    Test subject took the Rad 140 stack for 90 days. In that time subject gained 24 lbs of mass and added 45lbs to bench press. Going from 305-350. The pumps received during the cycle were described as strong and full. Strength gains were noticeable in all movements. User gained mass on entire body. Subject would use again for sure. Great product for test subjects looking to gain size and strength.

    Good value on the products and incredibly fast shipping. Only down side is the half-life of Stenabolic is 4 hours so you need to break over the capsule and break up the dose throughout the day. Easy of coarse, but would be better with more capsules in smaller dosages. Ultimately been happy with the products I’ve ordered over the last year.

    the Rad-140 is the best stack. I’ve used it 2 separate times and worked like magic both cycles.

    Stacks are great. Save money and you can add the one or two extras on the side.

    Great stack! Subject is almost finished with first cycle and the weights in every muscle group have increased along with size. Subject has added about 2-3 pounds of muscle on this cycle doing a single dose. Going to continue the stack for another cycle, doubling the dosage to see more gains. Great product, zero side affects!

    Very happy with this product. [Subject] had some good gains on it and recovery was great. Was holding a steady 180-185 LBS before and now holding around 195-203 LBS. Will order this again in the future and this product had no bad side affects for [my subject].

    Got the Ostarine stack. It Works Great and it’s a very good combination. Massive strength and size gains.

    Michal Malyszko (verified owner)

    So far so good. Test subject began at 285 units of weight, got down to 235 just through regular training over the course of a year. Addition of Cardarine saw a further decrease from 235 to 180 within 4 months, with some decrease in muscle mass but nowhere near the decrease that incurred without it. Body recomposition more favorable with the product, test subject appears to have lost significantly more weight units from fat storage rather than through muscle storage. Once desired composition is achieved, will use remainder of stack (ostarine, mk, nitro booster) in order to engage further recomp to build additional muscle. Once that stage of the lab trial begins, will update review to advise of efficacy of that portion of the stack. The efficacy of the Cardarine alone made the cost worthwhile, if the ostarine and remaining sarms display any meaningful impact they will be considered a bonus. A note to prospective purchasers and lab technicians: Cardarine alone will not render desired effect without monitoring of calorie intake, engaging in strength training to maintain musculature, and using cardio strategically to supplement the effects of the substance. No amount of cardarine will outweigh an imbalance in the other aspects of a rigorous laboratory test, similarly with any other substance in this stack. The changes you will see are earned, just faster and perhaps more favorably, through the use of these things. However, they will not come if your test subject fails to commit fully to seeing through all parts of the examination. Best of luck to all of you experimental scientists out there, may you see the lab results that you want to see.

    I am 6 weeks into the “maintenance stack” fro Sarmtech. Stack is legit and I am using Ostarine, Cardarine and free up. [Subject’s] Body fat down 4% and weight up 7 lbs. This is the first time I’ve ever [researched with] Sarms and am a newly converted fan! Anybody wanting [their research subject] to get lean while also putting on some muscle should truly look into this stack and give it a try. Everything from Sarmtech is legit!!!

    Good strength and really good muscle gains/hardness/fullness. Subject had mild stomach upset for a few hours in the morning post-admin over the course of this 7 week cycle that I’m pretty sure was the S23. Hve used the others before but not S23. Plowed through it and glad we did for the great results. 5 Stars for Kimberley and SARMTECH team, just minus one for the stomach stuff. Will go back to RAD140 again next time. Cheers!

    Great all around stack. Only recommendation would be adding MK677 to the maintenance stack than overall value doubles in my opinion. Great company, great products, great pricing…no complaints what so ever . Highly recommend

    GW/MK6 Cutting Stack
    Really enjoyed this stack. Hadn’t ran Osta in quite some time and was looking to lean bulk/recomp a bit [for research subject]. Stack worked perfectly for. Ran it at one pill of each on off days and two pills of each on training days, one AM and one pre-workout PM. Noticed really good pumps, increased vascularity, better stamina, and steady strength increase over the cycle. [Subject] Gained 8-10lbs over 10 weeks and leaned up a bit. Writing this review almost a month post cycle and still maintaining weight at 240lbs. I definitely recommend this stack. Very versatile and will for sure be running this again come spring/summer.

