Il laboratorio di verifica è strutturalmente indipendente dall'impianto di sintesi, accreditato ai sensi della ISO/IEC 17025:2017.

FAQ

Domande frequenti degli acquirenti.

Which research peptide is most studied in 2026?

BPC-157 leads PubMed citations for tissue-repair research; Retatrutide leads clinical-trial enrolment in metabolic disease; IGF-1 LR3 leads anabolic-signalling research. All three are HPLC-verified at ≥99% purity in the IGF1 Shop catalog with per-lot Certificate of Analysis included.

What is the difference between IGF-1 and IGF-1 LR3?

IGF-1 LR3 has an Arginine substitution at position 3 of native IGF-1 plus a 13-residue N-terminal extension (Arg-residue-extension), reducing affinity for IGFBPs by ~5× and extending serum half-life from ~10 minutes (native) to ~20 hours (LR3). Both bind the same IGF-1 receptor.

Is Retatrutide better than Tirzepatide?

In the Phase 2 trial (Jastreboff et al., NEJM 2023) Retatrutide produced 24.2% mean weight loss at 48 weeks at the 12 mg dose, exceeding the 22.5% reported for Tirzepatide at 72 weeks (SURMOUNT-1, Jastreboff NEJM 2022). Retatrutide is a triple agonist (GLP-1/GIP/Glucagon) versus Tirzepatide's dual agonism (GLP-1/GIP).

How is purity verified on these peptides?

Every IGF1 Shop lot is analysed by reverse-phase HPLC at 220 nm against a reference standard (≥99% area-percent purity floor), confirmed by ESI mass spectrometry to within ±1 Da of theoretical molecular weight, and screened for endotoxin by the kinetic chromogenic LAL assay (<0.5 EU/mg). The chromatogram, MS trace, and LAL result ship with each order on the per-lot Certificate of Analysis.

What payment methods does IGF1 Shop accept?
