quick and tidy

MOTS-c shipped same day and arrived in four. Cold pack still cool, vial filled right, batch sheet tucked in. Would order again.

still waiting on a reply
Victor Z.

Placed an Epithalon order in early September and one of the two vials arrived with the cap loose and the stopper not seated right. I emailed support with photos the same day and a week later I still have not heard a word back. Really disappointing for a company that advertises US-based customer service. The other vial was fine, but the silence is what stings.

fine, nothing special
Felicia A.

NAD+ order came through okay. Vial was sealed and the fill looked normal, packaging was plain but did the job. Shipping took five days. It's a middle-of-the-road experience, neither bad nor memorable.

reordered three times now and still happy
Deborah Y.

I started with Pinnacle back in spring after a friend mentioned them, and I've since placed three separate orders across BPC-157, TB-500 and one of their pre-formulated stacks. Every single time the order has shipped the same day I placed it before the cutoff, and domestic delivery has run three to four days like clockwork. The vials are consistently filled to the same line, the lyo cakes look uniform, and the packing is genuinely careful with a proper outer box and a cold pack rather than the flimsy mailers some places use. My one previous source had gotten sloppy with fill levels and slow with replies, so the consistency here has been a real relief. The only thing I'd still like to see is batch-specific COAs posted publicly instead of the general compound sheets, but support did email me the lot documentation when I asked and answered within a day. Pricing is fair for a US-made product and the free shipping threshold is easy to hit. They've earned the repeat business.

took two weeks but the order was right
Tyler D.

I'm international so I knew it would be slow, and it landed almost exactly fourteen days out. Box arrived intact, GHK-Cu vial was sealed and filled properly, and the paperwork matched what I ordered. No drama, just a long wait.

good selection
Josephine V.

They had retatrutide in stock when half the vendors I checked were sold out. Vial fill looked right and it shipped the next morning.

ice pack was warm
Jasmine P.

Ordered semaglutide in late June and the cold pack was completely thawed by the time it reached me. Took six days in transit and the insulation was just a thin liner in the box. For summer shipping that is not enough, especially at these prices.

my new go-to
Noah T.

Third order with Pinnacle and they have not missed yet. Free shipping over $200 is a nice touch and everything arrives packed properly.

wish the COAs were on the product page
Damon V.

Product itself seems fine, no complaints on the CJC-1295 vial or the fill. But for a vendor that talks up third-party testing this much, I'd really expect batch-specific certificates posted on the site instead of having to ask. Shipping was quick at least.

solid US source
Dennis X.

Tirzepatide showed up double-boxed with a cold pack still firm. Lyo cake looked clean and the vial was filled to the line. Only knock is the COA in the box was a stock sheet, not my actual lot.

fast shipping
Austin E.

Ordered BPC-157 on a Monday and it was at my door Wednesday. Same-day processing is real with these guys.

fine but wish COAs were per batch
Richard R.

Decent prices and the order arrived in good shape. Just want batch-specific testing posted instead of a general purity claim.

okay overall
Justin Z.

Melanotan 2 starter kit came complete with diluent, everything sealed. Shipping dragged a bit at over a week. Fair value.

slow to respond
Christian Q.

Had a question about my order and it took nearly a week to hear back. Product was fine when it showed up but the support side needs work.

no complaints
Cynthia H.

Checkout was easy, order shipped quick, CJC-1295 with DAC vial arrived sealed. Solid mid-range vendor.

out of stock a lot
Sierra W.

Half the things I wanted were unavailable. What I did get (TB-500) came fine, but stock is hit or miss.

my go-to now
Marcus I.

Been ordering from them for a few months. Consistent shipping, vials always sealed and labeled right. Prices stay competitive.

fast domestic shipping

Three days to my door. Sermorelin and ipamorelin both well sealed. Pricing was reasonable.

Thymosin Alpha-1 quality exceeded expectations
Brooks Hamilton

Ordered Thymosin Alpha-1 after reading good reviews and wasn't disappointed. COA showed 98.9% purity with testing done by an accredited third-party lab. The vial was properly sealed and the powder reconstituted without any cloudiness or precipitation. Their packaging includes detailed handling instructions which is helpful. Shipping took 4 days with tracking updates at every stage. Customer support responded to my storage question within a couple hours. Price point is fair for the quality you're getting. Will definitely order from them again.

Monica O.

Order arrived intact and on time. Nothing wrong, nothing special. COA paperwork was thin though.
