without concentration (in terms of understanding dose).</li><li>What is being used should generally be stated in terms of dose rather than volume. This is because concentration is also required for volume to be meaningful (#1 above) and because dose is much more readily interpretable to other people.</li></ol></div></div></div><div id="footer"> <span id="footer-subcontainer"> <span id="site-copyright">© 2025 <span translate="no" class="notranslate">Transfeminine Science</span></span> </span></div></div></body></html> |
