Key takeaways
- Two 1 mg recombinant protein vials are the smallest formats listed, both ≥95% by SDS-PAGE.
- CJC-1295 with DAC at 2 mg per vial is the smallest peptide format, ≥99% by HPLC.
- TZ-2 at 5 mg per vial is the lowest-priced option in the shortlist at $64.99 CAD.
- The 0.05 kg figure on each listing is packed courier weight, not net content.
- Log the lot number on receipt and match it to the downloadable certificate of analysis.
How the five vials were ranked
Laboratories running limited in-vitro work usually need the smallest net content that still covers the assay plan. The five vials below range from 1 mg to 5 mg per vial, each supplied lyophilized with a certificate of analysis per lot.
Three criteria decided the order. First, net content per vial: smaller formats rank higher for small-volume work. Second, the purity method stated on the certificate of analysis — HPLC for peptides, SDS-PAGE for recombinant proteins. Third, price per vial in CAD.
Every item ships from Vancouver with tracked shipping, in cold-chain packaging with desiccant. Ordering is limited to laboratories and qualified researchers. The wider Research Peptides catalogue lists 5 mg and 10 mg formats as well, and consumables such as bacteriostatic water and sterile 10 mL glass vials sit under Lab Supplies.
One note on shipping weight. Each listing shows 0.05 kg and 8×8×6 cm. That is the packed weight and carton size for the courier. The net content is the figure in the product name.
1. Recombinant IGF-1 LR3, 1 mg
Recombinant IGF-1 LR3, 1 mg Lyophilized Protein Vial holds the smallest net content in this shortlist at 1 mg per vial. Purity is stated as ≥95% by SDS-PAGE on the certificate of analysis for the lot.
This is the first pick for laboratories that want minimal material on hand and a single lot number against a short series of in-vitro plates. Recombinant proteins are supplied lyophilized and held cold.
Spec line: 1 mg per vial · lyophilized protein · ≥95% by SDS-PAGE · certificate of analysis per lot · $89.99 CAD.
2. Recombinant Follistatin Protein, 1 mg
Recombinant Follistatin Protein, 1 mg Lyophilized Vial is also a 1 mg format with ≥95% purity by SDS-PAGE. It ranks second on price rather than on format, at $149.99 CAD per vial.
Purchasing officers comparing the two 1 mg proteins should note that the documentation is identical in scope: identity, purity and test method, issued per lot and downloadable.
Spec line: 1 mg per vial · lyophilized protein · ≥95% by SDS-PAGE · certificate of analysis per lot · $149.99 CAD.
3. CJC-1295 with DAC, 2 mg
CJC-1295 with DAC, 2 mg Lyophilized Vial is the smallest peptide format listed here at 2 mg per vial. Purity is ≥99% by HPLC.
The 2 mg vial suits assay plans that sit between the 1 mg protein formats and a 5 mg peptide vial. Third-party HPLC and mass-spectrometry testing supports the certificate of analysis for the lot.
Spec line: 2 mg per vial · lyophilized powder · ≥99% by HPLC · certificate of analysis per lot · $79.99 CAD.
4. TZ-2 Acylated Peptide, 5 mg
TZ-2 Acylated Peptide, 5 mg Lyophilized Vial carries 5 mg per vial at ≥99% purity by HPLC. It is the lowest-priced vial in this shortlist at $64.99 CAD.
The 5 mg format is a single lot across a longer bench schedule. That keeps lot traceability simple when several plates are run over weeks.
Spec line: 5 mg per vial · lyophilized powder · ≥99% by HPLC · certificate of analysis per lot · $64.99 CAD.
5. Sermorelin, 5 mg
Sermorelin 5 mg Lyophilized Peptide Vial is supplied at 5 mg per vial with ≥99% purity by HPLC. Price is $74.99 CAD.
It ranks fifth on net content and price within this group. The documentation matches the rest of the shortlist: a downloadable certificate of analysis per lot stating identity, purity and test method.
Spec line: 5 mg per vial · lyophilized powder · ≥99% by HPLC · certificate of analysis per lot · $74.99 CAD.

Documentation, storage and ordering
Each lot ships with a downloadable certificate of analysis stating identity, purity and the test method used. Peptide purity is reported by HPLC. Recombinant protein purity is reported by SDS-PAGE. Third-party HPLC and mass-spectrometry testing supports the figures on file.
Vials travel in cold-chain packaging with desiccant, on tracked shipping from Vancouver. Lyophilized material should be held cold and dry, kept sealed, and logged against its lot number on receipt. Record the lot number in the assay notebook so the certificate can be matched to the data later.
Purchasing officers ordering for a Canadian university, contract research organization or private lab can quote the lot number on file when a repeat order is placed. Sales are to laboratories and qualified researchers only.
For laboratory research use only. Not for human or veterinary use.
