How do these Sarms work together?
Taking LGD (Ligandrol) you are guaranteed on some solid lean muscle gains. It will drastically increase protein synthesis, glycogen storage, and blood flow. You will experience bigger pumps, longer workout and a faster recovery time.

Taking S4 will greatly increase fat loss and it will do just that very quickly! Andarine is very versatile and is often thought of as one of the stronger SARM’s, in terms of the many capabilities it has, it is a lean body mass builder as well as strength and vascularity enhancer.

Taking YK11 will not only add extra lean muscle, it will produce the effect of myostatin (create new muscle) while preventing the loss of muscle mass during weight loss.

Taking RAD140 will increase lean muscle mass whilst boosting your strength/stamina/endurance.

What do I expect to see from this stack?
Everything! Lean muscle gains, strength gains, burn fat, improved endurance, new muscle cells, faster recovery time, enhanced vascularity, joint/tendon healing

How and When to Take:
LGD: I usually take LGD before working out, that way I can mix the powder with my pre-workout. It doesn’t necessarily matter what time of the day you take LGD, just try to make sure you take it every day around the same time. It can be mixed with any liquid (eg water, juice) when taking so its completely up to you. If your taking 2 scoops of LGD – take them both at the same time.

S4: Andarine is recommended at doses of 20-40mg a day and has even been tolerated at 100mg, although it is highly recommended to start low and gradually increase dosage to keeps side effects minimal. It has a half-life of 6 hours, so I recommend you dose Andarine (s4) at least twice a day (1 scoop in the morning and another in the afternoon for 20mg dosage). The optimum length of Andarine cycles are said to be up to 8 weeks long and is not hepatotoxic, so unlike oral steroids and comparable drugs, longer cycles do not cause danger to the liver.

YK11: As its half-life is 24 hours just be sure to dose every day at the same time. Mix with any liquid of your choice, Orange juice tends to be a favourite.

RAD140:  Take a full dose once a day, same time every day. Mix with the liquid of your choice.


Post Cycle Treatment(PCT) should be done after cycling these SARMs for 12 weeks. From week 13 to 16 (4 weeks) I suggest taking Clomid just to keep safe from the suppressive sides.

Dosage for Clomid per week should look like this:
Week 13 – 50mg per day
Week 14 – 25mg per day
Week 15 – 25mg per day
Week 16 – 25mg per day

Or if you cant get your hands on Clomid try a great natural test booster like Test Stack Rx:


Each purchase comes with a 10mg micro scoop and a dosage instruction card.
