone levels. Though most individuals have a much lower ratio, athletes can have natural ratios of up to 6:1. This is considered a negative test for steroids. usually.

Melanotan 2 (also referred to as Melanotan II) is a synthetically produced variant of a peptide hormone naturally produced in the body that stimulates melanogenesis, a process responsible for pigmentation of the skin. This peptide hormone, called alpha-Melanocyte stimulating hormone or MSH, activates certain melanocortin receptors in the process of exerting its effects. Indeed, MSH also exerts potent influence over lipid metabolism, appetite, and sexual libido via these melanocortin receptors. As a result, Melanotan 2 has been shown in studies to exhibit appetite suppressant, lipolytic, and libido-enhancing effects in addition to promoting skin tanning. Melanotan 2 has been researched extensively for use in protecting against the harmful effects of ultraviolet radiation from sunlight due to its melanogenesis-stimulating properties.

GW501516 (Cardarine) doesn’t have any published human studies. In rodents, though, it shows great promise as an exercise mimetic – it lights up many of the same genes you’d activate by going on a run or lifting [4]. That alone wasn’t enough to make much of a change, but when researchers had mice take GW501516 with consistent exercise, results went through the roof:

Oxandrolone was often refereed to as an all purpose oral AAS. This drug was once marketed under the product name (still commonly used trade name) of Anavar. It has the unique quality of significantly stimulating (more than other AAS) the synthesis of phosphocreatine in muscle cells which in turn provides faster regeneration of, and a distinct elevation in, ATP. Of course all AAS have this effect to some extent. Oxandrolone is simply unmatched in this aspect.

Andarine has been one of the most widely tested and studied of all the SARMS. Tests have proven that Andarine helps retain lean muscle mass as well as enhancing it. However with Andarine this is not the only noted benefit. In addition to strength and lean muscle gains is its powerful fat burning properties as well.

Healthy men who took LGD-4033 for 21 days saw a significant increase in lean body mass. The only side effect was short-term testosterone suppression (more on that in a second) [3]. One milligram per day was enough to cause significant muscle growth. The higher the dose, the more muscle participants put on. In another trial, participants took doses as high as 22 mg/day with no side effects or safety issues [3].
