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 liver health

Which peptides have been studied for liver health?
8 graded compounds: Semaglutide (A), Tesamorelin (A), Tirzepatide (A), Mazdutide (B), Thymosin Alpha-1 (B), Retatrutide (B), Survodutide (B), Glutathione (C). Grades run from A (approved, strong human outcome data) to F (contradicted, unsafe, or identity problems).
Which peptides for liver health were measured in people?
8 of 8: Semaglutide, Tesamorelin, Tirzepatide, Mazdutide, Thymosin Alpha-1, Retatrutide, Survodutide and Glutathione.
Which peptide has the strongest evidence for liver health?
Semaglutide: grade A, highest rung approved somewhere. Approved for type 2 diabetes, weight management and cardiovascular risk reduction.
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.
