How to buy a research peptide with a per-batch COA in Mexico: what to ask for before paying, what to check on arrival, and what to archive. RUO guide.
How to verify a research-peptide vendor: what a real per-batch COA must contain, how to read an HPLC chromatogram, how to confirm identity, and the red flags. RUO guide.
Are peptides legal in Mexico? How Mexican regulation distinguishes a research reagent (RUO) from a medicine (COFEPRIS), how Égida operates within that framework, and what responsibility the buyer holds.
Tirzepatide vs semaglutide: which receptors each molecule activates (GIP and GLP-1 vs GLP-1 only), molecular weight and how each batch is verified by HPLC and COA. RUO guide.
What BPC-157 (pentadecapeptide, 15 aa, ~1,419 Da) and TB-500 (synthetic fraction of thymosin beta-4, ~4,921 Da) are: molecular identity, structural differences, and how to verify a batch by HPLC and COA. RUO guide.
What somatropin (recombinant HGH) is: 191 amino acids, ~22 kDa, how it is produced and how identity is verified by HPLC, tryptic mapping and MS against WHO standard 98/574. Technical RUO guide.

What research peptides are (RUO): what a peptide is, how it differs from a medicine, and how quality is verified with HPLC purity and a per-batch COA.
Yes, tirzepatide is a peptide: 39 synthetic amino acids, research use only (RUO). What it is and how a batch is verified by HPLC and COA.
How to reconstitute a lyophilized peptide vial with bacteriostatic water, calculate concentration and how many units to draw into the syringe. RUO guide.
RUO guide to reading a research-peptide COA: identity by mass (MS), HPLC purity, batch number and red flags. Step by step.
What HPLC purity measures in a research peptide, how it's calculated from the chromatogram, why the standard is ≥99% and what it doesn't reveal. RUO guide.
Differences between bacteriostatic and sterile water for reconstituting peptides: preservative, uses per vial and how it affects your calculation. RUO guide.
