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 libido & reproductive health

Which peptides have been studied for libido & reproductive health?
4 graded compounds: Oxytocin (A), PT-141 (A), Kisspeptin-10 (C), Melanotan-2 (F). Grades run from A (approved, strong human outcome data) to F (contradicted, unsafe, or identity problems).
Which peptides for libido & reproductive health were measured in people?
4 of 4: Oxytocin, PT-141, Kisspeptin-10 and Melanotan-2.
Which peptide has the strongest evidence for libido & reproductive health?
Oxytocin: grade A, highest rung approved somewhere. Approved for labour induction; research on other uses is mixed.
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.
