重要安全与责任声明
本页记录并评估网络社区信息，不构成医疗或治疗建议、个体咨询，也不是使用邀请。
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.

Open community source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.

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
Synthetic ACTH-derived peptide
Semax is classified as “Synthetic ACTH-derived peptide”. 实验研究关注神经保护和可塑性信号；尚未获得 FDA/EMA 批准。 This describes the investigated pathway but does not validate a community use, amount, route or combination.
神经保护信号传导
这项研究考察某物质是否能保护神经细胞免受压力或损伤,例如在细胞模型中缺氧后的情况。在实验室条件下测量神经组织中的细胞存活率和信号标志物。
神经内分泌信号传导
这项研究考察神经系统与激素分泌腺体之间如何相互沟通,类似于连接大脑与远端器官的双向电话线路。研究人员通常同时测量血液中的激素水平和神经系统活动标志物。
抗焦虑信号传导
这项研究考察某肽如何影响动物模型中的应激和焦虑反应,类似于观察动物在陌生环境中是否保持更加平静。测量指标包括行为测试和应激激素水平。
What communities discuss
These themes describe discussion and vendor claims. They do not prove benefit, safety, product identity or suitable use.
益智药论坛
人们讨论服用实验性神经肽后对注意力、情绪或压力感受的主观影响,通常基于个人日记。这类自我报告的印象极易受期望影响,无法替代对照研究。
生物黑客与长寿论坛
用户比较自行组合的肽方案,以期影响衰老过程或能量水平,常常依据血液检测或主观幸福感量表。个人自我实验和营销承诺无法取代对照的长期人体研究。
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
- 中枢神经系统影响可能包括疲劳、躁动、头痛、眩晕、睡眠或情绪变化。未获批物质的相互作用及长期神经精神安全性不明确。
- 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、癫痫、严重精神或神经系统疾病，以及合并镇静或兴奋药物，均需医学评估。
- 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
- 研究可根据终点评估认知、睡眠、情绪、生命体征及不良事件；每日主观感受不能替代标准化测量。
- 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
尚未获得FDA/EMA批准;证据主要来自实验模型。
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。
Semax源自促肾上腺皮质激素,更多与神经可塑性相关;而Selank源自促吞噬肽,更多与焦虑和应激信号相关。
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
The atlas has no explicit WADA flag for this profile. That does not automatically mean every form, route or related class is permitted in sport.

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.
