We offer peptides for sale as Peptide IGF-1 LR3 ZPHC (Insulin-like Growth Factor growth IGF-1) 1 vial 0.2 mg. IGF-1 LR3 from ZPHC is a single vial containing 0.2 mg of lyophilized peptide, which is 200 micrograms. LR3 identifies a specific analogue rather than a brand variant: the Long Arg3 form of insulin-like growth factor 1. The pack is one vial and the 0.2 mg figure is its entire contents.
What LR3 changes
Native IGF-1 circulates largely bound to IGF-binding proteins, which slow its availability. The LR3 analogue carries an arginine substitution at the third position and a short N-terminal extension, modifications described as reducing binding-protein affinity without establishing that the peptide circulates for longer. Native IGF-1, by comparison, is cleared quickly once it leaves the binding proteins. That is a structural difference from plain IGF-1, and it is why the two are not interchangeable vial for vial.
IGF-1 in the growth hormone axis
Growth hormone released by the pituitary drives IGF-1 production in the liver, and IGF-1 mediates many of the growth and metabolic effects attributed to growth hormone, liver IGF-1 production being the link the endocrinology literature describes. IGF-1 acts at its own receptor, which is distinct from the growth hormone receptor. A 0.2 mg vial is therefore a small, concentrated unit that needs careful reconstitution arithmetic rather than bulk handling.
Choosing, then ordering
IGF-1 LR3 usually comes in vials measured in fractions of a milligram, so the 0.2 mg single is a small format that still demands precise measurement once reconstituted. A small vial is also easier to store and to finish than a bulk quantity, which is why the fraction-of-a-milligram format is the usual one.

Frequently Asked Questions
What is the active substance in IGF-1 LR3 ZPHC?
The active substance is IGF-1 LR3, the Long Arg3 analogue of insulin-like growth factor 1. IGF-1 LR3 usually comes in vials measured in fractions of a milligram, so the 0.2 mg single is a small format that still demands precise measurement once reconstituted.
What mechanism should I understand before I buy IGF-1 LR3?
IGF-1 LR3 is an analogue acting at the IGF-1 receptor, with sequence modifications that reduce its affinity for IGF-binding proteins. Native IGF-1 circulates largely bound to IGF-binding proteins, which slow its availability.
What structural or composition features are described for peptides for sale?
IGF-1 LR3 from ZPHC is a single vial containing 0.2 mg of lyophilized peptide, which is 200 micrograms. LR3 identifies a specific analogue rather than a brand variant: the Long Arg3 form of insulin-like growth factor 1.
