Hey Glenn! Glad to have you here! BPC/TB500 are really a great combo. It seems thats the gateway for most people. Whats funny is we know of more than a few clinics/spa's that give their clients "research grade".

There can be interactions between peptides that cause them to break down faster than normal when mixed, which is why you shouldn't let them sit together for too long. Also, some vendors sell things because people ask for them, not because they work better together. I would do four pins or boof it https://www.youtube.com/watch?v=XRzzwToLSiY
