05Administration Protocol

Parameter

Adamax

Thymalin

1. Reconstitution (if lyophilised)

Add sterile water or bacteriostatic water to lyophilised vial per manufacturer guidance. Roll gently — do not shake. Ensure clarity before use.

Add 1–2 mL saline or bacteriostatic water per 10 mg vial.

2. Route

Intranasal administration is the primary route in animal and exploratory human studies. Delivered via nasal spray or dropper to ensure mucosal absorption.Dolotov 2006 Smolnik 2000

Intramuscular — deltoid or gluteal. Rotate sites.

3. Timing

Variable. Single-dose protocols for acute cognitive tasks; chronic daily dosing for circadian rhythm normalization and sustained neuroprotection.

Morning preferred during cycle.

4. Storage

Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within manufacturer-specified timeframe.

Lyophilised: refrigerate, light-protected. Reconstituted: use immediately.

5. Needle

—

23–25G, 25–38 mm IM needle.

06Stack Synergy

Adamax

+ Semax

Moderate

View Semax →

Both Adamax and Semax are ACTH(4-10)-derived nootropics acting via melanocortin receptors and BDNF upregulation. Adamax has distinct amino acid modifications at positions 8-10, potentially offering complementary receptor binding profiles or metabolic stability. Stacking may amplify neurotrophic signaling and cognitive enhancement, though direct synergy studies are absent. Theoretical multi-pathway benefit.

Adamax: Research dose intranasal
Semax: 300–600 mcg intranasal
Frequency: Once daily, morning or pre-cognitive task
Primary benefit: Enhanced BDNF upregulation, cognitive performance, neuroprotection

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
