05Administration Protocol

Parameter
Crystagen
SS-31
1. Route
Subcutaneous injection — presumed from bioregulator class convention. Specific anatomical sites not standardized.
Add bacteriostatic water per label. Light-protected handling.
2. Reconstitution
Protocol not standardized. If lyophilized, sterile water or bacteriostatic saline typical for peptide bioregulators.
SQ — abdomen or thigh. Rotate sites.
3. Timing
Not specified. Bioregulator protocols vary — some practitioners advocate evening dosing, others morning.
Morning fasted; pre-workout for exercise-augmented mitochondrial stress.
4. Storage
Lyophilized: room temperature, light-protected. Reconstituted: refrigerate, use within days to weeks depending on preservative.
Lyophilised: refrigerate, light-protected. Reconstituted: refrigerate ≤30 days.
5. Needle
29–31G, 4–8 mm insulin syringe.

06Stack Synergy

Crystagen
+ Vilon
Multi-pathway
View Vilon

Vilon (Lys-Glu) activates T-helper cells via apoptosis reduction, while Crystagen activates B-cells. Dual T/B immune modulation in aging models may provide complementary thymic-immune support within the Khavinson bioregulator framework. Both target splenic immune aging through distinct lymphocyte subsets.

Broader thymic-immune coverage (T-cell + B-cell)
SS-31
+ MOTS-c
Moderate
View MOTS-c

SS-31 and MOTS-c address mitochondrial decline through complementary axes. SS-31 protects existing mitochondrial structure (cardiolipin binding, cristae stabilisation). MOTS-c upregulates AMPK/PGC-1α, triggering biogenesis of new mitochondria. Together they pair preservation with renewal — anecdotally favoured in healthspan and post-cardio-event recovery protocols.
