The 28-day rule for bacteriostatic water (and what it doesn't tell you about your peptide)
Where the 28-day BUD comes from, what the benzyl alcohol preservative actually protects against, and why your peptide may have a shorter shelf life than the water it's dissolved in.

Common reconstitution mistakes (and what to do about them)
Ten reconstitution mistakes that come up regularly in peptide use, what they look like, why they happen, and what to do if you've made one.

How long does a peptide vial last? The math, with examples.
Calculate doses per vial and vial duration from total content, dose size, and frequency — then see why the beyond-use date often matters more than the dose math.
