There seems to be no available research on the product GFrag, only on growth hormone itself, which is what the product has been modelled around – a popular addition to many serious bodybuilders/fitness models’ training programmes.
‘Gh fragment 177-191 is a stabilized analogue of the growth hormone-releasing factor (GRF) that induces Growth Hormone in a specific and physiological manner. To date, studies suggest that HGH Fragment 177-191 has several beneficial features: it reduces abdominal fat in particular visceral fat, without compromising glycemic control (blood glucose), it increases muscle mass and improves the lipid profile’

As a rule, though, I do not recommend or endorse ANY products that present themselves as a solution to weight loss. Nothing can replace regular exercise and clean eating. Whilst growth hormone has been widely used to improve training results, I cannot conclude that this is what is represented by the product ‘GFrag’, nor do I find the research on actual growth hormone conclusive enough to rule out side-effects and recommend it to any body, especially before the fundamentals of exercise and nutrition have been implemented to their maximum.
