WE GOT THE ANSWERS

How does S4 Andarine work?

Andarine is one of the newer SARMs. S-4 is considered to be more potent when compared to other similar SARMs such as LGD-4033. It is very effective at lower doses and can significantly increase levels of lean muscle mass while reducing body fat levels. S-4 is renowned for increasing vascularity to give the ‘chiselled’, sharp look all bodybuilders seek to achieve.

Andarine is known for building muscle mass and bone density. Stick to lower doses to avoid side effects (some unwanted side-effects such as temporary night-blindness have been reported but only at very high doses!).

Can I stack S4 Andarine with other SARMs?

S-4 is commonly stacked with Tesofensine & MK2866 for improved fat loss and strength. It can also be stacked with most single compound sarms.

How should I dose Andarine S-4?

2 capsules or 1ml for full dosage with cycles generally lasting 12 weeks.

Should I PCT?

Yes, we always recommend a PCT after each cycle. Here are two of our favorites below!
