Awhile back someone gave me a few packets of some 17-HD from Vyotech Nutritionals. Is this supplement a steroid like supplement or just junk?

What does 17-HD contain

It contains a few herbal supplements(junk), but the main active ingredient behind the supplement is what they call 17-halo methyl-dianadrone. At first look of the name of the compount, it gives the impression of a halo based steroid, like halotestin or halodrol.

Is it a steroid/pro-hormone?

Despite the name of the compound, they market the product as a testosterone booster. To find out if this supplement works you would have to find out more about dianadrone. There is no results for dianadrone, methyl-dianadrone, or halo-methyl dianadrone in pubmed as far as studies. I couldn’t find any any information about this compound with real research studies, anywhere else either. It is nothing, but a fake name branded by this company. I wouldn’t trust the studies Vyotech did, as obviously they will be biased. 17-HD looks like nothing but a junk supplement, full of unproven herbs.

What do other bodybuilders report?

Except for a few who probably report placebo gains, the vast majority notice nothing.
