Guides

Background reading for anyone who wants to understand the research-peptide market before spending money in it. The guides below cover first steps, lab reports, crypto payments, pen supplies, terminology and more. They are educational material for research purposes, not medical advice.

Getting Started with Tirzepatide
An orientation for newcomers to GLP-1 research peptides: realistic expectations, how vendors and group buys work, shipping and returns, and why quality control matters.

Testing 101
A walkthrough of the Certificate of Analysis. Learn what purity and fill figures actually tell you and how to arrange an independent test of an order you received.

Crypto 101 for Peptide Purchases
Stablecoins, networks and wallets explained for first-time crypto buyers. It also shows how checkout here sends your payment into escrow, so the brand is paid only once your order has arrived.

Injection Pens 101
An explainer of pen and cartridge supplies: the parts of a reusable pen, what the cartridge holder is, and the terms you will see on supply listings.

Compounding Sources
How 503A and 503B compounding pharmacies differ, where their API comes from, who the FDA-registered labelers are, and which form of tirzepatide they work with.

Residual Solvents
The organic solvents used during solid-phase peptide synthesis (SPPS), including TFA and Class 1 solvents, the standards that limit them, and the testing options available.

Dictionary of Terms
Plain definitions for the acronyms and jargon you will meet across forums, COAs and listings, from ADA and LTEV to SPPS and USP.
