- Real Peptides CJC-1295 no DAC consistently shows >98.5% purity and molecular weight within ±0.3 Da of target specification across production batches. Competitors offering similar claimed purity at 50% lower cost are almost universally using contract manufacturers in regions with minimal regulatory oversight—synthesis occurs in facilities we've never audited, and the peptides arrive pre-packaged with COAs we can't verify. The cost difference isn't markup; it's the expense of independent verification, small-batch precision, and accountability when a batch doesn't meet specification.
