Extended GH / IGF

Three separately labelled vials of lyophilized powder. The IGF-1 LR3 vial is 1 mg against 5 mg for the other two, and this is not a cost decision — IGF-1 LR3 is a folded protein above 9000 daltons whose activity depends on tertiary structure, so it is supplied at the quantity a signaling assay actually consumes rather than at a matched milligram figure that would sit in the freezer degrading.

Store the sealed tray at -20°C (-4°F). The two synthetic peptides remain within specification for up to 36 months; IGF-1 LR3 should be treated as the limiting component and held at -20°C or below with strictly no repeat freeze-thaw, since each cycle risks partial unfolding that purity assays will not detect. Reconstitute IGF-1 LR3 in weak acid rather than plain bacteriostatic water, and use reconstituted protein within a shorter window than the 14 days appropriate to the peptides.

This panel is arranged along a signaling axis rather than around a shared target. CJC-1295 with DAC engages the GHRH receptor and carries a maleimidoproprionic acid group that forms a covalent bond with circulating albumin — the drug affinity complex that gives it its name and separates it from the no-DAC version. Ipamorelin engages the ghrelin receptor. IGF-1 LR3 sits downstream of both at the IGF-1 receptor, a receptor tyrosine kinase, and its arginine-for-glutamate substitution at position three plus a 13-residue amino-terminal extension are what reduce its binding to IGF binding proteins.

Yes. Qualified procurement partners can request alternative vial strengths, additional replicates of a single component, unlabeled or private-label presentation, or an additional IGF-1 LR3 vial without the secretagogue pair. Contact our corporate sales desk with your target composition and kit count to scope the run.

Kits ship in light-blocking, vacuum-sealed secondary packaging with temperature-stability buffers holding the shipment in the frozen or refrigerated range through transit. Each vial retains its individual identity label inside the tray so component traceability survives handling. We ship nationwide across all 50 US states and internationally via express couriers with discrete, border-optimized clearance and full delivery assurance.
