Great customer service and even better products.

Love the shirt and all of the products from savage! If you aren't taking savage supplements you aren't at the top of your game. Simple as that.

First thing I noticed was the size of the scoop, you just know your getting the right doses with no wasted ingredients. I liked this was not a blend and every ingredient was listed out on the back of the container. The claim of this product is strength, endurance, focus and massive pump. I would have to agree to all these claims. Strength, endurance was good and carried me through my most brutal of leg days. The pump lasted for hours and could still feel it even after a long day. Only thing I didn't like was that the energy didn't last for me. So I would rank this pre-workout a 5 out of the 65 pre-workouts that I have had or have tried.

I love it!!! This supplement is amazing!!!:) I definitely will be purchasing more when I run out and I definitely would highly recommend this product to anyone.

My body doesn't build up tolerance to this. I usually take half a scoop and I weigh 120 lbs. the first time I took it I was in the gym for 2 hours and still felt like I could do more. Best preworkout I've tried thus far.

I got both products, Medusa and Siren, and they are hands down amazing. I've only been using them both for about a week now and I can already see a transformation. I highly recommend these porducts!

Good Product and quick shippinng! Will shop again!

This preworkout is amazing! I took it at 8am and by noon I had already worked out, washed the dogs, painted the house, and ran a marathon! Well, not really but I could've done all those things with the amount of energy and focus I had. Will definitely buy more in the future.

Siren made me a beast in the gym!

I love this brand! The products are top notch and this pre workout is one of the best I've used. Doesn't make you feel too jittery either! a must try!

This is exactly what I was looking for, great energy and focus. The pump was a huge bonus. Thanks!

SIREN is loaded with 1,3 Dimethylamylamine which is AWESOME (for noobs thats a neural stimulant with a structure similar to Ephedrine and adrenaline) BUT it doesn't give CRAZY jitters and crashes to my body!!! Absolutely effective....No chemical flavoring and it's quite smooth and great tasting - I HATE SWEET preworkouts and Bcaa's more than anything! Can't wait to test out their new fat burner soon!

Keeps me on my toes! Great product!

Siren has been helping me get through my two-a-days. 5 AM wake up calls for a night owl are not a lot of fun, but once I get out of bed and take Siren I am up, I'm pumped to get to the gym, and I am very focused to kill my workouts!

I'm going to say it. This is the best product I've taken since the original DS craze. Taste is awesome, packed with great ingredients, and not under dosed like a large quantity of pres on the market. If you are new to supplements, or very stim sensitive I would recommend starting at a lower level pre workout, or only taking 1/4th of a scoop at first. This stuff is no joke and a great example of what pre workouts use to be like before the dmaa fiasco. This will be one of those products I always have on hand, and I really look forward to seeing what savage can put out next. You will NOT be disappointed in this product. Only complaint is, I would give the mixability 4/5 stars. I had some clumps at the bottom of my cup but very minimal and it's a very small price to pay for such a perfect product!!

Siren is hands down the best pre workout available today! Super clean focus and energy! The pump it gives you is insane! I have to take a break during leg day because the pump was so strong! If your on the fence give this a try you won't be disappointed!

I've used DMAA-powered preworkouts extensively in the past, and SIREN stands out as the only one that gives me a controlled, focused mental drive on top of the energy rush. It's led to both more productive and faster lifting sessions, and makes fasted cardio an absolute breeze. Looking forward to some new flavor releases!

Great product, great ingredients, great pump. This was just what I was looking for in a pre workout. I don't feel jittery or itchy during or after either. Will be coming back again. Thanks a bunch!

Siren pre workout is one of a kind. When many products on the market use gimmick ingredients and unnecessary dosages, Siren pre work made by Savage supplements uses scientifically proven ingredients and dosages to create a one of a kind product. Siren provided me with the necessary ingredients to push my workouts to the next level. My energy and stamina increased as well as my strength. If you are looking for a quality tested product that has no gimmick ingredients, then Siren must be your choice. Be ready to take your workouts to a whole nother level!

This pre work out is off the charts. First time taking it I took the recommended dose and couldn't stop lifting. The pump is in incredible. This is truely for savages that want the best performance out of a pre work out. No uncomfortable tingling. Great focus and energy! Can't wait for the next product!
