Why Progress Can Feel Slow in CDR2 (Phase 2) of Salugenesis

If you’ve been doing “all the right things” and still feel like your recovery is crawling, there’s a very real (and often overlooked) reason: CDR2 is the rebuild phase—and rebuilding is resource-heavy, subtle, and rarely linear.

In Dr. Robert Naviaux’s salugenesis model, healing moves through three required stages (CDR1 → CDR2 → CDR3). Importantly, the steps can’t be skipped or reversed—your system has to complete each phase in sequence.

Let’s break down what’s happening in CDR2, and why it can make progress feel slow even when you’re genuinely improving.

What CDR2 Actually Is: “Biomass Replacement”

CDR2’s job is replacement and rebuilding. After the initial threat is contained/cleaned up in CDR1, the body has to restore what was lost—cells, structure, and functional capacity. Naviaux describes CDR2 as the phase where stem cells are recruited to replace lost biomass and restore tissue integrity.

This phase is metabolically unique: it relies heavily on aerobic glycolysis (Warburg-style metabolism) and a “growth” mitochondrial phenotype (often described as M0 mitochondria) that supports building new cellular material.

Translation: your body is spending a lot of its available energy on construction, not on feeling amazing.

Why CDR2 Often Feels Slow (Even When It’s Working)

1) Healing in CDR2 is energy- and resource-consuming

Salugenesis is explicitly described as energy- and resource-consuming, and Phase 2 is where a lot of those resources get allocated to growth, repair, and rebuilding. So it’s common to notice things like:

• fatigue that improves slowly

• “two steps forward, one step back” patterns

• needing more recovery time after normal activities

2) Your body is rebuilding parts, not just reducing symptoms

CDR2 is about restoring capacity (muscle, connective tissue integrity, mucosa, mitochondrial network readiness, etc.). Symptom relief can lag behind capacity-building.

A useful frame: you can be getting better while still feeling stuck, because the improvements are happening “under the hood.”

3) Cells can’t form stable teamwork yet

One of the most important (and underappreciated) reasons CDR2 feels slow: during CDR2, cells are dividing and migrating, and Naviaux notes they’re unable to establish long-term metabolic cooperation while their location is changing. Only after growth/migration stop and durable connections (like gap junction communication) return can the system reliably transition onward.

Translation: your body is still reorganizing. Stability comes later.

4) Any lingering “danger signal” can keep you looping backward

The CDR is strongly influenced by metabolic signaling, including extracellular ATP (eATP) and purinergic signaling, which helps drive transitions through the healing cycle. If threat signaling stays “on,” the system may stall or oscillate between stages.

Common real-world “loop-back” drivers include:

• ongoing gut permeability/dysbiosis or food triggers

• hidden infections or inflammatory exposures

• sleep disruption

• overtraining/overexertion (your “capacity” gets exceeded)

• chronic stress physiology that keeps the body in a guarded state

5) CDR2 has real risks if the terrain isn’t ready

Naviaux also points out that in CDR2, cells with excessive damage may exit into senescence, and that fibroblasts/scar “walling-off” can occur when complete clearance didn’t happen earlier. This is one reason we’re careful about forcing aggressive protocols too early—your body needs the right conditions to rebuild cleanly.

Signs You Might Be in CDR2 (and not “failing”)

You may be in a CDR2 pattern if you notice:

• fewer “crashes,” but stamina is still limited

• symptoms are less intense but more persistent

• you tolerate gentle routines better than big interventions

• you’re sensitive to overdoing it (exercise, fasting, detox, heavy schedules)

• improvements show up first as stability (sleep consistency, digestion regularity, calmer reactivity) rather than dramatic symptom disappearance

How We Support Momentum Through CDR2

The goal in CDR2 isn’t “push harder.” It’s support rebuilding without re-triggering danger signaling.

Practical priorities:

• Pacing + capacity-based progression: increase output only when recovery is predictable

• Protein + micronutrient sufficiency: rebuilding requires raw materials

• Sleep architecture protection: healing cycles depend on restorative sleep cycling

• Gut-first consistency: reduce immune friction so the body can stay in rebuild mode

• Inflammation modulation without suppression: calm the system while still allowing repair signaling

• Strengthen autonomic safety cues: because threat perception changes biology

The Bottom Line

CDR2 often feels slow because it is slow by design. It’s the stage where your body replaces lost biomass, reorganizes tissue structure, and rebuilds functional reserve—using a metabolism geared toward construction.

If you’re in CDR2, the win is not “perfect days.” The win is:

• fewer setbacks,

• more stability,

• and gradual expansion of what your body can tolerate.

That’s not stalled healing—that’s healing in progress.
