Suggested Protocol
Clinical schedule: 1.6 mg subcutaneously twice weekly. A 5mg vial covers roughly a three-week replication arm at that cadence. Mechanistic dendritic-cell research sometimes uses lower daily dosing for different experimental purposes. Reconstitute in bacteriostatic water, refrigerate, use within the COA in-use window.
The Zadaxin clinical schedule is 1.6 mg subcutaneously twice weekly — roughly 3.2 mg per week. A 5mg vial is therefore close to a clean three-week-at-label-dose format: enough to run a short pilot or replication arm at full clinical cadence without carrying stranded peptide past the reconstitution window.
Documented Effects
Matches a short (≈3-week) full-dose replication of the Zadaxin twice-weekly schedule
Same 28-residue N-acetylated peptide as the 10mg vial and as Zadaxin
TLR9 agonism on plasmacytoid dendritic cells — a defined-receptor immune mechanism
Lower total mass reduces stranded peptide at the end of a short pilot
Established clinical safety and pharmacokinetics from 30+ country approvals
Batch COA with identity, purity, and endotoxin release criteria
Dosing Math
Three Weeks at Zadaxin Cadence, Within a Single Vial
1.6 mg twice weekly is about 3.2 mg per week. A 5mg vial covers roughly three weeks before any aliquoting wastage is accounted for — a natural fit for a short pilot at exactly the dose used in the drug’s clinical indication.
Same Molecule
No Difference in Chemistry Versus the 10mg Format
The peptide is identical: 28 residues, N-acetylated, synthesised to the Zadaxin sequence. Vial size is a sizing choice for the researcher, not a chemical variant.
Approved-Drug Context
Why That Matters for Interpretation
Tα1 is one of very few peptides in this catalogue with approved-drug backing somewhere in the world. Research using the 5mg vial can reference published PK, safety, and efficacy data from the approved programmes directly, rather than having to extrapolate from purely preclinical work.

Bacteriostatic Water 30mL
Sterile water with 0.9% benzyl alcohol as a bacteriostatic preservative — the solvent used to reconstitute every lyophilized peptide in your protocol. One 30mL vial handles roughly 15–30 reconstitutions, depending on peptide volume.
LL-37 10mg
The body's only human cathelicidin-derived antimicrobial peptide — 37 residues of broad-spectrum innate immunity. Disrupts bacterial membranes directly while also signalling to human immune cells as a cytokine-like alarm molecule.
Cartalax 20mg
Cartalax is the cartilage-positioned Khavinson tetrapeptide (Ala-Glu-Asp-Leu, AEDL), researched as a chondrocyte-selective successor to the joint-tissue extract Cartalin and typically paired with Pinealon in age-related musculoskeletal work.
