RESEARCH
Free research tools
Calculators, charts, and mechanism briefs we built for our own bench and put online so other labs can use them. No login. No download form.
CALCULATOR
Reconstitution calculator
mg + target concentration → bacteriostatic water mL + U-100 tick math.
GUIDE
Reconstitution & storage guide
Step-by-step protocol, storage temps, post-reconstitution stability windows.
MECHANISM
Mechanism briefs
7 peer-reviewed mechanism summaries (BPC-157, TB-500, CJC-1295, Ipamorelin, GHK-Cu, Semaglutide, Tesamorelin).
EXPLAINER
How to read a peptide COA
Chromatogram interpretation, peak purity vs net peptide content, common pitfalls.
EXPLAINER
RUO vs API grade
What changes between research and pharmaceutical grade material, and why it matters for your assay.
SOP
Our 9-step lab process
SPPS → HPLC → MS → analytical → release. Public transparency document.
