Recovery. Optimized.

STLN Performance is available to adults 18 and older who are in generally good health. You'll complete a medical intake questionnaire and a licensed physician will determine whether peptide therapy is appropriate for you. Eligibility is based on your medical history, current medications, and individual health factors.

The online assessment takes about 10 minutes. Once submitted, a licensed clinician reviews your information — typically within a few hours during business hours. You'll receive notification when your case has been reviewed.

Most reviews are completed within a few business hours. If additional information is needed, the clinical team will reach out directly. You won't be left waiting without communication.

BPC-157 is a peptide fragment known for its targeted tissue repair properties — particularly effective for joint, tendon, ligament, and muscle recovery. TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide that promotes systemic muscle repair, improves flexibility and mobility, and accelerates wound healing throughout the body. The Combination Protocol stacks both for complete coverage — targeted and systemic healing in one protocol.

BPC-157 is used to support accelerated healing of soft tissue injuries including tendons, ligaments, and muscle tears. It is also known to reduce inflammation and support recovery from surgical procedures or acute trauma. Many athletes use it to address nagging injuries and recover faster between hard training cycles.

TB-500 is a synthetic peptide derived from Thymosin Beta-4, a protein involved in cell building and repair. Where BPC-157 works well for localized injury recovery — joints, tendons, and specific tissue damage — TB-500 operates more systemically. It promotes whole-body muscle repair, improves flexibility and range of motion, supports angiogenesis (new blood vessel formation), and accelerates healing across multiple tissue types simultaneously. The two peptides complement each other well, which is why many athletes use the Combination Protocol.

BPC-157 and TB-500 are compounded by FDA-registered 503A pharmacies and are prescribed by licensed physicians. Compounded medications have not been evaluated by the FDA for safety or efficacy as finished products. They are prepared based on a physician's prescription tailored to the individual patient. This is not the same as an over-the-counter supplement.

The intake questionnaire and clinician review process will help determine the most appropriate protocol based on your goals, medical history, and current health status. If you have a specific localized injury, BPC-157 is often the right starting point. If you're dealing with systemic recovery, mobility, or whole-body healing needs, TB-500 or the Combination Protocol may be more appropriate.

Both BPC-157 and TB-500 are typically administered via subcutaneous injection — a small needle just under the skin, similar to insulin administration. Detailed injection instructions and supplies are included with your shipment. Your clinical team is available to walk you through the process if needed.

Most patients with no prior injection experience pick it up quickly. Subcutaneous injections use very small needles and are minimally uncomfortable. Your shipment includes step-by-step instructions, and the STLN clinical team can provide guidance during your protocol.

Results vary based on the nature of the injury, your overall health, and the protocol selected. Many patients report noticeable improvement in recovery and reduced soreness within 2–4 weeks. For chronic injuries or significant tissue damage, a full protocol cycle is typically needed before peak results are observed.

Any adjustments to your dosing must go through your prescribing physician. Do not self-adjust doses outside of clinical guidance. The clinical support team is available to address dose-related concerns and will coordinate with your physician as needed.

BPC-157 and TB-500 are generally well tolerated. The most commonly reported side effects include mild injection site reactions (redness, swelling) and occasional fatigue or lightheadedness in the first few days. Serious adverse events are rare. Your clinical team will review your full health picture before prescribing and will monitor your progress throughout the protocol.

Yes. Both peptides are intended to support active individuals — they work alongside your training to accelerate recovery so you can maintain or increase your training volume. Always disclose your full supplement and medication stack to the clinical team to ensure there are no interactions.

Yes — injury recovery is one of the primary use cases for both BPC-157 and TB-500. BPC-157 is particularly effective for localized injuries (tendons, ligaments, joints), while TB-500 is well suited for systemic or widespread tissue repair. A licensed physician will evaluate whether peptide therapy is appropriate for your specific injury.

The STLN Performance clinical support team is available via your patient portal. For medical concerns during an active protocol, contact the team directly and your case will be escalated to your prescribing clinician as appropriate. You can also reach us at support@americanstln.com.

Peptides are shipped discreetly in unmarked packaging directly from the compounding pharmacy. Shipments are temperature-controlled where required. Most orders arrive within 3–5 business days of prescription approval.

Yes. You can cancel or pause your subscription at any time through your patient portal or by contacting the clinical team. There are no long-term contracts or cancellation fees.

Compounded peptide prescriptions are not typically covered by insurance. All pricing is straightforward and disclosed upfront. There are no hidden fees or surprise charges.
