What this section covers

• Reconstitution and handling. Working with lyophilised material, bacteriostatic water, and the arithmetic of concentration.
• Storage and stability. Which compounds are fragile, what temperature excursions in transit actually do, and why a certificate issued at manufacture says nothing about condition on arrival.
• Reading a certificate of analysis. Which fields carry information, which are decoration, and how to check that a document refers to the batch in front of you.
• Assessing a supplier. The documentary questions worth asking before an order, covered in more depth under vendor reviews.
• Comparing cost. Normalising price per milligram and adjusting for purity, covered under pricing analysis.

What this section does not cover

There are no dosing protocols here, no cycle designs, and no guidance on whether any person should use any compound. That is not an oversight or an abundance of caution about liability. It is a limit on what this site is competent to tell you.

We are qualified to say what a vendor has documented and what the analytical methods establish, because those are documentary questions that anyone can check against the same paperwork. Clinical questions are not documentary questions, and they belong with a qualified healthcare professional who knows the individual case. Our position on this is set out in full on the editorial team page.

How to use these guides

Most people arrive here with a specific question rather than an interest in reading through. The guides are written to be entered in the middle: each one states its conclusion early and then shows the working, so a page can be skimmed for the answer and re-read for the reasoning.

Where a guide depends on a figure that moves, such as a market price or a purity baseline, the figure is dated on the page and indexed from public listings rather than quoted from memory.
