From what I've seen, black tops that people purchase from ASF have had a good track record.
Every generic HGH company may even get a bad batch. It happened to IL 1 TIME out of about 15ish blood work panels I saw. This company is a "go-to" without a doubt, but still had a hiccup. It just happens. That's another reason blood work is so important.
Most importantly, they made it right. That's all a company can do and that shows the quality of the people behind the scenes.
Read and research and you'll be able to make a educated decision.
There "MAY" even be a thread here at Meso with top 5 HGH by a well respected member names @mands . I'm not sure though.....
