This product is an exceptional value – 4th time buying. High dosage, yet about half the price of competing products.

Having a superior research cycle with this GH. Good work keep it up sarmtec!
Seth (verified owner) –
I researched the heck out of this stuff and was super glad to see this growth hormone and igf-1 stimulator in capsule form and very reasonably priced. It’s only been 3 days so I can’t report on experiment’s results but I can say the price is really good for a 90 day supply and the shipping was super fast too (to Indiana).
maverick (verified owner) –
Really impressed with the GH release, I’m positive this and rad was subject’s best sarm stack ever. Solid company.
cranecreek (verified owner) –
Seriously legit! 16 days so far into my research trial. Subject administered 15 mg at 10 am, another 15 at 10 pm before bed. Muscles size up and super hard. Helped subject break numerous plateaus in lifts and overall strength. Skin looks better. More alert. Even vision is improved. Also subject sleeping better, but could be partially due to going heavier and harder during workouts. Only downside is subject’s appetite went way up. It makes some sense due to feeling better, lifting harder, expending more calories! Subject had to start drinking tons of water and have veges on hand to snack on every few hours to stay out of trouble. Compared a number of sites and the value on Sarmtech’s products really can’t be beat.
Mjjc5291 (verified owner) –
Test subject showed increase in sleep quality, muscle mass, decrease in body fat, increase in appetite and over all well being. Highly recommend this product to research the effects of a g.h stimulator. Sarmtech.net with another quality product.

Seems like the real deal, although was the first time I’ve researched with it. From what I’ve been reading, subjects really are not supposed to gain weight short term except water weight? I dunno, my subject gets DEEP sleep, body feels great, a sense of well being, tingling a tiny bit in hands. Subject started mk677 on last week of lgd cycle and it’s been 3 weeks with no loss of weight since. Little more vascular too. Good stuff!
Steven (verified owner) –
Subject gained a lot of weight from using this product. About 7 lbs in 4 weeks. Also stronger. Stacked with S4. Enjoying results for the most part!

Fast awesome shipping, Great gains, Great price. Stacked rad140 (15mg), mk677 (15mg), LGD4033 (10mg) and MK2866 (15mg) and very pleased with experiment results so far! Only 2 weeks in and subject is breaking major records. Will start S4 in week 5 @ (25mg twice daily) and up rad140 dose to (30mg). Will definitely do a PCT along with GW501516.

Hey guys, my subject felt a slight difference and a little bit of a better pump when stacked with mk677 but nothing major and am a little dissappointed because it seem all the other people have such great reccomendations for these two sarms… idk if im doing it wrong because of all the other highly recommended reviews but i dont know. I was expecting alot more of a difference, on my 5th week now and waiting to see if my subject will hit a spurt of something… I read on a sarms website that 10-20mg a day of each is the norm so i stacked one of each daily with breakfast. if anyone has a better regiment please comment on this review. The company as a whole was good though, fast shipping, a definite good service. Thanks alot

This the real deal!! First night subject took, he became extremely hungry and ate everything in the refrigerator. I added this in the later half of an ostarine study which quickly added another 8 lbs to subject after already gaining 11 lbs. I lowered dosage from 30 mg to 15 mg a day since it was slowing subject down a bit. This stuff is very potent to say the least!

Subject showed immediate increase in water weight, hunger, numb hands and all other typical sides and benefits from true MK. I was experimenting with another brand and this one exceeds in quality, I believe. It will take months for subject to really reap the benefits but I believe this to be the best one I have experienced.

Days 5-10 still noticing no difference at 15 mg doses
Days 10-15 starting to see difference in recovery time as well as strength, 15 mg
Days 15-30 clearly noticing differences and recovery time, strength and endurance, 30 mg
Note, subject takes two capsules daily, one early evening and one late evening.
At times feels hungry but that was not an issue.

Subject is a combat vet who suffers from PTSD and cant get more than a few hours of sleep at a time. Subject used mk677 to get better quality sleep. With 45 mgs a day which is the max subject willing to take since the falloff for healing stops roughly around 15 mgs. Research stack with rad 140 and subject started gaining muscle too.
Daniel P. (verified owner) –
High quality sarm, wouldn’t buy from anywhere else.
Andrew M. (verified owner) –
Great product for recovery, especially from injuries. Very high sleep quality increase as well
Michael (verified owner) –
The test subject took the 15mg dose shortly before bed. Within an hour after taking it, subject felt a gentle series of GH pulsations from the pituitary gland, pleasant and unexpected. Subject had a fine night’s sleep, no longer (6 hours a night is standard) but deeper, better (no dreams yet, stay tuned). MK-677 seems to work synergistically with LGD, the combination has yielded incredible results: growing size and muscle density, increased vascularity, more energy, appetite off the charts, and fewer muscular aches. He’s concerned with an increase in blood pressure apparently attributable to MK 677; BP went up 20 points over the first six weeks of an 8-week cycle. Also heard and read about MK’s role in elevating blood glucose. Any advice on whether either of those side effects can be addressed? Discontinuing it for now; I want more info about the side effects, but MK is so strong (especially stacked with LGD) it feels like it’s not necessary to take it every day anyway. All in all, a product that performs as advertised, delivered quickly and priced very competitively. Thanks

By the third week subject started to see an increase in strength and size. The only noticable side effect is a shortness of breath and shallow breathing but that could be the test booster. Increased testosterone thickens the blood.

The mk-677 is one of the best for appetite and size building. Sarmtech has fast shipping and a great rewards program. I am very satisfied with their products and will continue buying from them. The only side effects subject experienced were some really weird dreams I guess because he is sleeping so deep.

Week 3 on this product and my subject reports positively with their results so far. The packaging is appealing and clean. Appreciate an encapsulated product; easy to take and no bad taste. Too early to report on any noticeable gains other then taking 3 weeks off and maintaining strength. Lastly, subject reports deep sleep and restfulness on this product.
