Thymalin

Pen Peptide manufacturer protocol (20mg pen = 200 clicks × 100 mcg):

Standard course: 10–20 clicks (1–2 mg) × once daily subcutaneous or intramuscular × 10 days.

• Start: 10 clicks (1 mg) first 3 days to assess tolerance.

• Standard: 15–20 clicks (1.5–2 mg) per day.

• Timing: evening, before bed (synergy with nocturnal melatonin increase).

Set pen programmer to 10, 15, or 20 clicks. Subcutaneous injection in abdomen or thigh (short needle 4–6 mm at 90°), or intramuscular in deltoid muscle or upper outer quadrant of buttock. Rotate injection sites. After injection — wait 10 seconds before withdrawing needle.

Duration: 10 days — 1 pen covers full course.

Prophylaxis: 2–4 courses/year. Optimal October-November (before URTI season) and February-March. For chronic processes — repeat every 3 months.

Anti-aging stack (Khavinson): Thymalin 1 mg + Epitalon 5 mg subcutaneous daily × 20 days, repeat every 6 months.

Can be combined with: Thymosin Alpha-1, Bronchogen (for respiratory), Prostamax (for men), Epitalon (anti-aging).

Storage: in refrigerator at 2–8°C, do not freeze.

Before starting — DOZA specialist consultation, especially for autoimmune diseases in exacerbation phase.

Thymalin is a peptide bioregulator extracted from calf thymus (thymus gland), developed by Vladimir Khavinson's school at the St. Petersburg Institute of Bioregulation and Gerontology in the 1970s-80s. One of the first industrial immunomodulators in the USSR/Russia — used in clinical practice for decades for post-infectious recovery, chronic recurrent inflammations, and autoimmune skin diseases.

Unlike synthetic Thymosin Alpha-1 or Thymopentin, Thymalin is a natural peptide complex containing several short thymic peptides (including Thymulin/Zn-FTS). This makes it more "physiological" for the body — replicating the multi-component pattern of natural thymic factors that mature T-lymphocytes in the thymus.

Mechanism: normalizes T-cell ratio (CD4+/CD8+), stimulates IL-2 production, activates macrophage phagocytosis, increases serum immunoglobulins. Unlike anti-inflammatory drugs (NSAIDs, corticosteroids) — does NOT suppress immunity but normalizes it. Especially effective in "exhaustion immunodeficiency": frequent URTIs (≥4 episodes/year), chronic fatigue, slow wound healing.

Pen Peptide produces Thymalin in pre-mixed pen format 20mg (200 clicks × 100 mcg), purity ≥98%, GMP standard + stabilized MSSPT formula. Manufacturer protocol: 10–20 clicks × once daily subcutaneous or intramuscular, 10-day course — 1 pen fully covers the course. Prophylactically 2–4 courses per year (especially in autumn before URTI season).

Thymalin is a thymus (thymus gland) extract, one of the first bioregulatory peptides by Khavinson school (St. Petersburg Institute of Bioregulation and Gerontology), developed in early 1970s. Normalizes T-cell immune function: stimulates T-lymphocyte maturation in thymus (especially important with age-related thymic involution after 40 years), restores Th1/Th2 balance, increases natural killer (NK-cell) activity and neutrophil phagocytic function (Khavinson & Morozov, Neuroendocrinol Lett 2003). In clinical observations (n=200+): immune status improvement in 78% of patients, 40-60% reduction in URTI frequency, 30% faster recovery from infections (Anisimov et al., Biogerontology 2006). One of the oldest peptide bioregulators with 40+ years of clinical experience in immunology and gerontology.
