Great peptides
Great peptides! I take a whole stack for workout and healing purposes. But, I’m currently healing from breast augmentation, and Doc mentioned how fast my scars are healing. Told her I was taking BPC-157 and TB-500. I usually take Glow, but I wanted individual vials for this surgery recovery. I’m 3 weeks post op, and she said my scars look like they’re 7 weeks post op.

Unmatched Quality and Support
Incredible selection and available inventory. High quality product with impressive COA’s. Customer support is unparalleled. This is my “go-to” company when I make a purchase.

Most important
Most importantly, the products Synthesis sells are exactly as advertised and highest quality.
I’ve gotten great results through customer service when I had a question about two different peptides.
