Excellent for research institutions
Product Quality: 5/5 Shipping Speed: 4/5 Customer Service: 4/5 Value for Money: 3/5
Ordered custom synthesized peptides for a research project. Biosynth delivered exactly what we specified with full analytical documentation. Their catalog of research reagents is massive — over 1 million compounds. Communication was professional but somewhat slow (2-3 days for quote responses). Premium pricing but you're getting pharma-grade quality.

Pharma-grade custom synthesis — not for casual buyers

Biosynth is in a different category from research peptide vendors. We use them for custom peptide synthesis at our pharma company. GMP-grade, full documentation, ISO certified. Quality is as good as it gets. But this is not a consumer vendor — minimum order quantities and pricing reflect institutional/pharma buyers. If you need pharmaceutical-grade custom peptides, Biosynth is excellent.
First order from Biosynth. SS-31 arrived in 5 days. Quality seems good — no issues with effectiveness. What stood out was their customer service. I had questions about reconstitution and they responded quickly with detailed instructions. Prices are fair. Will order again.
