本网站使用 Sigma 名称自……
本网站使用 Sigma 名称，因为其他信誉良好的网站也有类似的名称，但产品是假冒的。 他们的瑞他鲁肽是假的，没有作用，最糟糕的是不知道你在体内放了什么。 他们来自哥伦比亚，他们有一个 Facebook 页面，上面有一些不错的评论，可能来自他们自己，但现在该页面已关闭。不要从他们那里购买任何东西。 而且他们不回复电子邮件。

Thank you for the review, but the claims here don't match any of our records and warrant a direct response. 1. We are a US-based company and ship exclusively from US fulfillment centers. Domestic delivery is 2-3 business days, which would be physically impossible from Colombia. Our shipping records, tracking numbers are all verifiable. 2. Every product we ship has a Certificate of Analysis (COA) displayed publicly on each product page. These are third-party HPLC test results, not internal claims. 3. We have a real, monitored support inbox at [email protected] that responds within 24 hours, often the same day. We are happy to look up any order under this name and address it directly. If you have a genuine order with us, please share your order number (privately or via support) and we will investigate immediately. If you don't have one, we'd ask you to consider that posting unverified claims about a business you have not transacted with is what Trustpilot's policy considers a violation. — Sigma Peptides Team
很可能不安全
结帐后，从我的卡上扣除的金额是双倍！ 多封电子邮件将“回复”链接到电子邮件，但随后会退回。 当交易仍悬而未决时，我能够向我的金融机构报告并取消交易，但花了更长的时间才尝试告诉公司终止交易。 每天还多次收到电子邮件轰炸——有英语和西班牙语版本。 谨慎对待这家公司。

Hi Jenn — thank you for taking the time to leave feedback. We take charge discrepancies seriously and want to look into this directly. A few clarifications that might help: 1. We do not double-charge customers. If you saw two pending charges on your card, this is most likely a temporary authorization hold (common with high-risk processors) that is automatically released within 3-5 business days. Only one charge is ever captured per order. 2. If your discount code didn't apply at checkout, the displayed total may have looked different from the final charge. We're happy to verify this against your order. 3. Our reply email address ([email protected]) is monitored daily and we respond within 24 hours. If your email bounced, please reach out again — something may have been flagged in transit. 4. Email frequency: we send one promotional email per campaign in both English and Spanish for our bilingual customer base. You can adjust your preferences or unsubscribe via the footer of any email at any time. Please share your order number (via [email protected]) and we will personally walk through the transaction with you and resolve any discrepancy. If there was an actual double charge, we will refund it immediately. — Sigma Peptides Team
