Longevity
Been taking since November and so far feel good, did notice the smell and taste this last order had a huge lemon balm revamp. I like that much better than the old sulfur smell!. I would love to find out more feedback from other Longevity users. I want to learn about my body's processes and how this is helping me achieve my biohacking and Longevity goals . I would loooove to try the Fiber+ next and would appreciate a sample if possible! I currently have a subscription to Longevity, creatine, collagen, vital proteins, omegas. Thanks! Adriana Henry,
