Cautions

  • Hunter Williams (2026-03-29, 04:30): "When it causes significant water retention, it can mask some of the fat loss that increasing growth hormone will do."
  • Hunter Williams (2026-03-29, 05:06): "And then it also elevates cortisol and prolactin levels with prolonged use."
  • Hunter Williams (2026-03-30, 06:00): "MK677 stimulates prolactin and cortisone and can raise those, which is not good."
  • Taylor Williams (2026-04-08, 18:25): "But when we talk about MK 677, the issue was you get these great results, but then you do it for four to six weeks and you're starving."
  • Taylor Williams (2026-04-08, 18:25): "And so obviously you have high cortisol, that's going to cause some issues. That's gonna cause, you know, exacerbate the blood sugar issues and then prolacin. It can make your mood off. it can affect sex drives and those things when you're raising prolactic, uh, past a certain level."
  • Hunter Williams (2026-03-30, 22:32): "Don't Stack GHRPs Together. You wouldn't need to take Ipermeralin with an MK677. I mean, i guess you could, but it just wouldn' t be the smartest thing to do."
  • Trevor (roc-LGn_fP0, 00:15:24.310): "You can run this long term as long as you really want to, as long as your blood glucose is monitored. Just don't be stupid."

Acute vs chronic specialist

Dr Bachmeyer often distinguishes acute (injury/infection) vs chronic (longevity/maintenance) dosing. Acute_signals + chronic_signals fields surface candidate contexts; full distillation pending Codex pass.

Acute context

  • 2025-07-05 @ 00:09:03.920
    “stuff for as long as you really want. You could run MK677 for 6 months”
  • 2025-07-05 @ 00:09:06.550
    “You could run MK677 for 6 months”
  • 2025-07-05 @ 00:09:06.560
    “You could run MK677 for 6 months straight. Never touch a PCT protocol”

Chronic context

  • 2025-07-05 @ 00:05:16.080
    “compounds today just so you understand what they are. MK677 and a cartery,”
  • 2025-07-05 @ 00:05:18.550
    “what they are. MK677 and a cartery,”
  • 2025-07-05 @ 00:05:18.560
    “what they are. MK677 and a cartery, right? It's I would call it the smart”
