Research Peptide Comparisons
Five groups of molecules that buyers and researchers most often confuse. Each page compares them on the parameters that actually differ — receptor pharmacology, half-life, mechanism class, documented identity data and list price — with the published source for every comparative claim.
GHRP-2 vs GHRP-6 vs Ipamorelin
Sequence length, published GH potency and efficacy, ACTH/cortisol effects and appetite endpoints across the GHRP family.
CJC-1295 with DAC vs without DAC
One linker, three orders of magnitude in half-life: albumin binding, GH stimulation pattern and analytical mass difference.
Selank vs Semax
Tuftsin-derived vs ACTH(4-7)-derived heptapeptides, the shared Pro-Gly-Pro stabilisation motif, and what human studies measured.
Argireline vs SNAP-8
The SNAP-25 N-terminal mimetic pair: six residues vs eight, terminal protection, and how chain length changes the assay.
BPC-157 vs TB-500
Two repair-research peptides with unrelated origins: gastric pentadecapeptide vs thymosin β4-derived fragment, plus the mass check that catches mislabelled material.
Why we publish comparisons instead of one catalogue page
Two molecules with different research profiles should not be described with the same paragraph. Each comparison states what is documented about each molecule, cites the published source, and names the parameters where the evidence is thin — including the points where a vendor's own catalogue data needs a second look.
Sourcing a whole cluster?
One quotation, one COA set, matched batch documentation across all molecules in the group.
