Research use only — what does that mean?
All Gentleman Peptides products are reference compounds intended exclusively for in-vitro research and laboratory use. They are not drugs, supplements, or for human/veterinary consumption. Lots are sold as analytical standards under research-use-only terms.
How are products tested and certified?
Every lot is independently re-tested at a separate accredited lab via HPLC-UV (purity), LC-MS (identity), and LAL endotoxin assay. The COA is generated from those results.
Why does product appearance vary between lots?
Lyophilization yields a white-to-off-white cake whose texture (fluffy, dense, or filmy) depends on excipient ratios and primary drying speed. Color and structure variation within spec is normal and does not affect purity or identity.
Lyophilized vs. solution form?
Most peptides ship lyophilized for stability. Some short-chain peptides ship pre-reconstituted in bacteriostatic solution where stability data supports it.
Powder color expectations
White, off-white, or pale-yellow are all within spec for most peptides. The COA records the exact appearance per lot.
Storage instructions
Store lyophilized vials at −20°C, desiccated, in the dark. Once reconstituted, keep at 4°C and use within 14–28 days depending on the compound.
