Peptide Lab Guides
Method-first notes for handling research peptides at the bench and for reading the paperwork behind them. The handling guides cover mixing, diluents, arithmetic and storage. The documentation guides show how to read the Freedom Diagnostics Testing reports for LiliPeptide samples listed on our COAs page. The compound guides summarize what published studies examined, and each one ends by naming the listings and reports this store actually has for that compound. For research use only. Not for human or veterinary use.
Mixing Lyophilized Peptides
Plan the concentration, pick bacteriostatic or sterile water, mix without shaking, and record the batch code so a vial can be matched to a row on our COAs page.
BAC Water vs Sterile Water
What 0.9% benzyl alcohol does and doesn’t do, why multi-draw vials need it, the 28–30 day limit after first puncture, and which diluents this store lists.
Peptide Concentration Math
Four calculations for laboratory work: vial concentration, amount per draw, 1:10 serial dilutions and mass-to-molarity conversion, plus a lookup table for 5mg and 10mg vials.
Storing Peptide Vials
Storage by state, from sealed dry powder and freezer archiving to mixed solution, with what to check when a package arrives and how to spot a vial that has degraded.
Shelf Life After Reconstitution
Why dissolved peptides lose quality, planning windows at 2–8°C for each compound class, and the handling habits that keep a reconstituted vial usable for longer.
Reading Our Freedom Diagnostics COAs
A walk through the reports on our COAs page: matching sample, batch and report number, batch entries that aren’t lot codes, and the sections to read on the PDF itself.
HPLC and Mass Spec Basics
How reverse-phase HPLC turns peaks into a purity percentage, what the impurity fraction holds, why identity needs mass spec, and how to read a purity figure critically.
BPC-157 in the Literature
Gastrointestinal, tendon and blood-vessel studies of BPC-157, the limits of a mostly rodent evidence base, and the listings and single report this store has for it.
Thymosin Beta-4 (TB-500) Studies
Thymosin beta-4’s actin-sequestering mechanism, the skin, corneal and cardiac models, the eye-drop trials, and the point where the preclinical evidence ends.
BPC-157 and TB-500 Compared
Two repair peptides acting at different layers of tissue repair: assay choice, a feature-by-feature table, and the single-compound and blended listings in this store.
GHK-Cu Copper Peptide Research
The copper tripeptide since its isolation in 1973: collagen and wound studies, Connectivity Map gene-expression screens, topical cosmetic data, and bench notes on the blue complex.
Sermorelin, CJC-1295 and Ipamorelin
GHRH analogs against a ghrelin mimetic: receptors, half-lives, why pulsatility matters, the logic of pairing, and which related listings and reports this store has.
Semaglutide Research Notes
Semaglutide’s three structural modifications, GLP-1 receptor biology, the SUSTAIN, STEP and SELECT programs, and the directions laboratory work is taking now.
Dual vs Triple Incretin Agonists
Tirzepatide and retatrutide side by side: receptor balance, SURMOUNT-1 and phase 2 weight results, the glucagon question, and how to pick a compound for a study.
Retatrutide: The Evidence So Far
Engineered GIP, GLP-1 and glucagon activity, the 2023 phase 2 and liver-fat findings, the TRIUMPH phase 3 program, and the three retatrutide reports on our COAs page.
