What customers dislike about Singular Biotech

No Cold Pack Shipping Disclosed

The shipping policy makes no mention of temperature-controlled or cold pack options, which may be a concern for temperature-sensitive peptides shipped in warmer months.

Limited Transparency on Leadership

The company does not publicly disclose any leadership names, founders, or organizational structure on their website, reducing accountability transparency.

Membership-Gated Catalog

Full access to the product catalog requires member registration, which adds friction compared to vendors with fully open storefronts.

Low Community Confidence

Recent community feedback reflects declining trust, with limited Reddit endorsements and growing concerns about vendor transparency and consistency.

Below-Average Customer Ratings

Overall satisfaction ratings have dropped, with notable issues reported in customer service responsiveness and order reliability.

Went above and beyond

I made an order with singular and the experience was great. They are easy to communicate with and willing to work with you any way they can. These guys went above and beyond and went out of their way when I ordered a pack of 10 and didn't realize it needed two weeks before it shipped. They shipped it in a week for me and rushed it because I was leaving out of the country.
