Royal Peptides is a newer vendor with a public per-batch COA library and community-independent testing by Janoshik Analytical. They offer a broad catalog of 64 peptide listings and accept credit card payments. However, their community presence is limited, with few Reddit and YouTube mentions. Shipping is reportedly efficient, but customer service feedback is sparse. They maintain a clean FDA record.

+Unusually deep 127-product catalog — one of the widest SKU counts we track, covering the mainstream injectables plus a long tail of less-common compounds (FOXO-4, Pinealon, Thymalin, ARA-290, SNAP-8, VIP, Oxytocin)
+Aggressive per-mg pricing on the GLP class — Retatrutide at $8/10mg single-vial ($8.00/mg) and Tirzepatide at $50/10mg ($5.00/mg) sit in the low tier of our tracked single-vial pricing
+Dose-scaling depth on core GLPs — Retatrutide in 5/10/15/20/30/50/60mg single vials, Tirzepatide in 10/15/20/30/40/60mg, Semaglutide in 5/10/20mg
+Bulk 10-vial kit pricing on most compounds — researchers running extended protocols can buy at roughly single-vial cost per kit-mg
+Strong coverage of hero blends alongside single vials (Wolverine, KLOW, GLOW, CJC+Ipa, BIMORELIN, Selank+Semax, Sermorelin+Ipa) — catalog breadth in the stack-blend category is above average
Cons
−Hyphenated domain (royal-peptides.com) is easy to typo — the non-hyphenated royalpeptides.com is a different site
−No third-party Janoshik / Finnrick COAs surfaced on the public product pages
−WooCommerce catalog structure overlaps single vials with 10-vial kits under the same variable product slug, which can confuse researchers looking only for a single vial
−Oral-capsule line (Dihexa, BPC-157 tabs, 5-Amino-1MQ caps, Tesofensine, MK-677, BAM15) — we don't track capsules for $/mg consistency, but buyers seeking injectables-only should filter carefully
−Customer-side coupon in the vendor dashboard is a personal name — we route discount through the affiliate link instead of publishing the code
Vendor states research-grade quality. No public third-party (Janoshik / Finnrick / Colossal) COA library on the site.
