    I am very impressed with the Ostarine, Testolone, and Ibutamoren portions of this stack. The Test Booster is nice and helped with PCT. I was not impressed with the NO2 Pump as I get better results from my existing pre-workout supplement.

    This stack is insane. Subject got ridiculously strong. Subject gained lots of muscle while burning fat. Subject’s lifts went up and the subject most definitely saw major results.

    My experiment was with the Rad140 Stack. In the first few weeks of the cycle my lab [subject] experienced noticeable gains in strength and muscle mass which was great!! To try and help keep some of the body fat to a minimum cardarine was added to the cycle in week 3 for the remainder of the cycle also with noticeable change in body composition. During the cycle there was no change in appetite no enhanced hunger this may be because my lab [subject] became bloated and constipated and not sure the reason for this but insomnia was also a problem. As we proceeded into week 6 my subject suffered a shoulder injury and had to take it easy for a couple weeks. Weeks 8 thru 12 my lab [subject] was working hard as possible to try and keep the gains that were achieved early on but that was literally impossible without the appetite and proper rest.Most of the strength gains remained to week 12 but not the mass gains. I believe without all the complications that the outcome would have been different so we decided to hold another experiment after the pct except we are going to build our own stack and see how that goes I took my [subject] for labs immediately after cycle and this stuff is very suppressive. I didnt want to review this because of the issues we had but from what I noticed in my experiment in the beginning “Pros” Early Strength and Mass Gains “Cons” Bloating,Constipation,Insomnia that is why Im giving this first review 3 Stars until my next experiment Im already ordering.

    Nearly 2 weeks in and not much. I’m 5’11 200. Feel not much of anything from the RAD Stack. The Nitric oxide booster is legitimate though, not sure if I got a bad batch or what; but pretty disappointed

    After finishing a bulking rad-140 the test subject has just started this cutting stack and it already has shown signs of progress in just a few days! Another Highly recommended product from sarmtech! 5 stars!

    LGD stack for 8 weeks. Test subject had a skin rash issue that could have been an external source on palm of hand. Really nasty looking. You need to drink lots of water, like 2+ gallons a day to combat dry cracked lips and especially at the corners of mouth. Removed the MK2866 & NO2 from stack for 1 week and it went away. Even with that, I would say test subject experienced great results. Probably 10lb of muscle -5% body fat. Lost 8lb total but don’t know body fat % at start. Noticeable changes visually. Went from a small gut to 6 pack, shredded shoulders, vascular arms starting to pop. Strict diet and lifting routine maintained. Would & have recommended to others. (40yrs old, male, 6ft, 210lb start 202lb at end) Overall mood was elevated too throughout 8 weeks.

    The value of the stack is great. I appreciate being able to save money buy purchasing the products together. [Research subject] currently taking the RAD-140 stack with an S-4 added. The results are pretty shocking. [Subject’s] weights have been increasing every week while taking the stack. However, [subject] did start on an de-load week with only lifting half volume. Five weeks in to cycle and the results are great. I highly recommend this product. No side effects noted at all…well, I think the MK-677 makes [subject] really hungry. Also, the water retention is significant. Been cutting back on calories every week and weight has remained stable. Typically with the calorie intake on now, [subject] would have lost 3-4 pounds by now. Perhaps it’s muscle and not water retention, but there’s no way to know for sure until off the stack. Also taking the NO2 prior to working out each day. 2 pills did nothing, but 3 seem to have a nice pump effect. As far as other dosages, [subject] taking one of each every morning after breakfast, about an hour and a half before the gym.

    Taking the LGD-4 Stack and am impressed thus far. Getting results even with my test subjects workouts not being as consistent as they should be. I would give this product a 5 out of 5 but would like to see product come in various mg Totals. For instance, I want to take 20 to 25mg of LGD-4 but because it only comes in 15mg capsules that makes it hard. That’s really my only complaint, otherwise, product is well priced, yields results, and shipping/customer service has been outstanding.

    First off, the shipping is insanely fast. My subject is currently overseas and most packages take a month to get. The subjects order arrived in eleven days from the date of order. Most definitely an A+ for shipping. The subject just recently started researching but has experience from past research. The LGD was felt within the first few hours of a 10mg dose, nothing insane, just noticeably fuller feeling muscles and a little bit more endurance. After a week of dosing MK2866(15mg daily) the subject began noticing a positive change with a herniated disc in his back along with decreased swelling of the area. The first night of dosing the subject with 15mg Mk677, the subjects sleep was much deeper and hunger has skyrocketed. So far, the subject is extremely pleased with the short term benifits that he is receiving and is excited to continue his research.
