This is my first time using Rats Army. Ordered from Oz and it all went amazingly smoothly, choice, flavor, payment and receiving. Product arrived in 10 days. Packaging fantastic and the quality oh so much better than what I have used in the past. One week in and feeling the benefits already. Very happy and thinking about my next purchase 🙂

Works fantastic and doesn’t taste terrible compared to tiger sarms. I got the green apple. Injuries are healing nicely and strength has increased. Will order more.

Phenomenal customer service. Always quick response when you reach out with a question. Products have clean and professional labeling. My research subject loves the Mai Tai flavored MK677!

Jonathan Gonzalez –
Don’t really know if it’s working. But there’s one thing I must say. The costumer service isn’t too good and the order took long to deliver. There was a problem with my order and costumer service was pretty hard to deal with. That was my experience personally.
George Nicoll (verified owner) –
Amazing, such a good product! Would highly recommend!
Lucas –
Effects are amazing! Definitely going to buy again. Highly recommend!

I have used plenty of sarms in the past with multiple different companies, and Rats army BY FAR has the BEST sarms on the market!!! I personally am running MK-677 for about 6 months now and I can say that my recovery has been amazing, lagging injuries do not bother me at all anymore, I am already very lean so the little bit of extra water retention really makes my physique look full and muscles hard as steel. This is a great sarm to run by itself for HGH benefits and well-being as well as a must have in any cycle I use. You will not be disappointed!

My lab rat has been taking mk-677 for about three days now. It has done everything that i was expecting. Great product and i would definitely recommend anyone who is trying to get their lab rat right to get this product!
Trevor (verified owner) –

Benjamin Logan (verified owner) –
Awesome product. Performs as well as competitors at a better price.
conorkeehley (verified owner) –
Plan on running this for at least a few months. If you’re trying to bulk or if you’re just a hard gainer this stuff is awesome for increasing your appetite. Definitely recommend. I love that it doesn’t really affect hormone levels too.
Dan –
Great product. Great customer service. My appetite and sleep are amazing.
jason.bevill (verified owner) –
My recovery was fantastic but I definitely got the swelling in my lower joints over time. Great for pushing your body to the limit, just make sure you’re taking something anti inflammatory!
Paul (verified owner) –
It works and will def make you hungry. The first time taking this I woke up in the middle of the night with hunger pains so bad I was eating anything i could find in the dark. I have trouble gaining weight and having an appetite. I use this for a couple months then take a break then do another 2 months.
Jordan (verified owner) –
Mk677 is legit. Quality product. Received in about 10 days.
truesomnium (verified owner) –
This tastes great, shortly after taking it I felt the hunger kick in, which proves this is in fact legitimate mk-677, looking forward to the results of this fantastic product!
Eric Gillihan (verified owner) –
Legit! I know this because the hunger is unreal! My rat has to split the dose in the am, and in the evening to try and mitigate this effect.

can’t wait to start seeing results
