Peptide guides

Plain-language explanations of peptide pharmacokinetics, lab reports, bloodwork and unit math.

• How to read a peptide COA

  HPLC purity, mass spec identity, lot matching, endotoxin and sterility testing, and red flags.

• Peptide half-life explained

  How much remains after each half-life, steady state, accumulation and peak-to-trough swings.

• mg, mcg and IU conversions

  mg to mcg, why IU is substance-specific, and concentration after reconstitution.

• Baseline labs for training

  Which blood tests to start with, how often to repeat them, and keeping results comparable.

• What's in a bodybuilder blood panel

  CBC, metabolic panel, lipids, hormones, thyroid and IGF-1, and how training skews results.

• Hormone panel basics

  Total and free testosterone, estradiol, SHBG, LH, FSH, timing and unit conversions.

• IGF-1 blood test explained

  The standard blood marker of growth-hormone activity, age-specific ranges, and what moves it.

• Glossary

  37 pharmacokinetics and peptide-quality terms defined.

• Half-life comparisons

  32 side-by-side comparisons with decay curves.

• Half-life chart

  Reference half-lives for every peptide in the catalog.
