Questions

Good to know

How much weight can I expect to lose?
Everyone is different, but typically clients lose 6 to 10 kg on the 26 day course and 10 to 15 kg on the 40 day course. Clients who add the Ultimate Kit supplements often report a little more.
What does a typical eating day look like?
In the morning you weigh in, take your drops and have fruit with a coffee or tea. Lunch is 100g of lean protein with vegetables, or an approved shake. Dinner is the same as lunch, with the protein of your choice. Through the day you have two fruit and two starch snacks (corn thins work well) and 2 to 3 litres of water. It is all everyday supermarket food, and the guide plans it for you.
The Course or the Ultimate Kit?
The Course is the HC-SLIM drops with the full eating guide and recipes. The Ultimate Kit adds Power Slim and Appetite Control capsules and a bag of shake, for a little extra support.
How do I take the drops?
Eight drops under your tongue, three times a day: morning, lunchtime and around dinner. Hold them for a minute or two before swallowing. The guide covers everything else.
How quickly will it arrive?
We send from Auckland, usually within 1 to 3 working days. Delivery is $8.95 for a course and $11.95 for a kit, once per order.
Can I pay with Afterpay?
Yes. Pay by card, Apple Pay, Google Pay or Afterpay.
Is it right for me?
