We offer peptides for sale as Peptides IGF1 DES 1 mg. IGF1 DES is a truncated insulin-like growth factor 1 variant, designated Des(1-3)IGF-1 because the first three amino acids at its N-terminus are absent. Peptide Sciences supplies it here as a 1 mg vial. The missing residues are small, but they change how the peptide interacts with binding proteins, which is the whole reason the variant is studied separately.
The chain runs to 67 amino acids and about 7.4 kDa as a single non-glycosylated polypeptide. With the first three N-terminal residues removed, the peptide binds IGF-binding proteins less readily, leaving more of it free to engage the IGF-1 receptor in experimental systems. Cultured-cell work has reported the truncated form as more potent than intact IGF-1 at equal doses, a laboratory observation rather than a clinical claim for a vial.
DES is not a spelling of LR3. LR3 carries a different N-terminal modification and a different binding-protein profile; DES is a cleaved form. IGF-1 DES is also not insulin, despite the family name, and it is not growth hormone or a GHRH peptide. Those distinctions matter more than the shared three-letter prefix.
Binding-protein behaviour is the practical reason this variant exists as a separate item. IGF-1 in circulation is largely carried by binding proteins, and the truncated sequence interacts with them differently, which is why results from intact IGF-1 cannot simply be read across. The 1 mg amount and the DES name together define what is in the vial.

Frequently Asked Questions
What is the active substance in IGF1 DES?
IGF1 DES is a truncated insulin-like growth factor 1 variant, designated Des(1-3)IGF-1 because the first three amino acids at its N-terminus are absent.
What mechanism should I understand before I buy IGF-1 DES?
With the first three N-terminal residues removed, the peptide binds IGF-binding proteins less readily, leaving more of it free to engage the IGF-1 receptor in experimental systems.
What structural or composition features are described for peptides for sale?
IGF-1 DES contains 67 amino acids: the first three N-terminal residues of IGF-1 are absent. The missing residues are small, but they change how the peptide interacts with binding proteins, which is the whole reason the variant is studied separately.
Which related-substance distinctions matter for peptides for sale here?
LR3 carries a different N-terminal modification and a different binding-protein profile; DES is a cleaved form.
Which names identify the IGF-1 DES for sale offered here?
The product is Peptides IGF1 DES 1 mg.
Which product form is offered within your range of IGF-1 DES for sale?
A vial presentation.
What amount is supplied with the IGF-1 DES for sale offered here?
1 mg, in the Peptide Sciences presentation. The DES variant name is part of the identity, not a quantity.
How can I check authenticity if I buy IGF-1 DES online?
Check the product's authenticity code on the manufacturer's official website after receipt. Keep the code with the batch and expiry details. Our peptides for sale range includes this product, supplied directly by its manufacturer.
