Pros & Cons
Pros
- 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
