Hi - I hope you're still here
The slimgenics plan is very expensive, IMO. They base the amount on how much you have to lose and how long it should take you to lose it. I'd say the average is around $600 -$1000, depending if you buy the bars & supplements.
You can buy their supplements on their website without being a member. And if you knew how many protiens/fruits/veggies/fats you needed you could do the plan on your own.
I buy my bars at the grocery store - I've found some with comparable nutrition facts.
Let me know if I can help you more.
