Educational reference only. Individual responses vary. Consult healthcare provider before use.

Vial Size
20 mg
Reconstitution
2 ml BAC water (10 mg/ml)
Dose
1 mg (10 units) — reflects Russian practice, not a Western-validated dose
Timing
AM
Frequency
Once daily
Duration
Short ~10 day courses (community / Russian practice)
Protocol Notes
Khavinson thymus dipeptide (Glu-Trp / EW) isolated from Thymalin. Doses reflect Russian clinical convention (intranasal/SC), not Western trial validation. Single-lab evidence base.

Why This Dosing Protocol

What dose do people use? Short courses (~1 mg/day, intranasal or SC, ~10 days) reflecting Russian clinical convention — not Western-validated numbers.

Why short courses? Matches the documented Russian intermittent-course practice, repeated seasonally.

How Thymogen Works

Short-Peptide Bioregulator — Thymus / Immune (Single-Lab Evidence)

Target → Signal → Effect → Outcomes

1
Target

Immune Cells / Thymic Regulation

Thymogen is the dipeptide Glu-Trp (EW), isolated from the Thymalin thymus extract and then synthesized. It is proposed to act on T-cell differentiation and immune balance, framed within the Khavinson bioregulator model.

2
Cellular Signal

T-Cell / Immune Activation

Rodent and Russian clinical reports from the originating group describe immune activation and T-cell effects. Single-lab evidence — a plausible immune signal, not a Western-validated pathway.

3
Systemic Effect

Immune Modulation + Rodent Lifespan/Anti-Tumor

A rat study reported modest max-lifespan increase and fewer spontaneous tumors. Russian clinical practice used it as an immunocorrector. No Western randomized trials or independent replication.

4
What You Notice

Reported Immune Support (Unverified in Trials)

Users and Russian practice describe cold/flu-season immune support, but no controlled human trial confirms a felt effect. Treat as reported, not proven.

What Makes This Peptide Different

Thymogen is the isolated/synthesized Glu-Trp dipeptide from Thymalin — the best-evidenced of the synthetic bioregulators here, with real rodent data plus decades of Russian clinical use, but still single-lab and without Western trials.

Thymogen FAQ: Buying, COA, Storage & Research

What is Thymogen?
Thymogen is a synthetic thymus dipeptide — Glu-Trp, or EW — isolated from the Thymalin extract and then synthesized, part of the Russian Khavinson bioregulator family. It is marketed for immune support. Rodent studies and Russian clinical reports from the originating group describe immune-modulating effects.
How strong is the evidence behind Thymogen?
Moderate by the standards of this family — there is real rodent data (lifespan and anti-tumor) plus Russian clinical use — but it is single-lab, older, and without Western randomized trials or independent replication. Sold as a research chemical in the West.
How is Thymogen different from Thymalin?
Thymalin is the natural multi-peptide thymus extract; Thymogen is the single isolated/synthesized dipeptide (Glu-Trp) from it. They are related but not identical, and each has its own evidence base.
How long does reconstituted peptide last?
Once mixed with bacteriostatic water, peptides remain stable for up to 4 weeks when refrigerated at 2-8°C (36-46°F). Unopened powder can last 1+ year in the freezer. Get our complete Storage & Travel Guide.
Is this peptide legal to purchase?
Peptides sold "for research purposes only" are legal to purchase in the US, but are not FDA-approved for human use outside of specific medical applications. Always consult a healthcare provider before use.

Thymogen Dosage: What the Research Shows

No modern trial set a Thymogen dose. Russian practice used ~100mcg short courses — here's the reconstitution math and why a 20mg research vial doesn't fit.

side-effects

Thymogen Side Effects: What the Evidence Shows

Its makers call it nearly side-effect-free after decades of Russian use. Independent Western data barely exists — here's what that gap hides.

Thymogen Results: Week-by-Week Timeline

Thymogen has no modern human efficacy trial — so what shapes its reported timeline? Old Russian course data and labeled community reports, week by week.
