Best research peptide company! My favorite company for research peptides. Their customer service is great, they are extremely responsive. On top of that they have the correct COA’s from top third parties as well as being tested with endotoxins which guarantees a good batch. Highly recommended and the price is hard to beat.

Hey guys I have ordered from core… Hey guys I have ordered from core peptide sports labs. Astro is legit. The owner has gone above and beyond for me. Whether with a new coupon. Or in his case actually dropping off my package for next day air for free. Actually took a picture and emailed me him at the ups. Or usps. If qr codes don't work. Just call or email the lab company for proof. Plus with a 30 fay money back guarantee how can u go wrong. I applaud the customer service. And people given bad reviews for doseage these companies legal can't give u recommendations. Just Google ex. Bpc 157 doseage and cycle and u will find great. But most take a couple mths to see results or u have to start out with a low dose build up tolerance. I highly recommend a journal and the dose adn how u feel and increase. Such has cjc too many people start put way to high and get Nasty side effects start out 100mcg a day x 5 days only th3n next week increase by 50. Plz people do research ask questions.
