Compounds in this category
Thymalin 10mg
Thymalin is a bioregulatory peptide derived from the thymus gland, consisting of a complex of polypeptides that support immune system modulation, thymus function restoration, and healthy aging.
- Strengths:
- 10mg
- Form:
- Lyophilized Powder
Thymosin Alpha-1 10mg
Thymosin Alpha-1 (Tα1) is a 28-amino acid thymic peptide approved in over 35 countries for immune modulation. A 2024 BMC Infectious Diseases study confirmed its role in restoring immune response in HIV immunological nonresponders. A 2025 NIH PMC study showed Tα1 alleviates inflammation and prevents infection. Research demonstrates enhanced T-cell maturation (CD4+/CD8+), dendritic cell activation, and natural killer cell activity enhancement.
- Strengths:
- 10mg
- Form:
- Lyophilized Powder
LL-37 10mg
LL-37 is the only human cathelicidin antimicrobial peptide, consisting of 37 amino acids with broad-spectrum activity. A 2025 MDPI review detailed its mechanism against bacteria, viruses, and fungi. An NIH PMC study confirmed LL-37's potential for treating polymicrobial infected wounds. Research demonstrates membrane disruption activity, biofilm prevention, immunomodulation, and wound healing promotion through epithelial cell migration.
- Strengths:
- 10mg
- Form:
- Lyophilized Powder

Frequently asked questions
Is endotoxin testing reported?
Endotoxin results are shown only where the uploaded Certificate of Analysis for that lot reports them.
Are these sterile products?
They are laboratory research chemicals. Any sterility or endotoxin data is limited to what the lot COA documents.
Can I verify a vial lot number?
Yes. The lot number on the vial matches the lot on the linked COA in our Certificate of Analysis library.
