Saved me a ton of money vs compound pharmacy. Product is equivalent in effect. Thrilled.

DSIP is knocking me out within 20 min. Deep sleep numbers are solid.

Gotta say, domestic shipping was 8 days and every vial was intact. No complaints.

Nothing to reach out about. Everything went fine.

Great value. Quality is there and the prices arent gouging you.

FWIW, product did the job but communication was lacking. Hard to give more than 3 stars.

0 stars if I could. No tracking, took forever, and the peptides didnt do anything.

Reconstituted fine and seems to work ok. Just doesnt feel as strong as the same peptide from my previous vendor. Might try again

Well, worst shipping experience ive ever had. 17 days and they didnt seem to care at all.

Support was unhelpful. Generic reply that didnt actually address my question. Hard pass from me going forward.

Basically, highway robbery. These prices are a joke for the quality delivered.

Coming from someone whos ordered from like 6 different companies. this one is by far the best bang for your buck. Quality peptides at a reasonable price with fast shipping. Very happy customer.

BPC is the real deal from these guys. My shoulder tendon issue improved dramatically in about 2 weeks. Top marks from me.

Shipping was probably the best part. Got it in 4 days which is faster than most vendors.

Reached out with a question and got a thoughtful detailed reply within the hour. Impressed.

I mean, this was fine. Good product, reasonable price. Nothing to write home about on the shipping side but it got here.

FWIW, its ok. The powder looked a bit collapsed in one vial which wasnt inspiring but it reconstituted fine. Could go either way honestly.

took 6 days to arrive. About what I expected. Tracking was provided.
service

Honestly, didnt have any issues so never contacted them.

Ok so not worth the premium pricing. Product is fine but you can get the same for less. Learn from my mistake.
