How long does Kisspeptin-10 take to work?
In the first week of Kisspeptin-10, lH and testosterone bumps within hours of dose. Subjective libido response varies. Around week 4, if on a short course, complete it. Effects don't compound the way they do with daily peptides. By week 8, off-cycle. Response varies between people, this is the commonly reported pattern, not a guarantee.
