German Pharmaceuticals S4 (Andarine) - 25mg

What it does?

S4 Andarine is a SARM compound that causes increased activity at androgen cells, leading to increased protein synthesis. A key property of S4 is preventing catabolism, making it perfect on a cutting cycle when a user is more likely to lose muscle, those taking s4 will find they will become more defined, vascular and perform better despite cutting.

What is it and How does it effect you?

SARM is short for Selective androgen receptor modulator, this means that they regulate the amount of activity that take place in your androgen cell, which are the cells within the body responsible for nitrogen retention and protein synthesis.

When these SARMS attach themselves to androgen receptors they allow for the maximum potential of that cell to be explored further than its current capability, enabling for better activity within the cell and an overall better performing musculoskeletal tissue.

S4 has around one-third of the binding affinity of testosterone to the androgen receptor, but also has the effect of making the user's own testosterone exert a greater effect than normal on protein synthesis and muscle mass. S4 is the most research SARM available, with multiple studies confirming its effects. S4 provides greater muscle building potential than DHT - the strongest male hormone men naturally produce.
While helping to build muscle, one of the side effects is that individuals actually lose body fat.
Actual amount of fat lost is dependant on the genetics of the user, but it increases the body's ability to oxidise fat. S4 also has the effect of “drying out” the muscle in the same way the anabolic steroid Winstrol would, which means it can be great as a hardener towards the end of a cycle or pre-contest.

Who should take it?

We do only advise S4 to men due to affinity of anabolic ratio with regards to testosterone production therefore women would not be advised to take this compound.

We also advise that those under the age of 21 do not take this product as it can hinder natural testosterone production and may cause issues and unwanted side effects such as trouble reproducing and returning testosterone back to a normal level.

How to take it?  

Although research on this is mixed, the general recommended dosage of S4 for many is 25-75mg a day, this is best split into one-three dosages to ensure that the compound remains fully active in your system and the full benefits are achieved.


Does it require Cycle Support?

As the product is unmethylated for it to be active it will evidentially not require any cycle support however it is anecdotally accepted that for high doses/long cycles a small cycle support is advised such as a milk thistle.

Post Cycle

It is not mandatory to run a post cycle therapy with S4 if you run your cycle under 6 weeks at 1-2 caps a day however we would still recommend using a testosterone booster. If you stacked S4 with another compound and/or ran it for an extended period of time we recommend using an advanced hormonal recovery agent.

    Have purchased S4 pills before with no vision sides - fake!. Getting vision sides with this - doesn't really bother me though as it is mild. But, the vision sides proves this is the real deal! Great product.

    Gaining Strength and keeping size while on a slow cut

    Posted by Unknown on 9th Jul 2018

    I've been lifting 10 years and added this to my cutting routine. I've kept size and actually gaining strength on a few exercises. Overall pretty good. Night vision issues was a worry at first but I got used to my eyes delayed adjustment. Only happened when I bumped it up to 75mg

    During a cut, lost weight but didn't lose much muscle, if any. Great for a cutting cycle and will use again. German Pharma's a great company and this site is super reliable.
