Same Three Inputs, Four Sequences: How the Four Protocols Actually Differ
All four Peak Regenerate protocols use the same three inputs: red light, heat, and cold. Light starts in week 1 in every one. Heat enters in week 1, 2, 3, or 5 and cold in week 1, 4, 5, or 7, for Optimization, Recovery Enhancement, Reset Protocol, and Foundation in that order. By week 12, every one runs all three.
Every Peak Regenerate protocol runs on the same three inputs: red light, heat, and cold. None of the four drops one or swaps in something else. What changes is the order, meaning when heat and cold enter your week and how much room there is between them.
Why does light start in week 1 every time?
Across Optimization, Recovery Enhancement, Reset Protocol, and Foundation, red light begins in week 1. It is the easiest of the three on your body: a session does not ask your nervous system to adapt to anything the way heat or cold does. That makes it the one constant starting point, wherever you are starting from.
What actually differs between tiers?
| Protocol | Heat enters | Cold enters |
|---|---|---|
| Optimization | Week 1 | Week 1 |
| Recovery Enhancement | Week 2 | Week 4 |
| Reset Protocol | Week 3 | Week 5 |
| Foundation | Week 5 | Week 7 |
Optimization runs all three from day one, which suits people whose answers on sleep, recovery, and activity suggest they can take on all three right away. Foundation starts light alone for four weeks, then brings in heat and cold two weeks apart, each one only after the one before it has become routine. Reset Protocol and Recovery Enhancement sit in between, with heat and cold staggered by weeks.
Why does the spacing exist at all?
Mostly because of how habits form. A new routine tends to stick when you add one thing, get it running, and then add the next. In a well-known habit study, a new daily behavior took anywhere from 18 to 254 days to become automatic (Lally and colleagues, 2010). Each protocol adds heat first and cold two weeks later, so each one can settle before the next starts. The order is a design choice for building the habit, not a research requirement.
There is also a body-side reason to start cold gently. The sharp first reaction to cold fades with steady exposure over roughly 3 to 5 weeks (Tipton and colleagues, 2017). Spacing is a scheduling choice, not a limit on what any starting point is "allowed" to do. By week 12, every protocol has all three running.
What does this mean when you compare tiers?
A higher tier is not a harder version of a lower one. It is a shorter runway. Optimization and Foundation end up in the same place, three inputs running every week, on the same 12-week clock. They start from different points because they are built for different answers about sleep, recovery, activity level, schedule, and past experience with heat and cold.
If you already do some of this and stopped, or you are not sure whether the pace of a given tier fits you, the fastest way to find out is not guessing from a table. It is answering five questions once. And skipping ahead, adding heat and cold together before your plan calls for it, is not the same as getting results faster. It just throws away the spacing the plan exists to provide.
Common questions
What is the difference between the four protocols?
Only the order: when heat and cold enter the week, and how much space sits between them. All four run the same three inputs on the same 12-week clock.
Which protocol starts all three inputs at once?
Optimization, with light, cold, and heat all in week 1.
Which protocol has the slowest start?
Foundation, with heat entering in week 5 and cold in week 7.
Why are heat and cold staggered?
Habits stick when you add one thing at a time, so each protocol adds heat first and cold two weeks later. The order is a design choice, not a research requirement. Spacing lets each input settle before the next starts.
Is a higher tier a harder version of a lower one?
No. A higher tier is a shorter runway, not a harder version. Optimization and Foundation end in the same place.
Where to start
Find My Protocol matches your sleep, recovery, activity level, schedule, and heat and cold experience to one of the four sequences above and gives you the week by week plan for it. It takes about two minutes and does not require a purchase.
