What Is IGF-1LR31 Peptide?
Peptide as a Synthetic Variant of Human IGF-1
LeoLab RX describes synthetic peptide, also known as IGF-1 LR3, as a synthetic, bioengineered variant of human insulin-like growth factor 1, or IGF-1. This peptide is designed for laboratory research involving growth-factor signaling, cellular response, and receptor-related biological pathways.
Structural Modification of synthetic peptide
The structure of IGF-1LR31 includes an arginine substitution at position 3 along with an added 13-amino-acid N-terminal sequence. These modifications distinguish synthetic peptide from standard IGF-1 and are central to how the peptide is studied in research environments.
Reduced Binding and Increased Bioavailability in Research Models
These structural changes are reported to reduce the peptide’s binding affinity to IGF-binding proteins. In research models, lower binding to these proteins may help increase the peptide’s bioavailability and support more sustained activation of the IGF-1 receptor.
Research Areas for IGF-1LR31
According to the supplier, synthetic peptide is studied in research areas related to muscle growth, cell regeneration, metabolic activity, IGF-1 receptor activation, and PI3K/Akt signaling. These areas make the peptide relevant for laboratory studies focused on growth-factor pathways, cellular repair mechanisms, and metabolic signaling responses.
IGF-1LR31 Dosage Strength and Price at LeoLab RX
Synthetic peptide Dosage Strength, Not Human Dosage Protocol
When discussing IGF-1LR31 from LeoLab RX, it is important to refer to the product’s dosage strength rather than a human dosage protocol. LeoLab RX presents synthetic peptide as a research peptide intended for laboratory use, with the product strength clearly listed for research planning and product identification purposes.
1 mg Per Vial
LeoLab RX lists IGF-1LR31 as being supplied in a 1 mg per vial format. This gives researchers a clearly defined product strength when comparing peptide specifications, preparing study documentation, or evaluating the quantity needed for laboratory research applications.
Buy IGF-1LR31: Pick the Right Vial
Any peptide, including IGF-1LR31, should be used within 4 weeks (ideally) and no longer than 6 weeks, as its potency cannot be guaranteed beyond this period.
With this in mind, I’ve created a table to help you select the right peptide vial based on three key criteria:
- Your weekly dosage
- The strength of the vial
- The optimal cost per month
This way, you can make an informed decision that balances effectiveness, convenience, and value.
| Vial Strength | Price (USD) | Best For | Estimated Monthly Cost (USD) |
|---|---|---|---|
| 1mg | $105 | Suitable for researchers using lower weekly research quantities or starting-level laboratory study designs | Approximately $105 per month at lower weekly research-use quantities |
IGF-1LR31 Price at LeoLab RX
The current listed price for synthetic peptide on LeoLab RX is $105 per 1 mg vial. This USD pricing makes it straightforward for US-based buyers to compare the product with other research peptide options and estimate order costs before checkout.
Sterile, Sealed, Lyophilized Research-Grade Vial
According to the product details, IGF-1LR31 is supplied in a sterile, sealed research-grade vial as a white to off-white lyophilized powder. Lyophilized powder is commonly used for research peptides because it helps support stability during storage and handling before laboratory preparation.
Product Details: Form, Purity, Molecular Weight, and Storage
LeoLab RX lists synthetic peptide with a lyophilized powder form, ≥98% HPLC-verified purity, and an approximate molecular weight of 9,200 Da. The product page also states that the peptide should be stored at 35.6–46.4°F; after reconstitution, it should be aliquoted and frozen at −4°F, while avoiding repeated freeze–thaw cycles. These details help researchers assess product handling requirements, purity expectations, and suitability for controlled laboratory use.
How to Save When You Buy IGF-1LR31 Online in the US
Multi-Vial Discounts at Checkout
Researchers looking to buy synthetic peptide online in the US may be able to save by ordering multiple vials at once. Based on additional information from hcs-pharma.com, multi-vial discounts may be applied during checkout, allowing buyers to reduce the overall cost per vial when purchasing larger quantities for laboratory research needs.
Exclusive Promo Code: HCS-P1-10
Another way to save is by using the exclusive promo code HCS-P1-10, which provides 10% off. This discount can help lower the final order total when purchasing IGF-1LR31 or other eligible research peptide products.
Combine Quantity Discounts and Promo Savings
The best savings angle is to combine available quantity-based checkout discounts with the HCS-P1-10 promo code. This approach may offer better overall value for researchers planning to purchase multiple vials, especially when ordering in advance for scheduled laboratory studies.
Check Current Checkout Terms Before Ordering
Before completing a purchase, always confirm the final price, discount eligibility, and promo code application at checkout. Check current checkout terms before ordering, as discounts may change.
Independent Lab Testing for synthetic peptide
Third-Party Testing Claims from LeoLab RX
LeoLab RX states on its IGF-1LR31 product page that the peptide is subject to third-party testing for key quality markers, including purity, sequence, and biological activity. For researchers evaluating synthetic peptide, these testing claims can be an important part of assessing product consistency and suitability for laboratory use.
Independent Analytical Testing and Purity Verification
HCS Pharma notes that many peptide batches undergo independent third-party analytical testing, typically focused on verifying product identity and purity. According to HCS Pharma, tested batches may show claimed purity levels of 99% or higher, which can be relevant for researchers comparing suppliers and reviewing quality-control standards before purchase.
Look for a Batch-Specific COA Before Purchase
Before ordering IGF-1LR31, readers should look for a batch-specific Certificate of Analysis (COA) or an independent third-party lab report connected to the exact product batch being purchased. A current COA can help confirm identity, purity, and testing details, giving researchers stronger documentation than general product-page claims alone.
