Blue Sky Peptide has a large COA library and clear shipping terms, but it names no lab, prices high and sells prescription drugs. On October 21, 2026, even with a 35%-off sitewide sale applied, 25 of the 31 listings we priced were above the median in our price index. Its 65 COA PDFs don't name the testing lab, and its 'research liquids' section lists drugs such as anastrozole, tamoxifen and tadalafil, plus SARMs.
Notice: Blue Sky Peptide's products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal use. This review covers supplier transparency and prices. We didn't buy or test any products. Some vendors pay us a commission when you buy through our links. That never changes a score or a price ranking.

Prices as listed on October 21, 2026, with the 35%-off sale already applied (the struck-through prices were higher). 25 of 31 listings were above the median per mg across the vendors in our price index. GLP-class listings were the furthest above: retatrutide 10mg 118% above, tirzepatide 10mg 112% above and semaglutide 5mg 141% above. The few below-median items were melanotan II (19% below), PT-141 (21% below), selank (22% below), semax (13% below) and DSIP (10% below). Even with the free vial, the TB-500 2mg deal works out to $5.84 per mg (17% below) and ipamorelin 2mg to $6.82 (8% above). See our BOGO deals page and the price index.
Shipping is US only, with no APO/FPO. USPS Priority is free over $75; otherwise Ground Advantage is $6.99 (3-5 days), Priority $12.99 and Express $34.99, with UPS Next Day available. Orders before 12pm ET ship the same day, and a signature is required over $500.
Testing and COAs
Blue Sky's COA library holds 65 PDFs, organized by product and labeled 'HPLC/MS ID + Purity'. That's more paperwork than many small vendors publish. The page says to contact support for previous batch COAs, which suggests each product shows its current batch.
What's missing: the library page doesn't name the testing lab, and the reports aren't presented by lot number, so you can't easily match a certificate to your vial. We saw no endotoxin or sterility testing, and Finnrick lists no independent tests for Blue Sky.
Red flags
Blue Sky's 'research liquids' section lists prescription drugs (anastrozole, letrozole, tamoxifen, clomiphene, finasteride, T3/T4, tadalafil), clenbuterol and SARMs (LGD-4033, RAD-140, MK-677, YK-11). Selling these alongside research peptides is a red flag under our scoring.
What we like
- A 65-PDF COA library organized by product.
- Detailed, published shipping options with a 12pm ET same-day cutoff and free Priority over $75.
- Claims a long history (since 2013).
- No-code promotions: 35% off sitewide plus BOGO and buy 2 get 1 offers.
What to watch
- 25 of 31 prices above our index median, even after 35% off.
- No testing lab named and no lot matching.
- Sells prescription drugs, clenbuterol and SARMs as 'research liquids'.
- No address or company name published.
- No Finnrick tests yet.
How it compares
Blue Sky's sale prices still trail cheaper vendors such as Maximum Peptides and Geo Peptides, and its COAs say less than those from Mile High Compounds, which names three labs and matches every lot. See all vendors we track and peptide deals this week.
Bottom line
Blue Sky Peptide is an established-looking store with a big COA library and clear shipping terms. Prices are high for most compounds even on sale, the library doesn't name a lab, and its catalog includes prescription drugs and SARMs. We'd compare per-mg prices and ask which lab ran the COA before ordering.
