Can I get in legal trouble for buying research peptides?

Short version: for an individual buyer in the US, criminal prosecution is uncommon, but the risk is not zero, and it isn't a clean legal product either. Most popular research peptides (BPC-157, GHRP variants, and similar) are not DEA-scheduled controlled substances, so possession alone is generally not a federal crime. What they are, per the FDA, is unapproved new drugs. The "research use only" or "not for human consumption" label keeps the sale technically lawful for lab use, but it does not make them legal to buy or import for human use. The Florida Healthcare Law Firm puts it plainly: buying or using research-only peptides for human consumption violates FDA regulations and could carry consequences for buyers and sellers. In practice, FDA and DOJ enforcement has gone after vendors, compounders, and clinics making therapeutic claims, not individual purchasers. Imports are the real friction point: US Customs and Border Protection can detain and destroy shipments flagged as unapproved drugs. These products are not approved for human consumption, and we don't give legal advice. For your situation, talk to a licensed attorney.
