The Research Peptide Market Is a Minefield
Purity Roulette
Most peptide vendors don't provide third-party testing. You're trusting a label with no verification. Underdosed or contaminated compounds waste time and money.
Inconsistent Supply
Vendors go out of stock, change formulations, or disappear entirely. Running a consistent protocol is impossible without a reliable supply chain.
Zero Transparency
No batch numbers, no COAs, no customer service. Most peptide sites are anonymous storefronts with no accountability.
