Marcus Chen
Marcus Chen covers tissue repair, muscle recovery, and immune system studies. He reads injury models, inflammation markers, and recovery timelines. His posts compare what animal work shows against human observational data. He reports effect sizes and confidence intervals without suggesting any protocol. He keeps a steady pace and flags when a finding has not been replicated.

What the studies show about CJC-1295 in 2026
One injection of CJC-1295 kept growth hormone and IGF-1 elevated for days in controlled trials, but no human study has connected that to muscle, recovery, or body-composition benefit.

Three 2026 studies tie Follistatin 344 to artery and prostate effects
Arteries and prostate cells took center stage in three 2026 studies. Follistatin 344 reduced artery plaque in one mouse model and improved blood vessel function in hypertensive rats, but a separate study linked follistatin to prostate cancer resistance.

A resistance training review keeps MGF in the IGF-1 exercise story
A 2026 review of resistance training and nutrition names MGF as one of the local IGF-1 isoforms involved in exercise adaptation. Two other newly indexed studies cover liver and anti-inflammatory pathways, not MGF itself.

LL-37 runs high in oral cancer and low in severe sleep apnea
Three 2026 studies measured LL-37 in saliva and blood. Levels rose with oral cancer and fell as sleep apnea worsened, adding to mixed biomarker evidence.

A GHRP-2 test can sort two forms of adrenal insufficiency
A retrospective study in 69 patients found that a GHRP-2 cortisol cutoff below 12 micrograms per deciliter was specific for hypothalamic adrenal insufficiency when CRH results looked normal.

A mouse study links KPV to slower fat cell formation
A 2026 cell and mouse study found that KPV reduced fat cell formation and eased signs of obesity on a high-fat diet. The work adds a metabolic angle to a peptide mostly studied for gut, skin, and mouth inflammation.

A rat study links MK-677 to effort choices
A rat study found that moderate doses of MK-677 changed how rats weighed effort against reward. A review of six peptides found human evidence for MK-677 remains limited and mixed.

A case report ties sermorelin and GH use to a neck bone spur
A 2026 case report describes a 62-year-old man who had trouble swallowing because of a bony spike in his neck after about 20 years of growth hormone and sermorelin use. The report adds a clinical note to an evidence base that focuses mostly on hormone levels, not bone structure.

Clinic notes show BPC-157 use rising fastest among younger men
A 2026 clinical note review found documented BPC-157 use rose 33-fold over six years, with new users skewing younger and male. A separate rat tendon study showed TB-500 or the combination improved architecture more consistently than BPC-157 alone.
