Commonly Asked Questions

Here are some of the most commonly asked questions by our customers.

What are Peptides
A peptide is a short chain of amino acids (typically 2–50) linked by peptide bonds, serving as smaller versions of proteins. These molecules act as key signaling molecules in the body, instructing cells on processes like hormone regulation, tissue repair, immune response, inflammation control, and growth. Many bioactive peptides help address deficiencies by providing or mimicking essential raw materials (amino acid building blocks) and elements needed for optimal health. When the body lacks sufficient precursors—due to aging, diet, stress, or other factors—supplemental peptides can support natural pathways, promoting renewal, vitality, and balance at the cellular level.
Is a Peptide a steroid or supplemnent

They are not steroids or supplements they are signals, a mini protien your body uses to send messages from cell to cell.

How does Tides For Life operate?
Tides For Life provides high-quality research peptides and bioregulators, prioritizing reliability, consistency, and thorough verification. Our products are produced through proven peptide synthesis techniques and backed by independent third-party lab testing.

How fast do you ship?

Most orders ship the next business day after processing. Typical delivery time is 2–4 business days once shipped (U.S. domestic), depending on carrier volume and destination. Tracking details are provided once your order leaves the facility.

Does My Body Already Make Peptides?

Yes, your body naturally produces many endogenous peptides. These are short chains of amino acids that act as signaling molecules, hormones, neurotransmitters, or regulators of various physiological processes like pain modulation, mood, growth, digestion, immune function, and more.Here are some key examples of naturally occurring peptides made by the human body: Some examples are Endorphins, Insulin, Dynorphins.
