Description

First Endurance OptygenFirst Endurance Optygen is a supplement that uses adaptogens to help the body deal with stress and increase oxygen utilization. Adaptogens are naturally occurring substances that normalize your body's processes during times of stress and exertion. They can help your immune response, aid absorption of nutrients, as well as increase stamina and strength. Optygen uses two of the main adaptogens used by Tibetan Sherpas to help them Climb Mount Everest.

They can help your immune response, aid absorption of nutrients, as well as increase stamina and strength.

Optygen uses two of the main adaptogens used by Tibetan Sherpas to help them Climb Mount Everest. Over time, use of optygen can help increase endurance performance, regulate cortisol levels and reduce lactic acid. While the end goal is to train harder and perform better, it is important to note that to see the effects of Optygen it should be used consistently for many months. Taking Optygen just a few days before a big event will result in very minimal gains.

Busy bone
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves these!! Great busy bone! And they can hold it with her paws really well. It does kill your foot if you step on it barefoot in the middle of the night. This is a picture of the bone after 7months.

My Dog Loves this!
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves her Nubbies! My Dog chews her Nubbie every morning after she has her breakfast. She sometimes wants my husband or I to hold it for her while she chews on it. I think it is really good for her teeth and gums. These last a few months for our dog who chews it every morning. After a few months the edges get a little rough from all the chewing so I throw it out and replace with a new one. These are very reasonably priced, so I always have a fresh one ready to go. She gets very excited when we get a new one out of the package..

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

Great toy to relieve stress in a dog.
Color: Orange
He actually cares FOR this toy. I think he thinks its alive. I put it in his Kong weeble wobble thing because that thing actually is indestructible, thinking he'd be able to play with it but not be able to tear it up and he started yelping like he was hurt. I do expect him at some point to tear this thing up if he gets bored with it. He's a shredder and the material looks shred-able. But right now he loves this thing. First toy he takes to bed with him. ;)
