I use this for the first time in 2022 after having a big detox blowout in December of 2021 and getting COVID at the beginning of 2022 on top of it. Even after my body felt like it was on its way to healing, I could not get rid of the achy ill feeling. Once starting TB4-FRAG, The body aches went away within days, and it definitely seemed to exponentially speed my recovery. I've had another bout of lingering illness lately, so started it again, and within about 5 days use, the body aches were completely gone for the first time in over 2 months! I love this product for healing and immune support!
