Biosignature is NOT a scam and most who think it is are too dumb/lazy to learn and understand the concept fully. It is a great TOOL to use with clients but like with everything it anyone can do a coarse or study and become qualified in whatever, BUT may not have a clue as to how to use the information.
Looking at your Bio Signature BRIEFLY I would say that you
1. have issues with cortisol/insulin see saw meaning unstable blood sugar and maybe not enough frequent meals?
2. Have issue eliminating estrogen hence the high hamstring folds which are also leading to aromatisation(high pec)
3. Low testosterone hence high tricep.
4. You MAY have some toxicity...well everyone will, but you might have more than most.
5. Your liver health may not be optimal.
Not sure why he drew such a short conclusion, but GH is not an issue compared to the rest IMHO.
This is not in any particular order btw,
PM me if you want some info, but it would be unfair to give you any more info for free.
