90-day money-back guarantee Sealed daily doses No sweeteners, no fillers
The 90-Day Challenge.
One packet a day for 90 days. Here’s exactly what to expect, what we ask of you, and what happens if it doesn’t work for you.
- The commitment
- One packet daily, 90 days in a row
- The proof
- Your empty packets, kept in their bags
- The guarantee
- Not feeling better at day 90? Full refund.
The climb, day by day.
Day 1
Start
Mix one packet into 8 oz of anything, hot or cold. Coffee, water, a smoothie. Score yourself on the tracker below so you have a baseline.
Day 14
Make it a habit
Same time every day. Most people don't notice much yet, and that's normal. Collagen research is measured in weeks and months, not days.
Day 30
First check-in
Score yourself again. In our customer study, better rest was often the first thing people reported, within the first 30 days.*
Day 60
Second check-in
Score again and compare against day 1 and day 30. Slow changes are easier to see on paper than in the mirror.
Day 90
Decide
Compare your scores to day 1. Feeling better? Keep going. Not? Send back your three bags of empty packets for a full refund.

Track it, so you're not guessing at day 90.
Memory is a bad judge of slow change. Score these five on day 1, then again at each check-in.

How to take it.
Tear one packet
One a day. Don't double up to catch up.
Stir into 8 oz of any drink
Hot or cold. It's unflavored and dissolves in seconds.
Put the empty back in its bag
That bag is your guarantee. Keep all three.
The guarantee, in full.
Take one packet a day for 90 days
As directed, 90 days in a row. That's the whole commitment.
Put each empty packet back in its bag
Three bags of empties is your proof of consistent use. It's the only proof we ask for.
Not feeling better? Send the bags back
Mail the three bags of empty packets to us and we refund your full purchase price.
The guarantee covers a first-time purchase of the 90-day supply. [Confirm: who pays return shipping, and how many days the refund takes to process.] We’re putting the conditions here, up front, because a guarantee you discover on day 91 isn’t a guarantee.
Questions before you start.
Do I have to change my diet or start exercising?
No. The challenge is built to fit into the life you already have. One packet a day is the only change we ask for.
Can I put it in hot coffee?
Yes. It's fully hydrolyzed, dissolves in seconds, and has no flavor of its own, hot or cold.
What if I miss a day?
Take your packet as soon as you remember and keep going. [Confirm the policy on missed days for the guarantee.]
Which purchase does the guarantee cover?
A first-time purchase of the 90-day supply. Ninety days is the length the guarantee measures.
How do I get a refund?
Mail your three bags of empty packets to Rejuvenation Guaranteed, 2274 Schellsburg Rd., Queen, PA 16670, with your order number. [Confirm return shipping and processing time.]
Who shouldn't take it?
It contains egg, cod and pollock, so skip it if you're allergic to any of them. If you're pregnant, nursing, or taking medication, talk to your doctor first.
So what's your risk?
The worst case, you get your money back. The best case, you start feeling great again.
