research market · not for human use

A lit region shows where studies measured an effect, not that a compound works there. Most research-market compounds are not FDA-approved.

Evidence grades come from the published literature; no vendor can pay for a grade or a ranking. Some outbound links are affiliate links; they never affect grades, scores or order.

short answers

questions about peptides for heart health

Which peptides have been studied for heart health?
6 graded compounds: Liraglutide (A), Semaglutide (A), Tirzepatide (A), SS-31 (B), Hexarelin (C), TB-500 (D). Grades run from A (approved, strong human outcome data) to F (contradicted, unsafe, or identity problems).
Which peptides for heart health were measured in people?
4 of 6: Liraglutide, Semaglutide, Tirzepatide and SS-31. The others have animal or cell studies only for heart.
Which peptide has the strongest evidence for heart health?
Liraglutide: grade A, highest rung approved somewhere. Approved for type 2 diabetes and weight management, with cardiovascular outcome data.
What does a lit region on the body map mean?
That published studies measured an effect there. Mint means it was measured in people; periwinkle means animals or cells only. A lit region is not a claim that a compound works there.
Is this medical advice?
No. PeptideTech is an independent information service. Research-market compounds are sold as research chemicals and most are not approved for use in people.
