The Helix Standard
Every product on this page, and every batch behind it, clears the same six checkpoints before it’s listed for sale.
99.9% verified purity, third-party HPLC tested, published as a certificate of analysis.
Every batch traceable from synthesis to dispatch, four checkpoints documented.
Each batch is lab-tested for purity, verified for identity, and screened for contaminants.
Manufactured in a cGMP facility in Texas with quality-verified standards for dependable research sourcing.
Labelling is excellent. Each vial is labelled with compound, mass, batch and a research-use-only notice. Makes our lab audit trail straightforward. Shipped in a foam insert with a cold pack.
Solid supplier for bench work. Reliable quality across three orders. Would like to see the 10mg size back in stock more often, it sold out twice when we tried to order.
Clean cake, clear reconstitution. The 5mg vial reconstituted fully in under a minute with gentle swirling. No cloudiness. Batch COA showed 99.1% purity and the mass spec trace was included, which we appreciate.
Peptides in lyophilized powder form (unreconstituted) should be stored at freezer temperatures of 17°F (-8°C) to -4°F (-20°C) for long term storage of 1-2+ years for minimal degradation. Reconstituted peptides should be refrigerated at 36°- 42°F.
Our peptides are in lyophilized (freeze-dried) vials. Lyophilization is a process that significantly increases the stability and shelf life of compounds. Short term temperature variations during transit times will not affect the integrity of the peptide and should still keep purity at 99%.
Orders ship the same day if placed before 1PM EST or the next day if placed after. Orders over $200 qualify for free Fedex 2-Day shipping. We also offer an insulated shipping option with a styrofoam lining and a large ice pack. Other couriers are available upon request (USPS or UPS).
