No medical, therapeutic or individual recommendation. Information is provided without warranty and used at your own risk. No liability for calculation errors, use, contamination, interactions or consequences.
Amounts, timing and cycles
Community/research information only
No generally accepted approved dose exists. Online amounts vary by material, purity, route and source and prove neither safety nor efficacy.
Amount status
Different amounts circulate online; no regulator-confirmed safe or effective dose exists.
Profile evidence level: preclinical.
Timing
Community claims about time of day, fasting windows or training intervals are not validated clinical standards.
No individual recommendation.
Cycle/duration
Cycles and breaks are community constructs and do not prevent adverse effects or unknown long-term consequences.
No individual recommendation.

复配与 U-100 换算
复配计算器
For clearly identified single lyophilised substances, the calculator only shows the arithmetic between vial amount, liquid volume and target amount. It does not check identity, purity, sterility, solubility, stability or solvent suitability. The entered target is not a recommendation.
复配计算器
Calculates concentration, volume and theoretical U-100 units. The preloaded 200 µg is only the reference page's arithmetic example.
Concentration

Calculation aid, not dosage or use advice. Incorrect inputs, a different syringe scale, measurement error, dead space or unknown vial content produce incorrect results.
Mechanism and research questions
PEGylated experimental MGF-related compound
PEG-MGF is classified as “PEGylated experimental MGF-related compound”. 旨在延长 MGF 相关分子的作用时间；缺乏可靠临床数据及批准。 This describes the investigated pathway but does not validate a community use, amount, route or combination.
聚乙二醇化IGF变体
这项研究考察附加在IGF-1片段上的化学修饰如何延长其在体内的活性时间,类似于让活性成分保持更久效力的保护涂层。在实验室模型中测量作用持续时间和组织标志物。
IGF-1剪接变体
这项研究考察生长因子IGF-1在组织中局部产生的变体如何参与肌肉细胞修复,类似于局部而非全身性的反应。在实验室模型中测量细胞生长和修复标志物。
生长轴放大
研究人员研究某物质如何放大从大脑到垂体再到生长激素的天然激素链,而不是直接补充生长激素。测量指标包括激素水平随时间的变化以及肌肉或脂肪量。
What communities discuss
These themes describe discussion and vendor claims. They do not prove benefit, safety, product identity or suitable use.
健身论坛
在这里,人们比较不同生长和修复肽之间的肌肉增长、力量提升和恢复时间,通常依据个人训练记录。商家和用户关于肌肉增长的说法属于个人经验之谈,而非对照研究结果。
恢复与损伤论坛
人们比较在使用不同修复肽时运动损伤后的个人恢复时间,通常基于主观疼痛量表。这类个体经历受许多其他因素影响,并不能证明疗效。
来源与纯度讨论
人们讨论哪些商家被认为更值得信赖,以及不同批次之间纯度检测结果的差异。这类社区评估基于有限的样本,无法替代对每一批次进行的独立实验室检测。
Adverse effects and risk boundaries
- 许多所谓修复肽缺乏对照人体研究。未知全身效应、免疫反应、出血或血管影响，以及注射相关感染和污染仍是核心风险。
- Local reaction, infection, abscess and contamination are possible with any injection that is not professionally manufactured and administered.
- A label or clear appearance does not exclude unknown purity, wrong identity, endotoxins or concentration errors.
Exclusion groups and professional assessment
- 妊娠、癌症、活动性感染、凝血障碍、计划手术及相关免疫疾病需要特别严格的专业评估或避免使用。
- Acute symptoms, allergic reaction, breathing difficulty, chest pain, neurological deficits or severe abdominal pain require immediate medical care.
- Children and adolescents, pregnancy/breastfeeding, and people with relevant disease should not be part of unsupervised experiments.
Monitoring and laboratory markers
- 未获批修复肽没有经过验证的监测方案。根据具体问题，临床表现、炎症征象、血常规、肝肾功能及凝血可能相关。
- Baseline, objective, measurement timing and stop criteria must be defined professionally in advance. Individual laboratory values cannot compensate for unknown product quality.
Evidence boundary
临床前
缺乏可靠的临床数据和批准。
Published evidence
现有数据主要来自动物或细胞模型;缺乏可靠的人体有效性和安全性数据。
PEG-MGF经过化学改造以在体内停留更长时间,不同于未经修饰的MGF。
Storage and stability
- The manufacturer label and prescribing information take priority. Storage instructions from a different product do not transfer.
- Unapproved vials often lack dependable stability data before and after mixing; ‘2–8 °C’ or ‘28 days’ is not a universal standard.
- Do not use after seal damage, particles, cloudiness, discoloration, unknown date or interrupted cold chain. Visual inspection does not prove sterility.
Troubleshooting and error sources
- U-100 units measure volume, not drug amount: 100 U equals 1 mL. A wrong concentration makes every unit figure wrong.
- Do not shake or dilute further to ‘fix’ cloudiness, particles or uncertain solubility; discard and obtain professional clarification.
- Do not calculate a double or extra amount to compensate for missed use or an uncertain injection.
- Without a COA, clear supplier, correct label and consistent vial information, identity is not confirmed.
Regulatory status and WADA
未获 FDA/EMA 批准
没有 FDA 或 EMA 批准的药品；有效性与安全性尚未确立。
WADA 2026
This profile is marked as WADA-relevant. Check the original 2026 Prohibited List and the specific sport/route; a prohibition may cover an entire class or related agents.

Combinations / stacks
- Combinations change effects, adverse effects and laboratory values; evidence for one substance does not establish the safety of a stack.
- Overlapping pathways may add up. Hormonal, glucose, blood-pressure, coagulation, immune and sedating effects are important potential interactions.
- Non-standardised blends prevent separate dosing, cause attribution and dependable reconstitution.
Frequently asked questions
Is an amount shown here a recommendation?
No. This page separates approved product information, study protocols and community information. No number or calculator is an individual dosing recommendation.
Does the U-100 calculator prove correct use?
No. It only converts mass, volume and syringe scale. It cannot check identity, purity, sterility, stability, solvent or medical suitability.
Can this profile be combined with other substances?
Safety of a combination cannot be inferred from a single-substance profile. Overlapping pathways, medicines and undefined blends can increase risk.
Which source controls when information conflicts?
For approved medicines, the current prescribing information and treating professional control. For research substances, conflict shows that no dependable self-use standard exists.
Are community claims clinical evidence?
No. Anecdotes can generate questions but do not replace controlled studies, regulatory review, or identity and quality testing.
