Annika and Tristan have gone ABOVE AND BEYOND for my husband who is getting off of TRT!!! They have treated us like family and working with them has been such an enjoyable and rewarding experience. They have been extremely communicative and supportive every step of the way and have seriously been such a blessing throughout this journey. I will only recommend Annika and Tristan to anyone who is looking into hormone therapy, getting on or off of it. Their knowledge and understanding of hormones greatly surpasses that of any other hormone specialist we’ve worked with. Thank you!!

I have been working with this team for the past 8 months, I am in my mid 50's and was low on energy, not sleeping well and wanted to lose weight. I started testosterone for the first 6 months, and this helped with energy and sleeping better and even improved my moods. In the past 2 months, I started Tirzepatide and lost 15 lbs. This has helped me decrease the amount of food that I eat and made me feel better and increased my energy.
The team is always available to answer questions and give me advice but let's me make the decision on the steps I want to take.

I was skeptical at first, but contacting Activ8 was one of the best decisions I have made. I started my Tirzepatide journey in Mid-October on a smaller dose and have lost 10 steadily! Aside from changes on the scale, I have more energy, less inflammation, and overall feeling more confident in myself. I have only had mild side effects, but have been able to manage as the weeks go on. I am extremely happy with the results so far, and excited to continue!

I have always been an extremely active person but when I reached my late 50s into 60s I could tell I was slowing down and lacked energy to do the things I loved. After talking with a good friend about testosterone injections I decided to seek out help. Anika and Tina Lisa were the gals I turned to for help. They put me on testosterone therapy and it has completely improved my life. I now have energy to do all the things I enjoy in life. No side effects, no issues, no worries, just happiness. 😀

As a recently retired father and grandfather, staying active has always been central to my life. But after cancer surgery and gradual weight gain, even my regular cycling and cross-country skiing weren’t enough to bring my weight down. Diets didn’t help, and my energy was fading.

When I decided to try Tirzepatide, my wife and I set the goal of reducing our BMIs below 25. To my amazement, I reached that goal in only 26 days. The injections were simple, comfortable, and easy to administer, and the only side effect I experienced was mild occasional heartburn, which resolved quickly.

Over time, I lost 13 kg (28.3 lbs) in total and returned to a BMI of 24. My workouts felt easier, skiing became effortless, and I regained the vitality I thought I had lost for good. With maintenance dosing, keeping the weight off has been straightforward.

Tirzepatide has been a fast, safe, and truly life-changing solution for me, and I am deeply grateful for the renewed health and confidence it brought back into my life.

After 2 doctors rolling their eyes at my 219 testosterone level, Activ8 saw me the SAME DAY that I set up the appointment, set up treatment immediately, and was very receptive / sympathetic to my problems associated with low testosterone levels. Highly recommend.

After only 8 weeks on Phentermine, I have lost 21 pounds! My goal is to lose 25 pounds, so I am very close to it in a short period of time. Along with exercise and a careful diet plan, this was a very easy experience and I recommend it to Menopausal women who struggle with sensible weight loss. The support and counseling from Annika and Tiinaliisa have been priceless!

Wow. I started my weight loss journey and my hormones therapy journey. In a week and half, I’ve lost 10pounds. I know it sounds unbelievable but it’s my story and it’s the truth. This is not a bot, this is a real person. Hormonal Journey has been amazing as well. I am sleeping like no one’s business. I can’t stop sleeping. I feel so relaxed and full of energy and happy. And lastly, the doctors are amazing, feels like I am speaking with my sisters whenever I call them lol. Ladies, the best gift we can give ourselves is to take care of ourselves, it’s never too late to check your hormones to know what exactly is going on with your body.

I can't say enough about Activ8 Health in Phoenix! After thinking I had no hope of feeling better, I found them and they actually listened instead of just writing a prescription or telling me "this is normal". Thanks a million to Activ8 Health!

I am a a 60-year-old woman who was struggling with my energy and libido for many years. I had tried pellet therapy in the past, but had so much scar tissue in my buttock that was very painful and uncomfortable. I met Annika and she showed me the way with testosterone injections. It was an absolute game changer. I do one shot once a week. I have restored my youthful energy, my libido, and I am enjoying a wonderful relationship intimately with my husband like never before. The second half of life can be as vibrant as the first ! Thank you Annika. You guys are the best.
