AMH or enyouth used dr lazar as their marketing tool. he is a so called scientific advisor inside, but that's all. he is only responsible for authorizing ALA, but a lot of people are tricked into thinking he advocates mattresses too.
CosLab is started by Dr Andrew ler, also a scientific advisor. my advice is - dun be in such a hurry to invest just cos you see a couple of PHDs. having phds doesn't make you an expert in MLM. my friend just lost 2k in it, and she lamented that the products aren't half as good as they claim. that's the irony - you use, cannot refund. dun use, how to know if it's good?
