Beyond the literature: here's what third-party Certificate-of-Analysis records (Janoshik, BCC, Auxlabs) say about real IGF-1 and Ipamorelin batches we've tested. Aggregate, public data — cross-reference against the studies below.
We tested 17 IGF-1 batches across 10 manufacturers, 99.17% avg purity.
We tested 1805 Ipamorelin batches across 638 manufacturers, 99.52% avg purity.
We hold deeper lab coverage on Ipamorelin (1805 batches tested). Ipamorelin edges ahead on average measured purity (99.17% vs 99.52%) — a narrow gap; weigh it against failed-batch and underdose counts above.
Studies in our corpus that mention both IGF-1 and Ipamorelin — the gold-standard direct comparison evidence.
These findings suggest that Ipamorelin could be a promising therapeutic agent for conditions characterized by growth hormone deficiency, sarcopenia, or osteoporosis. Its selective action as a growth hormone secretagogue receptor (GHSR) agonist, without sign…
This study highlights a critical paradox in diabetes: GH hypersecretion coexisting with peripheral GH receptor resistance. This finding suggests that the body attempts to compensate for impaired GH signaling by increasing GH production, but target tissues r…
This study unequivocally highlights the severe public health risks associated with the use of unregulated black market growth-promoting products. Consumers are frequently exposed to mislabeled, contaminated, or entirely fraudulent substances, leading to unp…