    During the science experiment the subject gained almost 50 pounds over two months. Strength and muscle growth is exponential. The people around him began asking for tips or how he did it to achieve the amazing growth. Another subject joined the testing phase as well. Overall will recommend.

    Lab Subject (LS) started with sarmtech in April on their maintenance stack when my gym closed. It helped LS stay energetic and keep gains. Ordered rad140 stack plus an extra creatine in July then started the stack in Aug when LS finally got in home gym equipment. Aug-Oct LS was quite disciplined on the stack and diet (completely cut out all breads and pasta), and daily lifting. At almost 37 LS looks better than at 18 in varsity football. LS feels energetic a/f too. Bi’s, tri’s, quads, back, and shoulders blew up. Mild 4 pack turned into a defined 6 pack. Not all of this is attributable to the sarms but no way LS could’ve got this ripped without. Dosed 1 capsule each per day except creatine doubled the reco dose of 3 to 4 (2 morning, 2 afternoon at workout alongside the nitric oxide). Went back and ordered another 2 bottles creatine at that rate for full 3 mo cycle. So that’s the product, A++. On to the company – the site is well thought out, multiple lab tests for each sarm was impressive, venmo payment was easy. The order shipped the same day and was impressed with the email feedback right away with photos of the shipping progress and tracking link. Arrived in mailbox 2 days later, very well packaged. Awesome silvery labels. Also silvery sticker and business card in the box. It might seem like a small thing how nice the bottles and labels are but just exudes “high-end”. Other sarms I’ve ordered there’s a plain little paper printed label that looks worse than anything I could do in MSWord. It just tells me everything they do is spot on. Like when there’s heavy silverware and a cloth napkin at a restaurant you’re not surprised how good the food turns out to be. I tend to rant out businesses when I get the chance so quid pro quo when there’s a company doing everything right, A++, I’m giving them the same (but opposite) treatment 💪

    User gained 11lbs of muscle, unfortunately bad diet led to an explosive weight jump from 265lbs to 292lbs. NOT the fault of Sarmstech. This stack has increased strength and muscle definition exponentially in the user! Remember to eat clean and well, no fast foods ladies and gentleman.

    Second cycle on ostarine ligangrol stack. This stack with 6 different compounds was twice as much of each product and about 70% of the price of my last supplier (whose package got seized in Customs)!

    4th time with your gear in 2 years. S23 stack this time, Lgd stack last. S23 was amazing might as well have been test. Mk6 and Creatine performed solid. I appreciate the quality in all you do, no cutting corners. Keep it up!

    LGD stack was phenomenal. Started my lab experiment at 2 capsules each but upon further research read LGD can have same results at much lower doses, even 1.5mg/day! So 1 cap/day seemed very logical. So 90 capsules went almost 90 days cycle – agreat value! This was bout half yr ago. On site now to re up. Solid company.

    Johnny Comrade (verified owner)

    Started out with really good results. The subject gained muscle and was able to recover much faster. In total the subject gained 5lbs of muscle. They were on a 4 day split. In the 4th week the subject lost the drive that originally came with the research chemical, how ever this may have been from the increased work load they received. The subject will be trying the research chemical for another cycle.
    Notable sides/ adverse were bloating with gas, insomnia for the first few days which then subsided.

    Lgd 4300 stack results:
    The user went from 174lbs @ 17.4% Body fat to 203lbs at 19.2% Body fat over the course of 8 weeks with a daily calorie intake of 3500-4500. The user drank alcohol 3 separate occasions during the course of training, each time resulting in a drop in weight likely due to dehydration.

    Side effects:
    User noted experiencing waves of strong anxiety and depression.

    Overall experience: 7.5/10

    The gains happen fairly quickly and significantly help increase muscle mass, but the waves of depression drop what would be a 9.5/10 experience to a 7.5.
