Tiers name what a vendor publishes, not a verdict on any product's purity or quality. Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do). Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site. Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score. Affiliate relationships never affect tiers, selection or order. How the Vendor Score works
A truncated IGF-I analogue with reduced binding to IGF-binding proteins, studied mainly in preclinical models.
Evidence brief

Read original source: PMID 1710892 ↗Research use only — this reports what an FDA label, a peer-reviewed study or a clinical-trial registry entry published, tied to its species and study context. A trial-registry figure is what a sponsor registered, not a peer-reviewed result. It is not medical advice, not a recommendation to use, and no dose here is generated by pepmg.

Des(1-3)IGF-I, a truncated variant of human IGF-I with the tripeptide Gly-Pro-Glu absent from the N-terminus, has been isolated from bovine colostrum, human brain and porcine uterus. This protein probably results from post-translational…
The relative potencies of insulin-like growth factor (IGF-I) and the N-terminal truncated derivative, des(1-3)IGF-I, have been compared in lit/lit mice. Injection of 30 micrograms IGF-I, 30 micrograms des(1-3)IGF-I or 3 micrograms…
We have examined the effects of infusing recombinant human growth hormone (hGH), insulin-like growth factor-I (IGF-I), the truncated IGF-I analogue, des(1-3)IGF-I, and insulin over a 7-day period in streptozotocin-induced diabetic rats.…
