igf-1 lr3 vs hgh
igf-1 lr3 (F-tier) vs hgh (S-tier). mechanism, trials, evidence boundaries, dosing literature. side-by-side reference.
igf-1 lr3 — tier F
a free-circulating IGF-1 analog for muscle growth. sustained IGF-1 elevation carries one of the clearer cancer-risk signals in the literature.
a free-circulating IGF-1 analog. anabolic signal is real; sustained IGF-1 elevation carries one of the clearer cancer-risk signals in the literature.
WADA S2 banned in sport · half-life ~1-2 hours, estimated (no human PK); NOT long-acting, LR3 escapes the IGF-binding proteins that give complex-bound native IGF-1 its ~12-15h half-life · growth hormone
hgh — tier S
growth hormone. banned in sports, standard at every anti-aging clinic, expensive. works, with trade-offs.
growth hormone. eleven FDA-approved brand labels for endocrine indications. the off-label market is everything else.
FDA '85 Protropin · 11 labels · half-life ~2-4 hours (rapid-acting); ~1 week (long-acting variants) · growth hormone
