Hey everyone,

Following up on my previous posts regarding my lab rat’s Tesamorelin protocol. We are currently finishing Week 3 of the study, and I’m looking for some collective wisdom on managing the ceiling for the remaining 9 weeks.

Current Subject Stats & Labs:

  • Protocol: 1mg Tesamorelin daily.
  • Baseline IGF-1: 200 (Z-score: +0.2).
  • Current Observations: The subject is tolerating the 1mg dose remarkably well. No edema, no carpal tunnel symptoms, and zero joint sensitivity noted in the logs so far.

The Research Dilemma:

The subject is scheduled for mid-point bloodwork next week. Based on the lack of side effects and the subject's initial responsiveness, I am anticipating an IGF-1 reading of 300+ . This would push the rat significantly past the upper reference range (~293 ) for its age bracket.

I am planning a 12-week total duration for this run, but I’m debating whether to keep the pedal down:

  • Path A: Maintain 1mg/day and hold the IGF-1 at 300+ for the full 12 weeks.
  • Path B: Titrate the dose down to 0.5mg/day to bring the IGF-1 back into a "high-normal" range (approx. 260–280 ).

Questions for the Community:

  1. For those who have pushed a subject into the supraphysiological range (300+ ), did you find the benefits to visceral adipose tissue reduction were significantly better than the 270 range, or is it a case of diminishing returns?
  2. If the subject is currently "side-effect free" at Week 3, is it common for the standard Tesa sides (water retention/glucose issues) to manifest later in the cycle if the dose isn't lowered?
  3. Given that Tesa's efficacy is dependent on the subject's endogenous pituitary response rather than being linear, is there any research-backed reason to avoid keeping the IGF-1 elevated at 300+ for the full 12-week block?

I’m trying to decide if "more is better" for this specific subject or if I should play it safe and keep the rat within a more natural peak. Any data points from your own labs would be appreciated!
