Metabolism, recovery and emerging research
Zenagamtide's early weight result is promising. Trial populations, duration, withdrawal and analysis explain why it cannot yet establish a ranking.
Read articlePain relief matters, but it cannot prove nerve regrowth. See what ARA-290 studies found in symptoms, corneal images, skin markers and function.
Read articleRepeated kisspeptin studies help explain what comes next: sustained patient benefit, usable delivery, meaningful fertility outcomes and better safety follow-up.
Read articleLonger zenagamtide studies are testing durable weight change, withdrawal and cardiovascular events. Each design answers a different patient question.
Read articleWhat an IGF-1 rise can tell you—and why CJC-1295 fat-loss and muscle claims need direct tissue and functional evidence.
Read articleBody fat, lean tissue and strength are different outcomes. Explore direct sermorelin studies and what a scan can—and cannot—show about recomposition.
Read articleGHRP-2 increased food intake in small controlled human experiments. The longer studies tell a more limited story about weight, nutrition and muscle.
Read articleSmall human studies found brief changes in heart pumping after hexarelin. Learn what those findings mean alongside mixed rodent results and unanswered clinical questions.
Read articleHexarelin's repeated-response experiments show partial, reversible GH attenuation under some conditions. They do not establish an optimal cycle or lasting health benefit.
Read articlePemvidutide's MRI substudy reported a favorable lean-loss share. Learn what that percentage means and why muscle strength needs separate evidence.
Read articleClosure time matters, but wound studies also need to show who healed, who dropped out, whether wounds reopened and how recovery affected daily life.
Read articleA growth hormone pulse is not the same as muscle growth. Understand the animal findings, the human evidence gap, and the difference between lean mass and strength.
