EXCELLENT Based on 51 reviews Posted on L HannaTrustindex verifies that the original source of the review is Google. I’ve been impressed with them honestly for a local company here in Johnson City. From the first interaction, their team was knowledgeable, professional, and genuinely interested in helping me understand which products would be the best fit for my goals. They take the time to explain everything clearly—no pushy sales, just guidance with science to back. & The peptides are top-notch. Everything arrives well-packaged, properly labeled, with all ingredients and usage. I’ve noticed real results in both recovery and energy, and I feel more confident using a local company that stands behind their products. I don’t usually write reviews but figured why not.Posted on JeffreyTrustindex verifies that the original source of the review is Google. Been buying from this company for the last 4 years and never had any problems. 90% of the time you will receive your order within only 3 days from the time you purchase. All products are high quality and consistent with no variation. (Hard to find these days with sketchy companies) Another big reason for giving 5/5 stars is my experience speaking with their customer support. Super friendly, understanding, and I usually get a reply back the same day. (Depending if you actually send it while they are open). Also definitely sign up for their email for discounts that they send out every so often to save a few bucks.Posted on Yvette BryanTrustindex verifies that the original source of the review is Google.
