Daily during cycle, any time.
Morning preferred during cycle.
4. Storage
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
Lyophilised: refrigerate, light-protected. Reconstituted: use immediately.

06Stack Synergy
Pinealon
+ Epitalon
ModeratePinealon (neuroprotection) + Epitalon (telomerase activation) form the canonical Khavinson "longevity stack" — both pineal-derived bioregulators with complementary axes. Pinealon supports neuronal antioxidant defense; Epitalon supports telomere maintenance. Anecdotally cycled together 1–2× per year.
- Pinealon
- 5–10 mg SQ · daily × 10 days
- Epitalon
- 5–10 mg SQ · daily × 10 days (overlap or alternate)
- Primary benefit
- Neuroprotection + telomere preservation
Thymalin
+ Thymosin α-1
ModerateThymalin is a polypeptide complex; Thymosin α-1 is a single purified peptide. Both target the thymus-axis but at different levels — Thymalin restores broad thymic signaling; Tα-1 provides a specific molecular activator. Anecdotally combined for elderly immune support.
- Thymalin
- 5–10 mg IM · daily × 7 days
- Thymosin α-1
- 1.6 mg SQ · 2× weekly during the cycle
- Primary benefit
- Broad thymic restoration + targeted immune activation
