Livagen vs Thymalin
Livagen and Thymalin are both immune peptides, which is why they get recommended interchangeably — but they are different compounds with different origins. The table below sets out the differences. We give no dosing guidance.
Side by side, in plain English — what each one is, where they overlap and where they genuinely differ.

The differences that actually matter
Both are classed as Immune peptides, so they get compared constantly and are often researched for overlapping reasons.
Route of administration differs — Livagen is typically subq, Thymalin is typically im (or subq). That alone changes how convenient each one is to keep up with.
Where they overlap: immune modulation, anti-inflammatory, cellular longevity signaling.
Reported mainly for Livagen: chromatin support.
What Livagen is
Livagen is a naturally occurring tripeptide bioregulator with the sequence Lys-Glu-Asp, originally identified from calf spleen tissue. Its mechanism involves interaction with specific immune cell populations, particularly lymphocytes, influencing their activity and differentiation pathways. While not acting through a singular receptor in the classical pharmacological sense, Livagen is thought to modulate gene expression related to immune cell function, helping to restore balance within the immune system. This biore
What Thymalin is
Thymalin is a synthetic analogue of a complex of peptides naturally found in the thymus gland. It is understood to influence the differentiation and maturation of T-lymphocytes, particularly pre-T cells, within the immune system. Its mechanism involves interaction with specific receptors on immune cells, leading to a modulation of cytokine production and the balance between various T-cell subsets, such as helper and suppressor T cells. By promoting the proper development and function of these key immune cells, Thym
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — Livagen and Thymalin are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between Livagen and Thymalin?
Both are classed as Immune peptides, so they get compared constantly and are often researched for overlapping reasons.
Can you log Livagen and Thymalin in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, Livagen or Thymalin?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
