To verify an IGF-1 LR3 listing, match the exact SKU to the stated per-vial size and vials-per-pack, then open the COA that names that same SKU and batch. A product name alone is not enough when more than one size exists, and a report for one variant is not evidence for another.
Listed SKUs, vial size, and pack quantity
The public record for IGF-1 LR3 lists two variants: IG01 at a nominal 100 mcg per vial with 10 vials per pack, and IG1 at a nominal 1 mg per vial with 10 vials per pack. It also lists CAS 143045-27-6, formula C400H619N111O115S9, and molecular weight 9111.5. Those are catalog fields, not batch measurements. The SKU table is public listed variants only and is not a claim that the list is exhaustive.
Reading per-vial size versus pack quantity treats per-vial size, vials per pack, and pack price as separate fields. A label such as 10 mg × 10 vials means ten vials of 10 mg each, not one 100 mg vial. For these listings, IG01 is ten 100 mcg vials and IG1 is ten 1 mg vials. A pack total from those fields is label arithmetic, not an analytical measurement. Actual fill and peptide content belong to the batch report.
| SKU | Nominal size per vial | Vials per pack |
|---|---|---|
| IG01 | 100 mcg | 10 |
| IG1 | 1 mg | 10 |
Check the exact product and SKU, the per-vial size and unit, the vial count, the number of packs, and matching batch records before ordering. If a quotation uses a different packaging description, ask support to reconcile it. Prices, stock, currency, and shipping are not in the product specification source used here.
Published batch COAs for IG1 and IG01
Finding a COA by SKU and batch treats a SKU as the listed variant and a batch number as the batch record. Compare product, SKU, batch, and certificate. Do not treat a report for one size as evidence for another. A published batch is not evidence of the batch that will ship next.
The LJ3PGSK1IE3F COA is SKU IG1, 1 mg, certificate QC-2026-2QJHEDNVRX, laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group), test date 2026-09-14. Scope: this batch only; provider verification links were not independently fetched; not evidence of clinical suitability or every batch.
Tests for analyte IGF-1 LR3 IG1:
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 9111.5 +/- 1.0 Da | 9111.7 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 99.5 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 91.4 % | Pass |
| Actual fill | Gravimetric | 1 mg | 1.06 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 4.4 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
The 86KHAJO2QOL5 COA is SKU IG01, 100 mcg, certificate QC-2026-ZG4R4HXBZ8, the same laboratory, and test date 2026-09-14, with the same scope limits.
Tests for analyte IGF-1 LR3 IG01:
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 9111.5 +/- 1.0 Da | 9112.3 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 99.2 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 92.2 % | Pass |
| Actual fill | Gravimetric | 0.1 mg | 0.109 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 3.5 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <1 EU/mg | Pass |
Purity and peptide content are separate HPLC results. Actual fill is gravimetric for that SKU: 1.06 mg versus 1 mg on IG1, and 0.109 mg versus 0.1 mg on IG01. Keep qualifiers such as <3 EU/mg and <1 EU/mg as written. Unknown tests are not zero, pass, or evidence of absence.
How to match and verify a COA
Verifying a CertiPeptide COA starts with product name, SKU, and batch number, then certificate number and test date versus the summary, then the report's verification link. Seeing a link alone does not prove the report is currently valid. A provider page may require an account.
- Read product and SKU from the product page or order documents.
- Find the batch; if it is not stated, ask support.
- Check certificate number, sample identity, test date, and laboratory on the batch page.
- Compare original-report values and units with the summary.
- Follow the report-specific verification link; if login is required or the record cannot be confirmed, resolve that with the provider or support before treating verification as complete.
This article does not independently confirm provider-hosted verification status. If details differ, send support the SKU, batch, and the difference rather than substituting another size. Confirm the allocated batch separately. A missing public result is neither a fail nor a pass. If a shared link is gone, ask for current documentation rather than swapping batches.
| Check | Match to |
|---|---|
| Product | IGF-1 LR3 |
| SKU and per-vial size | IG01 = 100 mcg; IG1 = 1 mg |
| Pack quantity | 10 vials of that size, not one combined vial |
| IG1 example identifiers | Batch LJ3PGSK1IE3F; certificate QC-2026-2QJHEDNVRX; analyte IGF-1 LR3 IG1 |
| IG01 example identifiers | Batch 86KHAJO2QOL5; certificate QC-2026-ZG4R4HXBZ8; analyte IGF-1 LR3 IG01 |
| Results | Same methods, units, and qualifiers as the named COA |
| Fill and peptide content | That batch only, not pack-sum arithmetic |
These sources do not specify vial materials, closures, storage temperature, sterility, or shipping. The COA records are not evidence of clinical suitability or of every batch. The site guides describe how to read product and batch records and do not establish suitability for human or animal use.
Frequently Asked Questions
Which IGF-1 LR3 SKUs are listed?
The public product record lists IG01 at 100 mcg per vial with 10 vials per pack, and IG1 at 1 mg per vial with 10 vials per pack. That table is public listed variants only and is not a claim that the list is exhaustive.
Does a published COA mean every IGF-1 LR3 order receives that batch?
No. Confirm the batch allocated to the order separately. A published batch is not evidence of the batch that will ship next.
Can the IG01 COA be used as evidence for SKU IG1?
No. Do not treat a report for one size as evidence for another merely because both are named IGF-1 LR3. The published IG01 example is batch 86KHAJO2QOL5; the published IG1 example is batch LJ3PGSK1IE3F.
What if a public COA is missing?
A missing public result is not automatically a failed test, and it is not a passed test either. Ask support for the exact SKU and batch. If a previously shared report link is no longer available, ask support for the current documentation rather than substituting a different batch.
