Guide Nº 1
Buying Peptides Without Getting Ripped Off
Researchers bought semaglutide from three online sellers and had it independently tested: purity came back at 7.7 to 14.37 percent against 99 on the label, and the vials still held more drug than the label claimed. This guide walks through what testing keeps finding inside real vials, and the handful of checks that catch the worst of it before you pay.

Guide Nº 2
How to Read a Peptide COA
A certificate of analysis is the one document that says what is actually in a vial, and almost nobody is ever shown how to read one. Two real certificates marked up line by line: what each row means, which tests matter and which are decoration, and the tricks a bad certificate plays.

Guide Nº 3
Reconstitution Math, Without the Hand-Waving
Adding water to a vial is division, twice, with one multiplication at the end. This guide works the arithmetic out by hand so you can check any chart instead of trusting it, including ours. It contains no doses and suggests none.

Guide Nº 4
The GLP-1 File
The one category where the evidence is genuinely strong, which moves the risk somewhere else. Semaglutide, tirzepatide, retatrutide, cagrilintide and mazdutide: what the trials actually showed, what the grey market sells instead, and the one published test of what was really inside the vials.

Guide Nº 5
What Studies Gave vs What People Take
All 65 compounds in one set of tables: the dose studies actually gave people, the dose that circulates in practice, and how the two compare. The finding the tables carry: for 26 of the 65, there is nothing to compare against, because no human dose has ever been published.

Guide Nº 6
The Dose Record
The full card file. Every compound gets its own enclosed card: the published human dose record beside what actually circulates, where the circulating number really came from, and the mistake that costs people. Every figure traces to a named source.
