About Rose Cook
Rose Cook is a New Zealand weight loss company with one focus: helping Kiwis lose weight safely, simply, and for good. Since 2014, we have helped over 30,000 New Zealanders reach their goal weight using the HC-SLIM program — a structured, step-by-step approach to fat loss based on the clinically studied HCG diet protocol.
We are a New Zealand-owned business, based in Auckland, and everything we do is built around giving our customers the best possible chance of success — not just during the program, but long after it ends.
Our Story
Rose Cook was founded after experiencing first-hand what so many New Zealanders go through: trying diet after diet, losing a little weight, putting it back on, and never quite getting to a goal weight that actually stuck.
After discovering the HCG diet protocol and seeing the results it produced — not just on the scales, but in energy, confidence, and overall wellbeing — we knew we wanted to make this program accessible to New Zealanders everywhere. We formulated HC-SLIM drops specifically for the New Zealand market: a clean amino acid and Vitamin B12 formula with no hormones, no prescription required, and a straightforward program that anyone can follow.
What started as a small NZ operation has grown into one of New Zealand’s most trusted weight loss programs, with customers from Auckland to Invercargill — and increasingly, from around the world.
What Makes HC-SLIM Different
There are a lot of weight loss products out there. Here’s what sets HC-SLIM apart.
It Actually Works
Over 30,000 New Zealanders have used HC-SLIM since 2014. That’s not a marketing number — it’s the result of a program that delivers consistent, measurable results. Our customers typically lose 5–8kg on a 26-day round and 8–12kg on a 40-day round, with many completing multiple rounds to reach their total goal.
Simple to Follow
We’ve made the HC-SLIM program as easy as possible to understand and stick to. Every starter kit includes a complete digital diet guide with phase-by-phase instructions, a food shopping list, recipes, daily tips, and everything else you need to succeed. No gym required. No complicated meal prep.
Real NZ Support
When you buy from Rose Cook, you’re not just buying a product — you’re getting a support team. We offer NZ-based email support throughout your program, weekly check-in emails during your active phase, and access to a community of thousands of New Zealanders who have been exactly where you are now.
If you hit a stall, have a question about what you can eat, or just need encouragement to stay on track — we’re here.
No Hormones, No Prescription
HC-SLIM drops are formulated with 7 essential amino acids and Vitamin B12. They are not a hormone product, do not require a prescription in New Zealand, and are legal to purchase and use. They are safe for adults 18+ who do not have any contraindicated medical conditions.
Fast NZ Delivery
All orders are shipped from Auckland. Standard NZ delivery takes 1–3 business days, and your digital diet guide is emailed to you immediately after purchase so you can start preparing right away.
