I am sure that 10-15 years ago there was tons of fake D-bol was on the market. I had several suppliers legitimately tested. Most of those pink Anabol tabs going around were fakes... some were Halo, some were inert. Halo might be expensive now (news to me), but not back then.
Who knows what is out there now... things only get worse, not better. It's been 15 years since I dabbled with gear. Unless you are having the stuff tested by a reputable, legitimate lab, there is really NO WAY to know what it is. -
I think you are thinking of methyltestosterone, not Halo. Methyltest was sometimes substituted for dbol.
I also used Thai Anabol over many years. They were always amazing for me, though I read fakes were around.
Today there are tons of legit drugs around. The internet has policed the market a lot, word gets around immediately, and no supplier who wants to stay in business wants to sell inert shit. Makes no sense especially since legit powders are plentiful. Not to say there are no problems.
Totally inert shit I saw in the 90's, not so much now. Actually Halo is the only drug I suspect has been fake for me a couple of times.
