You must EXPLAIN to him why this is a BAD business. Remember don't just say bad words about them(like our TS here) without explaination, facts and logic. There are trained to tell their prospects later like..,..."You see, many people talk bad about us because they are jealous of others success" or "Those are our ex-members, they failed because they never follow our instructions and now they are jealous"....Such words they used have been every effective in their sponsoring.
That's why some people say Steven Yeam actually PAID the TS to start this thread in order, so that they can make use of it to promote better.......Last time I saw some better threads and some blogs with good info on explaining why LB is bad, but I lost them. Maybe some kind people can put the link back.
Briefly, you can tell your friend:(also tell him that he will not know or hear all these below because they are all covered; remember LB members are all well trained).
a) Now is more difficult to do this business as most people are already against them, that's why in Malaysia, mostly active now are Malays.
b) The product is 100 over years but don't forget their pricings in US and Europe are only 20% to 25% of the Malaysian price and considering purchasing power and stand living there is 3 times richer than Malaysia, that makes the price here IMPOSSIBLE to sell. Which means.........
c) Your friend must recruit many VICTIMS like him to pay such money in order for your friend to make back his capital. Tell him he will be losing alot of friends eventually. Don't victimise your own friends.
d) I think this is most IMPORTANT. Lampe Berger in US and Europe is sold as a fragrance but the MLM here sell them as Aromatherapy products. Real aroma products MUST be pure essential oils and cost even much cheaper and yet better. Lampe Berger members will deny this fact but you can surf the official website of Lampe Berger or any US online site.
e) Those products are very troublesome to use. Everytime you must on the fire and you must OFF the fire when you wish to stop and the oils are very costly. Real aroma oils or even any branded perfume smell better.
f) They are promised money back guarantee if they wish to quit the business but most people cannot get most of their money back due to "conditions" hidden here and there.
g) He will tell you he go for the other products like Cosmetics instead. Tell him it is crazy to stock up 30K worth of cosmetics.
I think the 5 facts above are good enough to prevent your friend from being victimised. If he still join, he must be a real FOOL and you can try this last trick.....I tried it on my friend and it worked...Tell him:
"After I gave you all the facts and advise and if you still choose such a SCAM business to victimise others, I don't want you as a friend, PLEASE don't ever contact me again if you join them" but please make sure you explain all the above first, you can remember them all ?? Print this out and carry it along with you.

hey fren! I didn't received any payment from Steven Yeam and in fact,.....Im not a Lampe Berger/ SYN mamber too.I didnt join this MLM after been approach by my fren!
Every SCAMs have agreements that protect the Company. It's their training and stragedy that is strong. They PAID the TS to start this "hatred" thread so that they can use it to psycho their prospects.
Again! since when Im paid to start tis thread? is those Lampa ppl dun admit their image has been polluted!
