China wholesale MK677 - Bodybuilding Andarine S4 Raw Sarms Muscle Growth Powder Losing Bodyfat CasNO.401900-40-1 – Hjtc

Product Name : Andarine(S4)

Andarine is an orally active partial agonist for androgen receptors. It is less potent in both anabolic and androgenic effects than other SARMs. In an animal model of benign prostatic hypertrophy, andarine was shown to reduce prostate weight with similar efficacy to finasteride, but without producing any reduction in muscle mass or anti-androgenic side effects.

This suggests that it is able to competitively block binding of dihydrotestosterone to its receptor targets in the prostate gland, but its partial agonist effects at androgen receptors prevent the side effects associated with the anti-androgenic drugs traditionally used for treatment of BPH.

Certain steroids are considered “cutting” steroids such as Winstrol and Anavar. These steroids don’t offer too much in large gains in muscle mass but are very effective in leaning out the body. The SARM S-4 has very similar properties.As S-4 shows this binding affinity to the AR, it demonstrates the similar fat burning effects. S-4 also shows a decrease in LPL (lipoprotein lipase) which is an enzyme that causes lipid accumulation.

S-4 also fits into a cutting protocol for the concurrent reduction in body fat with maintenance of muscle mass in a hypocaloric environment.
As S4 has both anabolic and androgenic effects in muscle tissue, it will not only help with fat loss, but maintain and even increase muscle mass when cutting.S-4 causes increases in vascularity and promote a very nice, “quality”, hard look to the users muscles, with little or no water retention.

In this way S-4 can be compared to Winstrol, without the harsh hair loss or extreme adverse effects on cholesterol.

Also other popular steroids/Prohormones used for cutting such as winstrol or epistane can have a notable effect on drying out of the joints. S-4 doesn’t suffer such consequences so the athlete is still able to lift heavy in order to maintain/increase muscle mass and strength.

Another advantage S-4 offers for cutting is that it doesn’t give the painful pumps associated with other popular steroids/Prohormones. Back and calf pumps are particularly detrimental for cutting as it limits the ability to perform cardio.

To start, let’s describe what a SARM does. There are three type of chemicals that act on the androgen receptor (AR). One is the an AR antagonist, which is a chemical that binds to the receptor to prevent it from activating. The second is an AR agonist, which binds to the receptor and detaches, then binds again, over and over. An example of an AR agonist is testosterone, each time the AR is bonded with testosterone, a signal is sent out to activate a particular set of genes. The more testosterone that is in the system, the more AR binding will occur. The third is an AR modulator, or basically a molecule that attaches to an AR and changes its structure to react however it wants.
