What “tested” means here
- An outside lab. Every certificate on this site is issued by Freedom Diagnostics and carries the accession number it can be looked up by on their own portal.
- Per lot, not per brand. Where a lot has been assayed, the code printed on your vial matches a published certificate — purity, identity, net content, and endotoxin where the report ran one.
- Gaps are shown, not filled. Where a lot was not tested for something, its page says so instead of borrowing a sibling lot’s result.
The free handbook, still yours.
Seven chapters on handling, reconstitution math, storage and how to read a Certificate of Analysis. A copy by email, then a short series of follow-up notes and occasional updates — unsubscribe any time.
- 01What arrived in the vial
Why it ships dry, how to read the cake, and why vial weight is not peptide mass.
- 02Choosing your diluent
Bacteriostatic versus sterile water, what the preservative actually does, and solubility.
- 03The reconstitution math
mg/mL made simple — how solvent volume alone decides your concentration.
- 04Technique and sterility
Aseptic handling, why you swirl and never shake, and septum coring.
- 05Storage and degradation
Lyophilised versus reconstituted, freeze-thaw, and the signals material has gone off.
- 06What happens in transit
Why dry powder survives a hot mailbox, and what to check the moment it lands.
- 07Reading a Certificate of Analysis
HPLC versus mass spec, purity versus potency, and how to spot a decorative COA.
