Tesamorelin — approximately 4.5 to 6.0 Tesamorelin is a 44 amino acid GHRH analog — meaning it mimics the hormone that signals the pituitary to release growth hormone. Its solutions typically land in the 4.5 to 6.0 range. At the higher end of that window it begins approaching a more tolerable distance from tissue pH, which is why

Both are accurate. Your RS’s baseline tissue pH isn’t a fixed number. It sits in the 7.0 to 7.4 range on average, but it shifts based on factors that are easy to overlook. Hydration is one of the biggest — well-hydrated tissue maintains a more stable pH environment, while dehydration concentrates the surrounding
