Reset Biology Synthesis

Reset Biology suggests asking the practitioner to weigh Hunter's newer direct-LR3 framing: Hunter (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 2026-03-30, 1:44, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/): "There's a very good use case a few times a year for IGF-1 LR-3 in that context." Hunter (why-igf-1-levels-dont-matter-as-much-as-you-think--55c5dbf4, 2026-03-29, 11:39, https://library.hunterwilliamshealth.com/p/why-igf-1-levels-dont-matter-as-much-as-you-think--55c5dbf4/): "the decision to use HCH peptides or HTH should focus on symptom resolution rather than laboratory numbers."

Where they agree

Hunter (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 2026-03-30, 8:53, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/): "it enhances glucose uptake in the muscle, improves insulin sensitivity, if used properly, again, And then also too, it improves lipolysis, the breakdown of fat." Taylor (nkOr0jCzn18, 00:02:44.720, https://youtu.be/nkOr0jCzn18): "the biggest benefit is lean muscle mass." Trevor (roc-LGn_fP0, 00:08:46.000, https://youtu.be/roc-LGn_fP0): "IGF-1 is anabolic systemically and that means bones." Hunter (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 2026-03-30, 19:40, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/): "I like four to eight weeks on, then equal or longer off period." Taylor (nkOr0jCzn18, 00:17:00.360, https://youtu.be/nkOr0jCzn18): "I like taking it for 10 days and then cycling off um four weeks."

Where they differ

Newer Hunter (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 2026-03-30, 19:08, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/): "i prefer to do it post workout." Older Hunter (igf-1-lr3-a-use-guide-for-practical-research-purposes--d337bad5, 2026-03-29, 12:32, https://library.hunterwilliamshealth.com/p/igf-1-lr3-a-use-guide-for-practical-research-purposes--d337bad5/): "IGF wanted 100mg like 30 minutes before my lift was a phenomenal pump." Newer Hunter (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 2026-03-30, 19:40, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/): "I like four to eight weeks on, then equal or longer off period."

Trevor (roc-LGn_fP0, 00:06:28.000, https://youtu.be/roc-LGn_fP0): "tells your pituitary gland to release more growth hormone and IGF-1, insulin growth factor 1" and "it's using your own system and it doesn't overdrive or overrev your system."

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.
