So far so good. my rat is on week 2 of my first bottle. My rat began noticing effects around day 5. The rat has been eating at a deficit and continues to notice strength gains and is looking jacked. Extremely quick shipping for an APO address. Highly recommend this company

MK-2866 other known as Ostarine is the one Sarm I always run to when running a cycle. The fullness, hardness and strength that my rat gets is amazing because he sees a noticeable difference within the first week of application. MY rat loves to combine this with GW and MK-677. You will absolutely love this Sarm and any other you choose from Rats Army!
Marquise (verified owner) –
The best to say the least ! my rat not only gained muscle but shed some fat. He did a 2 month cycle, and i can’t wait to start the next one.
Domenic Pardon (verified owner) –
This is good stuff. Recovery is great, better pumps, no joint issues, most of my rat’s lifts went up, overall just feel better. would recommend for research for sure
cubanpie4sho (verified owner) –
So far so good starting week 2 already starting to notice that my rat has more energy and a bit of strength at the gym this stuff definitely works totally recommend.
Jon –
My rat used 3x now. Noticeable body recomp effect gets better and better each time. no supression and he is feeling good even post cycle. nice addition or standalone to a current stack!
Jim (verified owner) –
I received this in the mail a little over a week ago. It was really nice to have Ostarine again! My pharmacy would no longer carry it and it was a huge disappointment, as this compound really helps with my rat’s joint pain. After almost 30 years of training, the old joints need some help. Lol! The smell was better than expected but still something to get used to. I will definitely be ordering more!
Jayson Walter –
Quality products, decent shipping time

Jordan Vincent (verified owner) –
Real legit stuff! Only did a short 4 week cycle and increased all my rat’s compound lifts by 20kg, will definitely be ordering a lot more!

Ordered many products from this company this was one of them. They all worked and are great but they never payed the postage. So I had to pay out of my own pocket and caused it to be 4 days late. Hesitant to order again.

This stuff is great, my rat seems to be enjoying clown tears flavor. I’ve seen nice gains and endurance in my rat. This company is one of the best legit companies in the market. With easy payment method and proper packaging for shipping.! This is my go to for all sarms.

Great beginner research if your on sure of the whole “rat research” Mild to no side effects and very great cutting agent. Also my rats neck was hurting pretty bad from benching, this healed it right up after a week or so.

Chris Williams –
I can’t say products are bad because they did what they were supposed to but they literally made my rat sick, like throw up sick. My rat stopped using after only one bottle and switched to another brand and my rat felt fine. Now, I want to be very clear here I’m not knocking RA or saying anything negative about the product, could’ve just been my rat’s bodily reaction. I will say my rat used other products from reputable sources in the past and have seen results so I know they were real and never got/felt sick. I just chalked it up to must be the smell that my body/stomach doesn’t like, all other aspects were there would be 5 stars other than my rat felt like $hit on them.

Jonathan Sanders (verified owner) –
My rat in the first month shed some body fat and packed on at least a lb or more of solid muscle tissue. Its lower body push strength went up a whopping 30 percent on max effort lower body activation. I’ll be running another 4 week cycle to see how the rat performs in cardiovascular exercise and speed. Great product
amullins613 (verified owner) –
I love this stuff, it’s harsh yes but 1000% worth it. The Maui Maui flavor is my rats favorite. Sour apple is ROUGH she did not like it
I’m a 29 year old mother of 2 and My rat lost a good amount of fat & inches. It also increased its strength substantially. I highly recommend. I only order from this site because I know this stuff is legit just by my rats results!
judahisraelmichael (verified owner) –
Ostarine is the real deal. It helped my rat gain 5% body weight (of mostly muscle) within eight weeks. He got stronger the whole time, and definitely manage to lean out despite the fact that his weight went up.
I really enjoyed ordering from Rats Army as they have a great online reputation, good customer service, and their products’ quality and effectiveness speak for itself.
Andrew Cate (verified owner) –
I took a low dose 8 week cycle. My body fat went from %16 to %13. I could definitely tell that I gained lean muscle and my body weight stayed the same, this is a very god product for recomp. I highly recommend.
Aaron G (verified owner) –
Decided to run a SARM cycle for my rat and Ostarine seems like a great introduction. Energy is up, crushing workouts, and visibly losing body fat quickly. Can’t thank Rats Army enough!
Charles Graham (verified owner) –
Wonderful service – quick – easy – great for research – will order again
Jerry Gonzalez (verified owner) –
My rat saw results within the first week of using it. This stuff is insane, definitely recommend!
Rat’s Army is the Go-to for my research! (verified owner) –
Rat’s army is my go to for all of my SARMS! This is my second cycle from them and I am pleasantly pleased with how pure their products are! I cannot believe any of the competition and their claims because rat’s army is the best! Ostarine has helped improve my vascularity and I have even gained muscle mass while toning!
The deals add icing to the cake for an already great company!
Thanks!

Noticeable Increase in muscle size, strength gains are absolutely legit!!! Flavor is amazing, tastes exactly as named, like candy!

I ordered this Rad 140, Adex (no longer carried), clomid, nolvadex and tadalafil. Ive tried all of these research chems except the clomid and nolvadex so far. Every ingredient listed is what you are getting. Their tadalafil had me hard as a rock with half a ml! The Anastrazole/adex was one of the most potent Ive ever tried as at .5mg I was getting night sweats… had to do .5mg EOD instead of competitors 1mg a day! The Rad140 and Ostarine work fantastic but IMO drugs work better then SARMS so I just do the real deal as it is most cost effective but if you want to get big “legally” use these SARMS. Ive ordered 4 times from here and once I had an issue with shipping and Tyler rectified it. He is the owner, and he didnt know at the time but I lost my package, and I have friends who know him personally , and he rectified the situation immediately without me having to name drop. KUDOS to Tyler, his company and his high grade/purity products!
