The cost of getting it wrong
Underdosed vials from an unverified seller
Research results compromised. Money wasted on product that doesn't meet stated purity.
Paying retail markup on wholesale-priced compounds
Most retailers apply 500-1000% markup. That adds up to hundreds or thousands per year.
Trusting a recycled or fabricated COA
Some suppliers reuse old COAs across batches, or present another company's analysis as their own.
A single bad order on a 10-vial box can cost £150-300+. This guide costs £29.99 and teaches you how to verify everything before you spend.
