Every peptide protocol at Healthi Life is designed and prescribed by Dr. First. He reviews your goals, screens for contraindications, orders the baseline biomarker panel and chooses the protocol matched to your biology — never a template.

What are peptides?

Peptides are short chains of amino acids — typically two to fifty — that act as biological messengers inside the body. Unlike full proteins, they are small enough to reach specific receptors and trigger precise responses: tissue repair, hormone release, immune modulation, neural signaling. The body produces hundreds of them naturally. Production declines with age, illness, and chronic stress. Therapeutic peptides are lab-synthesized copies of these natural signals, administered at clinical doses to restore a pathway that has weakened. At Healthi Life, every peptide is USA-made, batch-verified with a Certificate of Analysis, and prescribed exclusively by Dr. First, a licensed Thai medical doctor. Each protocol is built around the guest's biomarkers, not a generic template.

"A peptide is a signal. The body still does the work."

Safety, sourcing and Thai regulatory context

Sourcing

Healthi Life sources peptides exclusively from USA-based lab partners that operate under documented compounding and quality-control standards. Every shipment is accompanied by a Certificate of Analysis (CoA) confirming peptide identity, purity and absence of contaminants. We do not stock peptides without a CoA on file.

Accreditations and certifications refer to lab partners and sourcing facilities only. Logos shown as brand-aligned wordmarks.

Prescribed by a licensed Thai MD

All peptides used at Healthi Life are prescribed exclusively by Dr. First, a licensed medical doctor in Thailand. Peptide therapy is not an over-the-counter product. It is not available without a physician consultation, a biomarker assessment, and a written prescription matched to the individual guest.

Thai regulatory context

In Thailand, therapeutic peptides may be prescribed by licensed physicians within the scope of clinical practice. Most peptides used internationally for longevity, recovery and metabolic indications are classified as investigational outside specific approved use cases. Healthi Life operates within this framework: physician-led, individualized, fully documented. We do not market peptides as cures. We do not prescribe peptides without consultation. We do not ship peptides outside the clinical relationship.

Frequently asked questions

What are peptides?

Peptides are short chains of amino acids — usually two to fifty — that act as biological messengers. They tell cells to repair, regulate hormones, modulate immunity or signal recovery. Therapeutic peptides are lab-synthesized copies of these natural signals, prescribed by a physician to restore a pathway that has weakened with age, illness or stress.

Are peptides legal in Thailand?

Yes, when prescribed by a licensed Thai medical doctor within the scope of clinical practice. Most peptides used for longevity, recovery and metabolic indications are investigational outside specific approved indications. At Healthi Life, every peptide is prescribed by Dr. First after consultation and biomarker assessment. We do not sell peptides without a physician relationship.

Do peptides have side effects?

Most peptides used at Healthi Life have a favorable safety profile when prescribed at clinical doses. Common short-term effects include injection-site redness, mild fatigue in the first week, and transient appetite or sleep shifts. Serious effects are rare but possible — this is why every protocol is MD-prescribed and monitored at week 4 and week 8.

How long until peptides work?

Most guests notice early signals within 2 to 4 weeks: better sleep, faster recovery, reduced inflammation, sharper focus. Full biomarker shifts — hormone axis, inflammatory markers, growth factor response — typically appear at the 8 to 12-week re-test. Tissue repair peptides like BPC-157 often show effects faster than longevity peptides like Epithalon.

Is peptide therapy covered by insurance?

In Thailand and in most international markets, peptide therapy is considered investigational or out-of-scope for standard insurance coverage. Healthi Life can issue itemized invoices and physician documentation that some private international insurance plans accept for partial reimbursement. We recommend checking with your provider before starting.

What is the difference between BPC-157 and GHK-Cu?

BPC-157 is a tissue repair peptide — best suited for tendons, ligaments, gut lining and post-injury healing. GHK-Cu is a copper-binding peptide — used for skin regeneration, hair follicle health and systemic anti-inflammatory signaling. They target different pathways and are sometimes combined in a single protocol when both objectives are present.

Who prescribes peptides at Healthi Life?

Every peptide protocol at Healthi Life is designed and prescribed by Dr. First, our Chief Medical Officer and a licensed Thai medical doctor. Dr. Petch, our Chief Medical Strategy Officer and International Board of Lifestyle Medicine certified physician, oversees integration with longevity programs. No peptide is dispensed without an MD prescription on file.

Can I combine peptides with NAD+ or stem cells?

Yes — many guests run combined protocols. NAD+ supports cellular energy and is often layered with longevity peptides like Epithalon or MOTS-c. Stem cell and exosome therapy is sometimes paired with BPC-157 or Thymosin Beta-4 to support post-procedure repair. Combinations are always physician-designed and biomarker-monitored.

How much does peptide therapy cost in Bangkok?

At Healthi Life, peptide protocols start from ฿50,000 for a full 8 to 12-week program. The fee includes a physician intake consultation with Dr. First, a targeted biomarker panel, InBody scan, USA-made peptides with Certificate of Analysis, two scheduled follow-ups and an end-of-protocol biomarker re-test. Total cost depends on peptide selection and protocol duration.

Which peptide is most studied for anti-aging?

There is no single answer. For cellular aging and sleep architecture, Epithalon is widely used. For growth hormone axis support, CJC-1295/Ipamorelin is common. For mitochondrial and metabolic aging, MOTS-c is used. The right peptide depends on individual biomarkers — telomere markers, growth factors, inflammation, mitochondrial function — assessed before prescription.

Is BPC-157 safe?

BPC-157 has a favorable safety profile in published research and clinical use, with most reported effects being mild and transient (injection-site irritation, short-term fatigue). It remains classified as investigational in most regulatory frameworks. At Healthi Life it is prescribed only after physician consultation and is monitored at week 4 and week 8.

How are peptides administered?

Most therapeutic peptides are administered as subcutaneous self-injection using a small insulin-style needle, typically once daily in the evening. Some are available as oral capsules (BPC-157), intranasal spray (Semax) or topical formulation (GHK-Cu). Dr. First selects the route based on the peptide, the indication, and the guest's preference and travel pattern.

Can peptides replace TRT or HRT?

No. Peptides like CJC-1295/Ipamorelin stimulate the body's own growth hormone release but do not replace testosterone or estrogen. Some peptides support the hormonal axis indirectly. If hormone replacement is clinically indicated, peptide therapy can complement but does not substitute for properly prescribed and monitored TRT or HRT.

How long can I stay on peptide therapy?

Most protocols run 8 to 12 weeks, followed by a break, biomarker re-test and reassessment. Some peptides (Epithalon) are run in short cycles twice a year. Others (BPC-157) are used as needed for repair windows. Chronic uninterrupted use is not recommended — Dr. First builds cycle-on / cycle-off schedules into every protocol.

Which longevity peptide is right for me?

It depends on the pathway you want to reach. Epithalon is widely cited for telomere and circadian effects. MOTS-c targets mitochondrial function and metabolic aging. CJC-1295/Ipamorelin supports the growth hormone axis. The right protocol is the one matched to your specific biology — never the one with the loudest marketing.
