- !Two Wyoming addresses appear: Cheyenne on the contact page and 30 N Gould St, Sheridan in the terms; both are common registered-agent addresses. GLP-class products are sold as PBL-SM1, PBL-TZ2 and PBL-RT3, and the ILS report we opened names the compound only as 'PBL-R3', so the lab does not confirm which GLP compound it is. Several 'regular' prices are more than 2.5 times the sale price (BPC-157 10mg $19 against $50.99), which reads as an anchor rather than a real former price. The site footer says it is powered by Sterling Path LLC. The domain was registered in September 2025, and Trustpilot notes the company has not replied to negative reviews.
