It can’t hurt to start there. There’s every chance Tesa would bring you to the very high end of physiological IGF range, something those using ~4iu rHGH are lucky to achieve, many needing more, with fewer sides and no diabetogenic concerns or dealing with timing of dose or food (makes no difference because of how it works, unlike rHGH). And it’s arguably the safest way to get a big boost in GH/IGF.
I don’t see your age, but I’ve you’re over 30, retaining the natural pulsation of GH release (a few minutes at a time) is much more effective than rHGH at getting rid of the visceral fat you’ve accumulated,
(No matter your overall body weight, IGF decline post 25yrs redistributes fat into visceral depots), over a 4-6 month 2mg/day Tesa cycle. That will Improve your metabolic health significantly (you’ll see it on lipid and inflammation markers, it’s not subtle).
After maxing out the visceral fat reduction, you can decide if you want to “graduate” to rHGH, for stronger anabolic and general anti aging effects, at the cost of more careful management (timing, food, blood glucose monitoring), increased sides, and higher risk.
As a bonus, the visceral fat loss will increase GH to IGF conversion efficiency, so in a sense the Tesa will “prep” your body for rHGH, allowing a lower, safer, less side effect inducing rHGH dose to give you a higher more anabolic muscle building IGF level.
