How do these two 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 YK11 will not only add extra lean muscle, but it will also produce the effect of myostatin (create new muscle) while preventing the loss of muscle mass during weight loss.

MK677 (Nutrobal) will cause a rise in IGF-1 and growth hormone even in a diet-induced nitrogen wasting state, which means it’s almost impossible not to gain lean muscle mass and lose body fat on MK677.  It will also aid in such things as endurance, mood, sleep, and general health. Hence, MK677 gives the athletes all the benefits of growth hormone and IGF-1 increase without the high financial cost and side effects of the HGH.

Having these three popular mass gaining Sarms working all together will guarantee some intense muscle gains, quickly!


What Gains will I get?

With the correct diet and taking the right amount of protein for your body weight, expect to see up to 6-10kg of lean muscle by 12 weeks. LGD is known for amazing protein synthesis so be sure not to skip your protein shakes!

Each Container contains 1000mg of Sarms. Total of 2 x LGD: 2000mg | 1 x YK11: 1000mg | 1 x MK677: 1000mg

All Redback SARMs are 99% pure raw powders with no fillers added to them.

Cycle for:
12 weeks.

Beginners: 10mg a day (1 levelled off micro scoop). With 2 x Containers of LGD, you will have 200 doses
Experienced: 20mg a day (2 levelled off micro scoops). With 2 x Containers of LGD, you will have 100 doses

YK11 :
10mg per day (1 levelled off micro scoop) This will last for 100 days.

MK677 :
Dose(Beginner): Start off with 10mg per day (5 levelled off micro scoops = 10mg) – This will last for 100 days.
Dose(Experienced): 20-25mg per day (10-13 levelled off micro scoops) – This will last for 50 days.

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.

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.


MK677: Take it right before bed for maximum effects and dreaming benefits. Mix it with your liquid of choice. MK677 has a strong taste so I would have it with a juice (you will regret having it with water)

MK677 Storage- Minimize open air exposure and store in a cool dry place. Each purchase will have a Silica Gel in the container. MK677 is hygroscopic meaning it will absorb moisture in the air which leads to the SARM forming into rocks then turning yellow and gooey (the good news is it doesn’t affect the potency and can still be used, the bad news is it will make it hard and annoying to dose). Keep the Silica Gel inside the container to keep this from happening.


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.
