05Administration Protocol

Parameter
5-Amino-1MQ
Thymalin
1. Form
Oral capsule. No injection.
Add 1–2 mL saline or bacteriostatic water per 10 mg vial.
2. Administration
Take with water, fasted preferred.
Intramuscular — deltoid or gluteal. Rotate sites.
3. Timing
Morning fasted.
Morning preferred during cycle.
4. Storage
Room temp ≤25 °C, dry place.
Lyophilised: refrigerate, light-protected. Reconstituted: use immediately.
5. Caveat
Monitor B-vitamin status with chronic use.
23–25G, 25–38 mm IM needle.

06Stack Synergy

5-Amino-1MQ
— no documented stacks
Thymalin
+ Thymosin α-1
Moderate
View Thymosin α-1

Thymalin 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
