S4 makes you feel more focused, it alters something mentally? I have never heard that before, but any edge is welcomed, I just DON'T like feeling cracked out, which is why I really avoid stimulants.
So you're going to be running Sarm Search's OSTA or S4 with anabolics next time? I keep asking and asking about this, and still have yet to receive an answer about whether or not taking SARMS while taking AAS would cause any diminished effect between the two if they act on the same receptor!?
If I had to take a very educated guess, I would say that SARMS actually enhances and does not inhibit the effects of AAS. If the use the same receptor, it is my understanding that SARMS will have more of an amplification effect rather than an inhibition effect because it binds to the receptor but does not prevent its uptake of other biochemicals ment for said receptor.
The way I like to think of it is the simple push-pull factor. The push is putting some sort of excess substance into your body, like AAS, and the push is how well your body receives this substance. Naturally, this pull can be deterred by a number of things (I would assume factors like genetics and age play a part), and SARMS helps adjust your pull so that you receive the substance MUCH better.
That is why it can work even without the effects of AAS in your system; it simply aids you to intake what you produce naturally rather than wasting your excess androgen.
Correct me if I'm wrong, but thats my explanation.
