recommendations on the dosage of HGH and my source ?

[Bremyn]

I'm 16 and 11 months , turning 17 next month and I've grown 6 cm since October last year. So I'm thinking I don't necessarily need to get a bone age X ray to ensure my gps are open as I've grown quite a lot, I've also found it quite difficult to get a bone age X ray reference in the UK. I'm going to use 15 IUs of HGH per day using the formula 0.07mg/kg of body weight. Does anyone have any better recommendations or feedback ? I'm also using a source on telegram called Official TFC and was wondering if anyone else has previous experiences with them and can vouch for them.
