As growth hormone declines with age, building lean muscle becomes progressively harder. Compounds that restore natural GH signaling address the underlying driver rather than just working around it.
How growth hormone supports muscle
Growth hormone stimulates the liver to produce IGF-1 (insulin-like growth factor 1), which is the primary signal driving muscle protein synthesis. When GH levels are optimal, the body responds more efficiently to resistance training, builds muscle more effectively, and recovers faster between sessions. When GH is low, all of these processes slow down regardless of how hard you train or how well you eat.
Peptides like Sermorelin do not build muscle directly. They restore the hormonal conditions that make your training produce better results. The work still has to come from you.
Available through Tides
Sermorelin
Sermorelin is the primary compound Tides offers for muscle growth support. By stimulating natural GH production, it supports IGF-1 levels, which in turn supports muscle protein synthesis, fat metabolism, and recovery between training sessions. Most people using Sermorelin for body composition notice improved recovery within four to eight weeks and visible body composition changes after three to six months of consistent use combined with resistance training.
Lipo-C
Most people searching for muscle growth are really looking for body recomposition: more lean mass and less fat. Lipo-C supports the fat side of that equation by helping the liver metabolize and clear stored fat more efficiently. It is most effective when combined with consistent training and nutrition, and is commonly stacked with Sermorelin for a more complete body composition protocol.
NAD+
Training hard creates cellular stress and energy demand that NAD+ helps meet. NAD+ supports mitochondrial energy production and cellular repair, which translates to better recovery between sessions and more sustained energy during training. For people who train intensively, NAD+ is often a useful addition to a Sermorelin protocol.
Sermorelin vs. other approaches
| Approach | Mechanism | Safety profile | Timeline |
|---|---|---|---|
| Sermorelin (Tides) | Natural GH stimulation | Favorable, FDA-approved peptide | 3 to 6 months |
| Synthetic HGH | Direct GH replacement | Significant side effect profile | 2 to 4 months |
| Anabolic steroids | Testosterone and androgen mimicry | Significant risks | 1 to 3 months |
| Training and nutrition only | Caloric surplus and progressive overload | None | Ongoing |
How to get started through Tides
Start with a short online health assessment. It takes about five minutes and covers your health history, goals, and current medications. A licensed physician from the Tides network reviews your information the same day.
If a protocol is clinically appropriate, your physician writes a prescription. Your medication is filled at a licensed U.S. compounding pharmacy and shipped directly to your door. No clinic visit, no waiting room, no referral needed.
Your subscription continues monthly. Your physician is available for check-ins throughout your protocol. You can pause or cancel anytime before your next billing cycle.
Using Sermorelin alongside training
Sermorelin amplifies your response to resistance training, it does not replace it. The compound is most effective for people who are already training consistently and eating to support their goals. If you are new to training, establishing consistent habits first will give you the foundation needed to see meaningful results from a peptide protocol. Talk to your physician about when to start.
What to expect
Weeks four to eight: recovery between sessions improves noticeably. Sleep quality often improves in the same window, which compounds the recovery benefit. This is the window where most people notice they are less sore, sleeping deeper, and bouncing back faster.
Months two to three: training response improves and energy levels rise. People in this phase often describe feeling stronger in the gym and more motivated to train consistently.
Months three to six: visible body composition changes appear. Lean mass increases and fat decreases, particularly around the midsection. The combination of Sermorelin with Lipo-C tends to accelerate this phase.
Month six and beyond: full body recomposition results with consistent training and nutrition. Results vary between individuals. Your physician will help calibrate expectations based on your starting point and goals.
