Cell and tissue models examine IGF-1 receptor activation and downstream signalling.
Research investigates proliferation, differentiation and survival endpoints in controlled models.
Cellular activity does not establish a personal performance or body-composition outcome.
Studies examine myoblast, protein-synthesis and tissue-repair pathways.
Findings depend on species, tissue, exposure and experimental design.
IGF signalling is studied alongside insulin and metabolic-response pathways.
Growth-factor activity can have complex effects and requires qualified interpretation.

Weeks 1–2 · stronger muscle fullness may appear, while low-blood-sugar episodes are a key safety concern
Weeks 2–4 · recovery, strength and muscle fullness may increase; water retention can also occur
Weeks 4–6 · the source describes the strongest effects alongside possible receptor adaptation and joint stiffness
After observation · muscle fullness may fade over one to two weeks, while some training-related strength or size changes may persist
