Reset Biology Synthesis

Reset Biology suggests practitioners consider Hunter Williams's newer library framing (2026-03-30): "This is a peptide 200 or 300 level tool. Not for newbies." (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 22:16, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/). We'd ask the prescribing physician to weigh Hunter's "I prefer to do it post workout" (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 19:08, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/) against Taylor Williams's personal report: "my dosing with this peptide is um 50 micrograms and I take that um fasted in the morning" (nkOr0jCzn18, 00:13:20.399, https://youtu.be/nkOr0jCzn18).

Where they agree

Hunter Williams (2026-03-30): "it can be very helpful for putting on muscle for someone that is focused on just being healthy and focus on longevity and focusing on optimization." (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 1:44, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/). Taylor Williams (2024-08-16): "igf-1 lr3 is a great power peptide for the potential for building muscle." (nkOr0jCzn18, 00:05:42.080, https://youtu.be/nkOr0jCzn18). Dr Trevor Bachmeyer (2025-06-18): "It is IGF-13. Massive muscle recovery. So, I've heard hypothetically." (LCHv_rSnLlI, 00:36:13.359, https://youtu.be/LCHv_rSnLlI).

Where they differ

Hunter Williams's newer 2026-03-30 library source is the operative Hunter entry: "I prefer to do it post workout." (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 19:08, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/). His older 2026-03-29 use guide also records: "I like to take it before the workout." (igf-1-lr3-a-use-guide-for-practical-research-purposes--d337bad5, 14:15, https://library.hunterwilliamshealth.com/p/igf-1-lr3-a-use-guide-for-practical-research-purposes--d337bad5/). Taylor Williams (2024-08-16): "my dosing with this peptide is um 50 micrograms and I take that um fasted in the morning" (nkOr0jCzn18, 00:13:20.399, https://youtu.be/nkOr0jCzn18). Hunter Williams (2026-03-30): "Four to eight weeks on, equal or longer off. Maximum two or three cycles per year." (igf-1-lr3-for-body-recomposition-and-longevity--435267af, 19:40, https://library.hunterwilliamshealth.com/p/igf-1-lr3-for-body-recomposition-and-longevity--435267af/); Taylor Williams (2024-08-16): "I like taking it for 10 days on 4 weeks off." (nkOr0jCzn18, 00:15:01.919, https://youtu.be/nkOr0jCzn18).
