How can peptides help me?
Emerging clinical evidence

Can peptides support my immune system?

Thymic peptides are the credible part of this category: thymosin α-1 has phase III data in sepsis and is approved in several countries for immune modulation.

Who this applies to

Problems people bring to this category

  • Frequent or slow-clearing infections
  • Immune support during sepsis and critical illness
  • Chronic viral infection as adjunct therapy
  • Age-related decline in T-cell function

Compounds studied

Peptides used for immune function

Thymosin Alpha-1

Phase III

Restores T-cell function; phase III sepsis trial data and approved use for hepatitis in some jurisdictions.

BPC-157

Preclinical

Gut-barrier and anti-inflammatory effects in animal colitis models, which indirectly affect immune signalling.

Honest reading

What the evidence actually shows

  • The strongest thymosin α-1 data are in acutely ill hospitalised patients, not healthy people seeking prophylaxis.
  • Effect sizes in sepsis trials were meaningful but not consistent across all endpoints.
  • In the US, thymosin α-1 is not an approved compounding substance, which sharply limits legitimate access.

Expectation setting

What peptides will not do here

  • It will not prevent common colds or replace vaccination.
