a friend (well friend of a friend) tried to get me on to a competitor product.
that too was a multilevel marketing sales method, and also kept getting legal threats for being a pyramid scheme, but always kept winning, since there is a product (and is legal and highly regulated). a pyramid scheme is merely a scheme to make money flow with no product (and is illegal).
my experience was that the product was a bit more than a placebo, and to make the MLM network marketing bit work… was expensive and needing regular repeat orders.
effectively lost a few friends because of the sell sell sell of the product, and virtually a cult in trying to coerce others into becoming downline sellers.
no idea about the herbalife product itself though.
