Tools for the
working hand.
Practical, single-purpose calculators for anyone handling research peptides — dose math, reconstitution steps, compound matching, and regulatory lookup. Each one is its own workspace.
Find the exact volume.
Calculate injection volume from vial size, concentration, and target dose. Accounts for TFA contamination and purity.

Mix it cleanly.
Interactive step-by-step protocol for reconstituting lyophilized peptides safely with bacteriostatic water.

Match goal to molecule.
Filter compounds by health goal, evidence level, and administration route to narrow the field before you dive into profiles.
“FDA approved for obesity — strongest weight loss evidence (14.9% STEP-1)”
“Largest weight loss in any Phase 3 trial (22.5% SURMOUNT-1)”
“FDA approved; longest established GLP-1 safety record”
“FDA approved (Vyleesi) — only approved peptide for sexual dysfunction”
“Intranasal; social bonding, anxiety, potential sleep benefits”
“GHRH analog with human Phase I data; historically used in adult GH deficiency”
“GHRH analog; synergistic with Ipamorelin for GH release”
“Most selective GHSR agonist — minimal cortisol/prolactin spillover”
“Strongest animal data for tendon/ligament repair; now 503A prohibited”
“RegeneRx Phase II cardiac data; actin-regulatory tissue repair mechanism”
“Approved in 35+ countries; strongest clinical data of any research immune peptide”
“Decades of collagen and wound healing research; topical use well established”
“BDNF/NGF upregulation; Russian registration for stroke/cognitive decline”
“Anxiolytic without sedation/tolerance — GABAergic + BDNF mechanism”
“Oral GHSR agonist (~60–70% bioavailability) — convenience advantage”
“Telomerase activation claim; limited but interesting Khavinson research”
“Direct delta wave sleep induction without GABA mechanism”
“Most potent GHSR agonist; Japan-approved for diagnostic use”
