The physical appearance of lyophilized powder (the “cake”) can vary based on the lyophilization process and the specific peptide’s concentration. It may appear as a solid cake or as broken fragments; this does not affect the purity, quality, or stability of the research compound.

Yes, we ship to most countries worldwide. We are experts in international logistics and use discreet packaging to ensure smooth clearance. peptidesonline.store provides a 100% Delivery Guarantee: if your order is seized by customs or lost in transit, we will provide a one-time free reshipment or a full refund.

For short-term storage, peptides can be kept at room temperature but should be shielded from direct light. For long-term stability, we recommend storing the lyophilized powder in a refrigerator (2-8°C) or a freezer (-20°C). Once reconstituted, peptides must be refrigerated and used within a short timeframe to maintain efficacy.

We take quality seriously. Every batch of our lyophilized peptides is synthesized to reach a purity level of 99% or higher. We utilize HPLC (High-Performance Liquid Chromatography) and MS (Mass Spectrometry) analysis to verify the identity and purity of our research compounds.
